Just replaced a Concorde RG-35AXC after 6 years. It was maintained on a battery tender. Previously installed 3 Gill G35 batteries in 7 years,

My battery failed two days before a flight. I ordered on at 4pm and it was installed on my plane the next morning at 10am. A++ Thank you Aircraft Spruce!

Concorde Sealed Battery RG-35Axc
Good service
Concorde Sealed Battery RG-35Axc
Id like to suggest the Concorde applicability chart that Concorde is supplying to ASSCO and that ASSCO has posted is misleading. (Ordered wrong battery for customer.) I did a search on the pdf for T182T and the only hit showed this battery but it is not the right one. Owner confirmed it was right before ordering, but it was not right. The correct one is RG24-11M for this airplane but it does not show up next to the T182T. The airplane is factory, with no modifications. Use caution with the posted pdf.
Concorde Sealed Battery RG-35Axc
Excellent battery! Excellent service from Spruce. Just don’t leave your master on. Sometimes these batteries don’t recover if the voltage gets too low. My 4 year old battery would not come back to life from about 8 volts.
Concorde Sealed Battery RG-35Axc
Very good battery *****
Concorde Sealed Battery RG-35Axc
the battery was probably a good one , I was trying to upgrade from a gill battery but the top of the battery box would not fit over the concorde battery
Concorde Sealed Battery RG-35Axc
The battery was recommended by another aircraft owner on the field. Still waiting for it to be installed, but I know it will do better than the 6 year old battery I currently have in the plane.
Concorde Sealed Battery RG-35Axc
This one lasted 4.5 years with no battery minder/trickle charger. Previous one lasted 6+ years.
Concorde Sealed Battery RG-35Axc
Battery is specified for 1977Q Cessna Skylane. Will assess longevity with batteryminder

Decided to upgrade to a Concorde this time, since Gil equivalent wasnt available. Came well packaged and fully charged. Works great, but time will tell if its life significantly beats the lower priced alternatives.

Concorde builds the best aircraft battery,
Concorde Sealed Battery RG-35Axc
Works great… extra power for that hot start day!!
Concorde Sealed Battery RG-35Axc
One of the best batteries on the market. If you are a piper owner, please read the STC list carefully, older cherokees ned the RG-35, newer cherokees use the RG-25. Dont get this confused or you will make costly mistake that is not Aircraft Spruces fault.
Concorde Sealed Battery RG-35Axc
I ordered this battery because it was the only group 35 in stock. I paid more than the Gill but this really spins the prop on start. Installation in a Piper required the removal of the wood hold down in the original box but that wasnt a big deal. Hope it lasts a long time.
Concorde Sealed Battery RG-35Axc
arrived as scheduled in good condition.

These are fantastic batteries by a fantastic company with a excellent warranty program. My Archer IIs last RG-35AXC lasted over 15 years! I highly recommend these batteries. Aircraft Spruce also stands behind the products they carry. You can buy with confidence.
Concorde Sealed Battery RG-35Axc
Order was quick and correct
Concorde Sealed Battery RG-35Axc
Great overall experience. Delivery of the battery was very timely, condition upon delivery was excellent. Plus, that battery works well—have used it on two trips and it really turns the engine over!
Concorde Sealed Battery RG-35Axc
June 2018 to August 2018 with 620 flight hours and extremes of -40F in Wisconsin to 110F in Oklahoma, not bad for this battery

Perfect replacement, quick delivery, charged and ready to go.
Concorde Sealed Battery RG-35Axc
Replaced with exact battery. Starts O-360 effortlessly. What a difference.. our old one lasted 6 years and it was getting weak. New one is pricey but well worth it. Will buy again
This is the most expensive battery I ever bought! It turns the engine over with little to no effort. Quality costs! I will always use concorde batteries.
Concorde Sealed Battery RG-35Axc
This was placed into my Cessna 182k and it is a much better battery considering the upgraded avionics.
Concorde Sealed Battery RG-35Axc
Its a wonderful battery. But it cost tooo much and it doesnt last long enough!!!
Concorde Sealed Battery RG-35Axc
This is the only battery I will buy. Lots of power and a long life.

VERY STRONG BATTERY
Concorde Sealed Battery RG-35Axc
Great battery. Bought this one to replace the exact same one that lasted 12 years... yes 12. Fast shipping and a perfect fit!
Concorde Sealed Battery RG-35Axc
Not happy! Wrong voltage battery sent after ensuring that I needed 24 volt battery.
Concorde Sealed Battery RG-35Axc
I replaced an existing Concorde RG-35AXC which lasted about 4 years. In that time I havent been flying much, so the battery wasnt maintained as it should. It still lasted 4 years and Im very pleased.
Concorde Sealed Battery RG-35Axc
My RG-35AXC lasted 9 years. Gill flooded batteries were good for two years. Both solar charged in an aircraft that sits for long periods outside. The first cost of the Concorde AGM battery seems high. But it costs a lot less over time. Cheapest battery I ever bought : -)
Love this battery. The extra cracking amps made all the difference in my 210K. Before this battery, it struggled to turn over the engine and always required a couple bumps to get it past the first compression stroke. Now it just turns it no problem. Concorde supplied the STC and permission letter on request. Worth the money for sure.
Concorde Sealed Battery RG-35Axc
The battery is the best. The STC issue is pain. I tried to order from Wilco, but they did not have stock. So Spruce had the battery but no STC. Wilco has the STC but no battery.

Concorde Sealed Battery RG-35Axc
Gold standard battery if it fits your plane. Just replaced one that turned 6 years old on my I0-540 / Saratoga. It was still cranking just starting to show some signs of weakness. Only negative is that it’s gone up quite a bit in price over the last 6 years, but let’s face it, so has everything else.
Concorde Sealed Battery RG-35Axc
Best battery made!! My last one lasted 8 years!
Concorde Sealed Battery RG-35Axc

Great product. Great customer service!!!
Concorde Sealed Battery RG-35Axc
my last battery lasted 13 years. Well worth the extra money for the Platinum Series.
Concorde Sealed Battery RG-35Axc
Good battery! Have had several over the years, and its my favorite-never had a problem with it.
Concorde Sealed Battery RG-35Axc
Installed one of these about 3 years ago. Last week my charging system quit in flight in my Saratoga. With the concorde battery powering everything, I was able to run avionics for nearly 30 minutes until I got back to the airport, lower my landing gear and it was still at 12.3 volts. I mean it still had enough power to re-start the engine. I think it would have run the avionics and other equipment for a full hour or more if necessary. This experience made me feel like the extra money spent on the concorde battery was well worth it. I dont know that other batteries would have lasted until landing (and probably not had the power to get the gear down and light the critical 3 green lights). It turned what could have been a tense and challenging flight into a minor event.
Excellent battery. Last one lasted 7 years of being abused by the previous owner (not flying it or charging it and letting it freeze dead repeatedly). SInce the last owner didnt log the battery installation, Concorde helped me determine its age via the serial #. Quickly and happily. Price is ridiculous, but for ~$75/yr its not bad. Hopefully the next one will last longer with the BatteryMinder on it.
Concorde Sealed Battery RG-35Axc
Great battery, but very expensive. Last time I bought one the price was 60% of the current price. The good news is that it last 2X longer than the warranty.

I’m not a battery expert, but the previous Concorde RG-35 got 9 years of service before it started getting weak, so… another RG-35 it is. :-)

What a great battery. I replaced both the starter and the battery relays prior to buying the new battery thinking they were loosing power through them, with a slight improvement.

These Concord batteries are simply terrific. We began using both the 25s and 35’s , particularly the RG-35AXC in float planes and have found them to be reliable and trouble free. - even up to five years use. The most recent purchase replaced a five year old Concord but it had been left in the aircraft in an unheated hangar over winter with no trickle charger supporting it. Not the batteries fault it this case. While we don’t sell as many batteries as normal the customers are pleased. Mike

Concorde Sealed Battery RG-35Axc
Replaced my RG-35 with the RG-35AXC. First one lasted almost 10 years, never let me down once. The old one was finally getting weak so I was sold on buying another for my C182 and decided to get the extra cranking power of the AXC. Worked great right from the box.
Concorde Sealed Battery RG-35Axc
I like these batteries. The one being replaced work well for over 6 years. Others only lasted 2 or 3 years. It is worth the additional money.
Concorde Sealed Battery RG-35Axc
As advertised ... Great battery. Much quicker starts with the supercub now!

Was easy to install, about 5 minutes. Engine now cranks over completely when hot. Installed on 59 Comanche 250

Exactly as advertised. I checked the voltage upon arrival and it was 12.8 and the instructions said to just install it without charging. Plane fired right up. Installation was also very easy, fit right into my battery box. Very Happy!
Concorde Sealed Battery RG-35Axc
Good work correct product on time and shipped with enough packing for heavy battery
it will start the plane
Exactly what I ordered and delivered exactly when promised. Product (battery) performs great. Easy ordering process.
Like the power I have now, the engine starts better and the alternator doesn’t seem to need to put out as many amps while flying. The fit was perfect except for needing to adjust a spacer on the battery box lid.
Night and day difference over the Gill brand I had been using. Much more cranking power, spins the prop much faster. More expensive, but I am now sold on the Concorde brand!
The very best Battery fir my Bonanza.
I started with a Gill battery and got about 3 years service from it. I switched to the Concord RG-35axc and got 9 years of service and still working. I just replaced in the Cardinal 177B because I thought it was due. I also have always used the BatteryMINDer Model 12248-AA-S2 charger/ maintainer as recommended by Concord. I have used other BatteryMINDer charger/maintainers on other types of batteries with great results.
I am a tried and true Concorde fan, and polar opposite of Gill. I wouldnt pay good money for a Gill because of the terrible service they have.
This is the second time I’ve purchased this battery. The first one lasted about 15 years. It’s top of the line.
Great value.I love this battery. I got 5 yrs of service out of the previous two batteries of this type. The extra cranking power is handy sometimes during hot starts on my Bonanza.
Shipped very quickly from Aircraft Spruce. After installation, airplane started like never before in our experience ...very quickly.
Great battery.
Concorde RG-35AXC is a great battery. The last one we purchased was in installed in our Cherokee 180 that flies 500 - 700 hours a year in a flying club. We installed that battery in October of 2015 and replaced it in January of 2021, so we got more than 5 years of service out of it. We replaced the battery in the Cherokee not because it failed, but because it seemed to be getting weaker on cold mornings (at, or slightly above, freezing in Dallas), and we were tired of club members reporting that they werent able to start the cold-soaked engine. In the last 20 plus years, weve probably purchased 6 of these batteries for multiple aircraft and have never gotten less than 4 - 5 years of service out of one of these batteries.
The first start after install was almost instantaneous. The prop didnt make even make a full rotation before it started. I highly recommend.
Excellent product and exceptional customer service.
Love these batteries! They are by far the longest lasting and most powerful of the various batteries I have tried in my Lycoming O-540 powered Cherokee!
Last one lasted 7 years.
As expected, same one I used last time
Good start. Maintenance free
Replaced a Gill that only lasted just under 3 years in my M20J and am very happy. With the first start attempt on the Gill, the prop would only turn about 1 revolution and stop, then had to try a second start that would turn more revolutions. The Concorde spun the prop normally on the first start attempt - couldnt be happier.
all good!
Thanks, you are certainly my go to source for airplane parts.
Our last one lasted over 5 years with regular use. Hard to beat that from a battery.
Fair price. Quick delivery. Well packaged.
Arrived very quickly. Thank you!
The RG 35xc currently installed in 2 airplanes are on their 7th year...but it is time to replace, hence this order
This is a great battery. However, I had to reorder the battery as the first one was received damaged in shipment. I have made the mistake of not checking the damage immediately after opening the box and started cutting away some of the plastic material to make wires fit perfectly within my Cherokee battery box. Aircraft Spruce was understanding of my dilemma and sent a new battery. Great service. Thank you!! The replacement battery arrived in perfect condition.
They can last 5 plus years if plane parked inside.
Battery arrived when promised and, since it replaced a previously installed Concorde, it fit like a glove and worked like a charm. I looked up the installation date of the old Concorde and was shocked to find that it had lasted me 13 years - despite the fact that I never treated it particularly well. I hope this one lasts as long.
Excellent service / excellent product.
First battery came in damaged. You immediately sent a replacement and picked up the damaged one.
Work well
Great service.
Concord batteries are top quality, long life and great performance. Wouldnt trust any other brand in my aircraft.
Easier starts with extra cranking power. Dropped right into my Debonair with no troubles.
It appears to have done the trick. It fits in the plane as expected and appears to have good cranking power, time will tell.
Ordering was easy, it arrived in perfect condition within a couple of days and replaced the same battery, which showed no sign of any corrosion after 3.5 years. Replacing the battery was proactive maintenance, not a requirement.
Aircraft Spruce delivered the battery on time as promised and it was exactly as i ordfered ande per4formed perfectly.
Best investment / addition Ive purchased for the plane. After 3 of the other Batterys in 3 years the swap to the Concorde was a very pleasant experience. HIGHLY recommend!!
This is the third Concorde RG-35AXC in 13 years of ownership. :: the first was in the airplane when I bought it. :: The second I installed in September, 2011, and consistently used the bespoke desulfating BatteryMinder by VDC Electronics -- except that sometimes when in for maintenance my request to keep the charger hooked up was forgotten. Maintence is *hard* on batteries because the master switch goes on and off many times through the days or weeks, and this, without recharging, causes loss of capacity and sulfation. Finally, in August, a mechanic failed to start the engine properly after maintenance and ran the starter until the battery was flat. Despite the BatteryMinder, the battery had lost so much capacity that the starter labored to turn the engine. So... 2 after 2 weeks short of 9 years of service, I replaced the battery. It was 5 weeks past manufacture, so I put it on the BatteryMinder before I put a load on it. The engine turns over just fine... I expect good service from this one as well.
Great
I have been using Concord batteries since 2001 when I bought my first airplane I believe they are better than the other major brand and I get at least 6 years service from them. Aircraft Spruce delivered the battery quickly after my order and shipping was included in the price which was very reasonable.
Excellent product delivered in a timely manner with no errors made by Aircraft Spruce. Met my expectations and the battery is fully operational. Good Job!
Replaced identical model installed in 2011. Almost 10 years of service. What more can you ask for?
Super fast shipping!
Everything went as planned. Battery arrived safe and secure in a few days.
It starts my O-540 engine and takes a charge from my alternator. What more could you want?
Price was less than Amazon, delivery was quick and on time. Plane was back up in short order. Very happy
Battery came almost immediately (2 days) and was in perfect condition. Great company!
good product
Working well so far.
All excellent
Works well
Quality product that has been my most reliable aircraft battery.
Two day shipping, came sufficiently charged to install right away.
The item was what was ordered, it arrived undamaged.as scheduled.
Heavy duty. Does the job. Last one lasted four years.
Thanks
Alls well, item arrived in a timely manner as promised, arrived in good condition, I am Happy!
This battery ordered to replace same. Last one lasted 5 years. Rapid delivery from Aircraft Spruce.
Awesome battery. This is the second I have purchased. Long life, No maintenance. Definitely worth the little bit extra for the AXC.
Ordered battery. Received battery quickly. Installed in plane next day. Started just like it should. Had a great local flight, just drilling holes in the sky. 5 of 5
Great battery! Amazing fast delivery. Thanks Aircraftspruce.
Got tired of jumping my Cherokee due to low battery so bought this new Concorde. Dropped her in, hooked her up and Cherokee fired up like a champ. So far, so good. Time will tell.
I live at south western Arizona and get 6 years of service out of these Concord’s. The cheaper brands last 3 at most. They are expensive but won’t leave you stranded at a strange airport without warning!
Excellent service, as always. The product arrived promptly and was installed on my aircraft that day.
Just got it. Easy install, works fine, hope it will last a long time.
Best battery on the market. I requested the STC application from Concorde, sent it back and within 15 minutes it was in my inbox.
Best battery for my Bonanza
I have had airplanes since 1999. My previous batteries never lasted more than four years. My current airplane has had a Concorde battery installed since 2012 and its now just starting to fail. I am happily ready to purchase a Concorde replacement.
The battery, of course, was perfect. The delivery was exceptional. I had the battery in my hands in 2 days. Could not have been better.
highly competitive price, free delivery, tracked delivery that was on time. Awesome
Battery came on time and is working as advertised. Concorde makes a good battery
15 years ago I was paying $100 for a Gill in my 182. 10 years ago I opted for this Concorde RG-35axc. I will repeat that purchase next time I need to replace the battery. More starting power than the old wet cell. I have had the plane sit in the hangar for 3 months in Idahos cold winter, started right up after sitting that long. Also after ten years it performs at least 90% of new, not ready to swap it out yet, very long lasting. Expensive? Sure is. Worth it? damn right.
My plane starts sooo nice and fast Thank you very much
I recently just replaced my previous RG35 sealed battery with another one and I am very satisfied with my choice. The old battery was showing signs of age and it is definitely noticeable with the new battery and how rapidly it spins the prop and maintains a proper charge. As long as I own an airplane Ill always use Concorde Platinum Series sealed batteries.
I just replaced my first RG-35AXC with a second one after 10 years of use. It was still cranking the engines on my Seneca II albeit a little more slowly than when new. But after 10 years, I think I got my moneys worth. It never let me down once in 10 years. Hope to get 10 years from this one. Didnt hurt that I always kept a battery minder on it in the hangar.
Nice form/fit function for Gill. Shipping was perfect. Thanks, Bruce
Thanks
Have had very good luck with these batteries. No battery fluid spillage or evaporation. Cranking power is always there. I strongly recommend it!
My last Concorde RG-35AXC battery lasted 6 years. They are good batteries with no service required and no leaks. Aircraft Spruce shipping speed was excellent. Thanks
Batteries received on time, in a serviceable condition without any defect.
Ive replaced a 7 year old Concorde RG-35AXE with this new battery. The old battery works fine but I cant trust it at seven years old. I got this new one and I have the old battery at home for backup in my home solar charger. Excellent product.
Excellent service
The previous one of these lasted 5 years in a Cessna 180. Best battery performance ever. One day delivery was great.
Replaced the previous RG-35AXC which was still turning over an O-540 after almost 8 years although getting weaker in cold temps. Fresh battery delivered with a good charge. Spins the prop much faster now. Hope to get another 8 years out of this one. Excellent service with free shipping included.
Expensive but powerful battery.
On time delivery, packaged well, easy to install. Hope it performs better than replaced battery
Arrived quickly (2 days), worked as-expected.
Good staff
You always deliver fast. Some how I got the wrong battery and you immediately corrected it and sent me the right one with a label to send back the exchange. Thanks for your fine service.
Arrived on time, properly wrapped, no damage. The cost was similar to that of a Harley Davidson (HIGH).
Excellent
Delivered quick and got me back in service!
Just purchased the RG-35AXC to replace my last one, which lasted 7 years. Very reliable, powerful battery.
Just replaced the one in the plane after 5.5 years, so not too bad. I hope this one lasts just as long!
Just received my latest RG35AXC. The first one lasted 8.5 years!!! It will still start the plane, but is getting a little weak even after charging with the battery minder. Concorde is the only battery Ill use.
Concorde has become the battery we suggest to our customers. They do a great job and priced well.
Came on time, undamaged and as advertised. Premium product.
Bought one in 3/2012 and it is beginning to crank a little slow. Looks like almost 8 years out of the battery so I will be buying another in the next year.
Good battery and will last
No surprises
Good value for a great battery
Excellent drop in replacement. I had the RG35a and it was in for 10 years before the cranking power started to drop hope this one lasts as long.
The battery came to me fully charged. I installed it into my plane, checked the electrical system and then took off for a few times around the pattern. So far, Im very pleased with the new battery.
Great item - bought to replace the exact same battery because the original one was so good!!!
Shipping was fast and the ordering process was quick and accurate. Thank you.
Strong battery! Easy to handle installation.
Easy Website Navigation, Easy Payment Options, Excellent Product & Super fast shipment- thanks!!
Great battery. Can’t go wrong- my last one lasted 5 years
Great battery with plenty of power.
Great product. Fast delivery
Concord is an excellent battery !! I changed mine out with 5 years in service and still starting my twin good. I have heard of Concord batteries going but for the price and dependability you can’t go wrong.
An exact replacement for a 5 year old concorde Rg-axc which was getting sluggish but still firing up my Beechcraft Sundowner. Arrived from ACP East to Tallahassee, Fl., in about 3days, faster than a letter! I left a note to leave on the step so I would not have to carry downstairs. Concorde provides good long service and is about good as they get. Have been buying from AirCraft Spruce when they started out mostly selling spruce, dope and covering supplies near the Griffen airport. Great Company!
Timely and accurate.
Arrival in 2 days with free shipping in good condition and has great cranking power.
Cant say enough about the Quality & Fit.
The battery is my standard but getting it from Aircraft Spruce makes it a no-brainer. Fast, cheap, and easy.
Needed a new battery to give the freshly overhauled io520 in my C185 floatplane some cranking juice. No worries of hung starts now! Have to wait till winter to see how good it cranks when below freezing. No hazmat shipping is a big plus here in rural Alaska too.
Purchased in 2008 and still going strong 11 years later. Starting a 200 hp IO-360 with 640 hrs of operation in an AcroSport 2 . Best battery going.
Extremely fast shipping. Had it in two days. Shipping was free too! Battery arrived ready to install and in perfect condition.
This is the second Concorde sealed battery I have used. The first lasted well over four years, and is still showing good voltage. However, the capacity seems to be somewhat diminished, and I don’t want to stress the charging system. I do recommend using a Battery Minder with this type of battery.
The battery arrived earlier than expected, packaged well, and with complete documentation. It was the correct model, as ordered, and it fit and performed as expected.
Shipped in good condition, charged from the factory, installed in place of the g35 Gil I had, fit perfectly in the Hammock aviation stainless steel battery box and spun up the io520 like it had the plugs out. My first Concord. It defiantly will not be my last.
Good Experience
This battery has significantly more cranking amps and less maintenance due to being sealed. Important to do new weight and balance as it weighs 5 lbs more in order to get extra amps. I keep this on manufacturers recommended “ battery minder” charger in the hanger to extend life and health of the battery
Pricey, but a direct drop in for my 1958 Piper Tri-Pacer PA22-150/160.
Always a good choice...last one was in service for 4.5 years...Speedy 3 day delivery from Spruce...
I just bought a new one of these (RG-35AXC) to replace the one I bought 6 years ago.
I just took one of these out of service that had been in service in the aircraft for 9 years! I installed one in my own Piper PA-12 3 years ago. Still going strong. With 48 years in the aircraft maintenance business and after servicing hundreds of batteries, this is the best battery for airplanes I have ever been around. And no boil over mess.
Arrived quickly and shipped easily since it’s sealed.
fast shipment and just what I wanted
Last one only lasted nine months. I noticed something different about it when I installed it. I have one that lasted six years. I hope this one lasts that long or longer.
American made in the tradition everything used to be. Got 8 years out of my last wet one in my Trubo Arrow IV, delighted to trade up to maintenance free. Bought brand new Batteryminder to go with it as my previous was too old to upgrade to sealed battery specs, and had them send me a remote temp sensor to go with it as in the winter I heat the interior of the Arrow while the charger is external in a very cold hangar, so the attached sensor is innacurate. Expect to get many years of reliable use, it’s an excellent product. Found out recently Concorde makes milspec deep cycle batteries for marine and RV use, ordering some as well.
Great battery. Will last 5 years (capacity at or above 80%) with proper maintenance. Use the Concorde recommended Battery Minder.
Arrived well packaged and ready to install. This battery along with the Batteryminder has kept my 1967 B33 starting like a champ. Even in the hot 100 plus degree days in hangar storage in Texas.
I have had long service from regular RG-35A batteries since 1990 but was never able to crank the IO-550 in my C-182 thru on the first try. Recently tried a RG-35AXC and for the first time since the IO-550 install in 1996 it cranks thru compression on the first try , every try , even in below freezing weather. Wish I had known the AXC version was so much more powerful a long time ago. Im sold.
Best battery I have seen in my 46 years as an active A&P, and an IA. lasts way longer than your typical aircraft battery, with no boil over damage to battery boxes.
Best battery made
This is the third time I have purchased this battery for my Turbo Lance. The first battery I got 3 1/2 years and the last one got just over two years. This battery is worth the extra $$$ over the red one. No spills and plenty of juice to turn over the big Lycoming.
Best battery available, but not cheap. Last one, I changed out after seven years.
Great battery arrived in less than 2 day.
The first Concorde RG-35AXC I purchased lasted 10 years on my Cherokee 140. I kept it maintained with a Battery Minder with a desulferizing function. This new one came promptly and in good shape. Voltage measured 12.65 volts so I put it on a trickle charger overnight before installing to bring it up over the recommended minimal voltage. It works great and really spins my 0320 Lycoming. Would highly recommend this battery and Aircraft Spruce. Great product- no leakage or battery box corrosion or terminal corrosion for the life of the previous battery.
Best battery in the business. This is my second one in 5 years.
Good battery. For Cessna 182P was disappointed in having to modify battery cover to make battery fit. Got mod drawing from Concorde as they know the battery doesn’t fit these airplanes. Mod was easy but would have like to have known before I purchased.
This is my second Concorde battery. The first one went to seven years. The three gill batteries before that went an average of two years each and they spewed acid on the inside of my battery box. This one will not do that. Just be very careful with tightening torquw on the terminals because it can strip easily and other than that it’s the best thing going
Installed 9/2011, maintained with BatteryMINDer Concorde-bespoke charger, aircraft voltage regulator set at 14.2v. Lost the alternator in IMC last month, drew the battery down to 11.8v. Now does not take a full charge. Excellent longevity given this stress.
The five star rating is solely on expectations based on the last Concorde RG-35 battery I had. It lasted 8.5 yrs, and I used a generic battery minder when parked. The battery had always performed well and there was no corrosion at the terminals.
Received battery a day early! It was charged and ready to install that same day. And to boot the customer service was awesome!
Battery arrived on time and no damage. Voltage was good to go for installing. Really like the free shipping!
Why anyone would buy a Gill non sealed battery is beyond me. This is 10x the battery for about $100 more. And... it doesn’t leak acid inside your 100k investment. A no brainer
Just bought my second one. First one still going strong pushing 8 years but in light of some unrelated age concerns I chose to be cautious. Ol Pink (3 in 4 yr) left me high and dry on several occasions. Just get the battery AND the BatteryMinder charger!
This platinum series battery from Concord RG35AXC is a solid performer in my Mooney F model. I have a SKY-tek starter installed and this battery gives solid starting power. Like other commenters I started getting 2 yrs out of the Gill batteries and I was fighting some corrosion with the wet cells. I had used Concorde before the Gills and got 5 yrs out of the wet cells. So in March 2011 I purchased this upgraded Concorde battery and Im so glad I did. It just started weakening several months ago (in Aug 2017) so I did not want to go into winter and risk getting stuck due to a battery issue. So, am replacing it after 6.5 years. Thats right...6.5 yrs. It has the highest CCA in its class and it has never shown signs of corrosion. Note: I have kept a low amp AGM automatic charger on it during periods longer than 3 weeks and colder winter periods. Perhaps this has helped??? I should note that the Gill tech staff has been very helpful and knowledgable in my past conversations w them.
Simply the best aircraft battery on the market right now. Shipping was free and still arrived in only three days.
Awesome battery, upgraded from Gill, the difference in CCA spin up the big 3 blade prop way faster. Love not having to worry about acid leaking.
I have owned my Cherokee 235 for almost 20 years now and was replacing the battery every 2 years. I purchased the XC battery seven years ago and just now replaced it. My plane was still starting but it showed signs of getting weak when starting in temps in excess of 105 degrees F. Best battery I have every had.
I got this battery to replace a four and a half year old 35AXC. This is now my third one, and the two previous ones had good service lives.
My last RG-35AXC Lasted 5 1/2 years in my Beechcraft V-35-B in the extreme Florida climate. Still working OK when removed. A super product.
This is the only battery that I will use now in my R44 helicopter. The basic R25 just wont do the job... I installed a new battery and a new starter before reverting to the RG35AXC.... twice the cold cranking amps... it rips!
Excellent performer.
Nominal voltage was over 12.5 volts, allowing for a quick change then placing the battery into service, with no lost missions for the customer.
Very good service and arrived in 2 days.RG35axc replaces the same battery after 5 yrs. of use. The old battery tests good but flying to a remote area and one less thing to worry about.Also use a Battery Tender Plus to keep it charged .Only problem is have to modify battery box cover as it wont fit the top of the battery I fly a 68 C177.
Bought a new Concorde RG-35AXC (June 2017) to replace the one in my 1976 Cessna Cardinal 177FG (180HP). The previous battery (also a RG-35AXC) had been installed back in 2009! Any battery that last 8 years is a 5-star in my book. The new battery turns the prop over extremely fast, am very pleased with the performance and super high quality of this battery.
Used this to replace a pink in my new-to-me plane. The pink wouldnt crank the engine, and had issued with the radios. Concord sealed batteries have always been good for me, in my planes and the planes I work on. Worth the price difference in just not having to carry the jumper cables!
Bought this battery based on fedback from various forums and other sources. Only time will tell if it is deserved or not. I have a relatively good experience with a previous flooded Concorde battery which I got 6 years of use. Shipping was fast and efficient. My experiences with Aircraft Spruce have been good. I use them often.
Great battery. We replaced it with an identical make and model. We got 5 years and 378 Flight hours out of the last battery and I was very happy with its performance and reliability.
Did what it advertised, was delivered promptly and well packed, fits fine and starts the aircraft nicely. Lets talk in 3 years since thats the real test.
There may be others less expensive but none are as powerful and efficient as the Concorde RG-35AXC
Excellent battery. With periodic maintenance it lasted seven years in my 180 in the high heat of Texas. I hope to get seven years out of my new one.
Fantastic product! Just bought my Second Concorde AGM battery from Aircraft Spruce, I have used them in two aircraft that i owned. I have changed them out after 8 years. They had not failed yet, but did have diminished capacity and were abused with the wrong chargers.
You can not beat a sealed Concorde Battery with extra cranking. Ive had them go 5 years for me.
Best batteries ever made. If you are bored and like to clean battery boxes or pull your battery out every week to charge, dont buy this battery, look to Gill.
This battery was in my plane when I bought it five years ago. I dont have it on a trickle charger, nor do I know what the optimum voltage my generator should be feeding it is, much less what its getting. Still, its never left me stranded, and the battery box looks brand new. Im only replacing it now for my own peace of mind. I used Gils in my previous plane. I was lucky to get two years out of them, and I was constantly cleaning out the battery box.
Finally a sealed battery that works and does not seem to fail after a year or two like the old ones did. I run a maintenance shop and have been switching customers over as needed to this battery. Some planes tend to boil batteries over causing severe damage to the belly and structures. This battery not only works well, has a very low self discharge rate and, extra capacity, it does not boil over. So far, well worth the extra money over the standard batteries.
Have given zero problems in 5 1/2 years, first thing I bought for my Bonanza and going strong
This is the best battery ever created.!!!
I am just now replacing the one I put in 11 years ago in my Twin Comanche. The pink batteries I used to used lasted 3 years maximum. Pretty much explains why I like it. I especially appreciate the fact that these batteries completely eliminate the need for battery box maintenance. No more cleanout. No more baking soda. No more messy battery box paint.
Just received and installed in my light twin. I have been plagued with hot start issues. I've installed bogart cables, sky tech starters, and alternator conversions.. Better, but performance still lacked. My Gill battery finally gave up after 2.5 years. I decided on the AXC for the few extra cold crank amps, I do not regret the extra $30. I am finally satisfied with the starting performance.
Bought one in 2006 and now 8 years later it is beginning to show signs of weakness. It has never left me stranded and I keep it on a trickle charger when in the hangar. A great product. I'm buying another one.
Wonderful battery. Combined with the correct BatteryMinder charger/maintainer I have gotten five years out of this battery and it still passes the ICA. The cost is comparable to a flooded battery, plus free shipping. I put an EI VA-1 volt/ammeter and Zeftronics ACU with OV and ground fault protection in the plane and set the VR for summer and winter voltages per the owner's manual. So far so good.
Wonderful battery that has never let me down. Never, and my first one was badly abused charging with car chargers and depleted to below end voltage on a long flight with a dead alternator. That battery still lasted five years before a cell died. It still started the engine just fine, but it would not pass a capacity test. Nine years later it is still good enough to run the 2000 lb hangar winch once in a while. Along the way I set the ship's alternator to the owner's manual recommendations for summer and winter voltages (14.2 - 14.4v for my average temp). It is also babied because I use the VDC BatteryMinder 12248-AA-S1 and now the -S5 charger/maintainer continuously when the plane isn't flying. I also have a solar charger from VDC for when its parked on the ramp somewhere. The thought isn't to save money: It's to have a reliable battery. The second battery is just turning four years old and still passing the Concorde capacity test. It has been babied more than the first so I expect it will last longer than the first, which beat the competition by about 2x at a similar cost. A word of warning: AGM/RG batteries do not tolerate abuse as well as flooded. Boil a flooded and you can refill it. Boil an AGM and it's toast. Ditto undercharging. To get max life you have to be a bit anal.
Concord a good battery but priced more than double what its worth, thus helping to destroy general aviation.
Concorde Sealed Battery RG-35Axc
Concorde Sealed Battery RG-35Axc
So far so good! Seems to be a good strong battery. Time will tell. Replaced a conventional Gil. Note the size is a tight squeeze into my battery holder. Height was about an inch higher, so required longer hold down bolts.
I really like Concorde batteries, although I don’t seem to get really long life from them. I’m averaging about 2 years.
This is my 4th or 5th Concorde 35 AXC. Most last 4-6 years. One failed prematurely in flight.
Prompt service. It works as advertised. Expensive.
Had trouble with ordering process but they corrected problem. Otherwise would be 5 stars. Good product, fast delivery.
My 3rd 35axc. First one went 5years so I replaced it and it’s still going strong on my Polaris Ranger. 2nd one failed at three years. Disappointing but it happens. I have high hopes #3 will be a 5year battery.
I have a C182 and it started this engine very well. For the money you would think it would last longer that 2 years, but it worked well til it died.
Great battery, but only lasted 3 years in my Bonanza. We have a nearly new Plane Power alternator STC, carefully set to charge at 14V
I have used the Concord Battery for many years and they typically last 5+ years. The RG-35AXC purchased in 2023 lasted one year. Spruces customer service was excellent however I only recieved about 50% credit for warranty. I hope the replacement will last 5 + years.
Concorde Sealed Battery RG-35Axc
This battery does not fit in my 1973P Cessna 182, the battery box lid will not close properly.
My Concorde RG-35AXC died after 4.5 years. Im a little disappointed about that, given its price point compared to the competition and the reputation of the company and its products. Nevertheless, Ive ordered the same replacement battery as its still the best battery for my airplane.
The shipment was in a box of no indication of this side up I was placed on my porch with the battery upside down. Fortunately, it was well packed and the battery is sealed. It is working well. Suggest this type of shipping be marked woth a this side up or equivalent.
Dont ever fly with this battery in a discharged state. It will play havoc with your electrical system. I lost my ammeter - smoked it before popping the 60 amp breaker. Make sure this battery is fully charged and keep it that way. These things dont function like your typical auto battery that seem to tolerate such conditions.
Doesn’t fit very well with my battery box lid!
Concorde Sealed Battery RG-35Axc
I wish my experience was the same as many here. I purchased this battery from Aircraft Spruce 10/4/17. Now (7/11/19), approximately 20 months later, its dead. Replacing with same and hoping for better results.
This is a replacement for the same battery that only lasted one year and less than 30 hours of tach time. It would not hold a full charge and had a bad cell on one end that gets warm when charging. Currently waiting on a warranty claim.
Expensive and only lasted 3 years then completely kaput. It has been on the same battery minder my previous battery was on. The Gill lasted twice as long.
The battery doesnt hold charge well. The older concord 35 held up for nearly 10 years. This one wont make a year. Dont waste your money with this new design.
Nowhere near as good as the last one. Never had the cranking power and would go dead if sitting for a couple of months.
Battery failed in 20 months 100 cycles. Correct battery minder in use, no unusual environmental conditions (Virginia) or equipment (Cessna 180). Concorde advised that credit under warranty would be $50 +/- for a $340 battery. They sent me to Aircraft Spruce as distributor, who has a warranty card on line with no mailing instructions so I have to wait for someone to call me back with mailing instructions! This isnt my first rodeo. Been flying 50+ years and owned all or part of seven airplanes over than time.
Upon receipt was placed on BatteryMinder S5 and charged according to instruction sent with battery. Battery was then removed from charger but not installed. It was checked with battery tester and revealed 10 volts. I am have completed the warranty card as instructed and am waiting for a replacement.
I have RG-35AXC in C-182. It was installed 2 years ago. It is dead. The ac starter turns max 30 degrees the prop after full battery charge. Im very unhappy with this battery junk.

Yes, this is a drop in replacement for this aircraft. 1) We maintain the charge in the batteries while they are in stock. A volt meter is a good way to determine present state of charge. 2) Please do pay special attention to avoid over-torquing. Torque information comes with the battery. 3) You need to contact the local FSDO for this question. per the manufacturer, we have an STC and PMA. The STC is available at no charge. Per Concorde, they just need the information sheet completed and they can can email for free. 4) Some installations do require modification of the battery box cover. This is covered in the STC. 5) We only recommend the BatteryMINDers listed under the "Accessories" tab of this web page
No, trickle charging this battery should cause any harm to the battery.
There is a form that is available in the "Documents" tab. It is the first one listed. Please download it, fill it out, and send it to Concorde and they will send the STC at no charge.
The cold crank amps rating is 440.0.
Concorde recommends the battery minder part number 11-07739 for charging, this is an 8 amp charger.
Yes, they are the same size.
Yes, the application is the same for both RG-35A and the RG-35AXC. The XC model is extra cranking and provides the highest cranking power and capacity in the 35 line. It is commonly used in cold weather applications.
Please see the link for the "Download RG-35AXC Diagram" in the 'Overview' tab of the web page. The dimensional drawing is included in the PDF.
The cold crank amps rating is 440.0.
Yes, per the application chart, the RG-35AXC should be the correct battery for your aircraft.
No, it is not considered haz-mat for shipping.
Yes, the FAA Approved applications are the same for the RG-35A and the RG-35AXC so they are interchangeable as replacements.
Yes, this will fit the M20F.
This battery would not be a direct replacement for the g-243 as it is 14v and the 243 is a 24v. The Concorde replacement would be a n RG24-15.
Yes, the RG-35AXC fits the same applications as the G-35.
Yes, this will fit the Beech Muskateer. XC stands for extra cranking. Otherwise the batteries are the same.
