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.
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.
