Finally had to replace my 6 year old Concorde RG24-15M in my Archer. It was still turning the engine over just fine and it never failed to get me started but, it did fail its capacity test during the last annual. At low rpm I would get a low bus voltage indication. So, I still used it for a few more months and then replaced it. The new one is really cranking the engine and I no longer get a low bus voltage indication at low engine rpm. I hope I get at least another 6 years out of this new battery.

I initially ordered the battery without the M suffix. But during the shipping process I called in and customer service was able to make the change.. I was very happy that just to be done and it did not change the shipping delivery status

Perfect fit. Charged and ready to go. I had concord batteries before and they have great reserve power and last long.

Replaced a 3.5 yr old Concorde RG24-15M battery with same. Plane resides in very hot southwest FL which hard on batteries. Battery is sealed and did not leak at all.

Used this model to replace a failing Gill battery in my T182T. Fit was fine. You just have to be careful when tightening down the terminals (this batter uses bolts to secure the wires rather than terminal studs with a nut on the Gill). This one has much better cranking amps than the one I replaced. Hoping the Concorde last longer and helps with my hot starts. Arrived in 2 days (free shipping) which was awesome for a heavy battery.

After years of trashing Gill batteries every 2-3 years switched to these and got 7 years out of my last battery in my Cessna 172S.

This is my 2nd Concorde. My first one was 5 years ago and would have lasted longer if I had kept it charged properly. It fit perfectly in my 172N. I agree that it is very expensive but it is a quality battery.

This is the 2nd Concorde Ive bought for my Skylane. The last one was 6-1/2 years ago. I keep it in a hangar on a trickle charger & fly it weekly, but thats pretty incredible life for any battery. These are more costly than the other options, but Im very happy with the cranking performance, quality of workmanship and the long life of these batteries. Quick, free shipping from Aircraft Spruce, too!
