Best battery ever. I installed one in a customers Piper August 2010, was kept on a Battery Minder and after 14 years is still passed the capacity test. Same battery in my Cessna 182 passed capacity test for 7 years, but kept on working. Only had 2ea Concord failures in over 20 years.

Mike J Verified Purchase

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.

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.

Great product and service from Spruce! . Made a huge ruin performance. Plane runs smoothly. I replaced REM38E with theses Tempest UTEM40E. CHT doesn’t run hotter like I was concern. Much cheaper the the Champion and does exactly same thing. You pay Champion extra for the bran name.

Joel F Verified Purchase

GILL SEALED BATTERY 7035-28

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.

Paul W Verified Purchase

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.

Peter Z Verified Purchase

CONCORDE SEALED BATTERY RG-35AXC

I ordered this product as a replacement for my G 25 lead acid battery. I had to return it, it was not a direct replacement. It was 8 pounds heavier, and almost 2 inches longer, and would not fit on the existing battery shelf. other than that, I like the idea of it but unfortunately I was not able to use it.

John E Verified Purchase

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.

The new battery is working fine. Sadly, the previous one from Concorde cost much less. That one lasted about 7 years.

Michael R Verified Purchase

CONCORDE SEALED BATTERY RG-35A

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.

William A Verified Purchase

CONCORDE SEALED BATTERY RG-35AXC

I ordered two of the same sparkplugs , when I checked them, one of them had a gap a little tighter than I wanted , I was able to adjust but it would be easier to close a larger gap than one you want to open . Thanks Joe

TEMPEST SPARK PLUG UREM40E

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 batteries are excellent and their factory support is top shelf. I ordered this particular RG35A to replace an identical unit that held up well for 7 years. Not too shabby.

TEMPEST SPARK PLUG UREM40E

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.

Earl M Verified Purchase

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.

Henry K Verified Purchase

CONCORDE SEALED BATTERY RG-35AXC

This same battery lasted a terrific 63 months. Granted I ran it down a couple of times but also took care of it with the Battery Minder charger for with desulfation circuits calibrated for the Concorde battery. Reliable pair.
