I have been using this battery for about 4 years, yes 4 years. It is still not showing any signs of tiring out (knock on wood). The great thing about this AGM batteries is the no spill no corrosion thing. I used to get corrosion on the terminals all the time, I have gotten none with this battery. Couldnt recommend it more. It is in an enclosed battery box that is very well vented to the outside because of the old regular serviceable batteries, so this could be a contributing factor to the lack of corrosion.

Aircraft spruce recommended this over a standard G25 Makes sense in the dry arrid climates of the southwest Also great price and fast shipping !!

Had two g25s before. This is upgrade. Take charge from generator much better. Other two failed at 1 year and at 5 months. This was Gill suggested replacment. Gill replaced second under warranty. They were great to deal with. Aircraft Spruce support a little weak.

Excellent service

Great battery, I much prefer the sealed batteries. The delivery was super quick.

Good product. Fast shipping.

I am very pleased. It matched size of the old G25, fit right in the box and cables attached perfect. As expected. The ordering and delivery were fantastic, quick smooth and easy. thanks

Battery has been good for 4 years. Only on the last start attempt did it not have the juice to start the engine. Charged the battery up over several days registering 13.4 Volt. Let it set for a week due to weather conditions and when I went back out to fly, the battery would not kick the engine over. Still I ma pleased as it is the longest service I have gotten out of an aircraft battery. The AGM is also great as it did not leave any acid residue and absolutely no leakage problems.

I gave it four stars because I just dont know yet. I had a Concorde battery in the Skyhawk and it failed miserably - and right at the end of the warranty. Unfortunately, Concorde just prorates the batterys life over the two year warranty, so replacing with same would have still been more expensive than buying this battery. As far as what I can tell you about the Gill... first, I like the fact that the battery tightens up with the wing-nuts on the top post. Makes servicing in the field easier. This battery also has a handle! Doesnt sound like much, but it made dropping the battery into the aircraft considerably easier than with the Concorde. Battery was fully charged and provided a robust crank to the Skytec starter! That was the thing I wanted it to do. Will see over the next few years how well it holds out - but at almost $100 less than the Concorde, if I get two years, I have a better value going.

It works!

Packaged well, received in a very timely manner. Works great.

received promptly and in good shape

I like the cost and they work great.

This is a very good battery. The fit was perfect and the install was routine. The only reason I give this 4 stars is the charging instructions. I received it very quickly. It came a bit less than fully charged and I did not find this unusual. I followed the instructions for charging. However, the instructions indicated that the battery should be charged at a voltage more than 14 VDC. My charger outputs 13.6 vdc max. After charging the voltage on the battery came up to 13.6. My airplane started perfectly after installation.
