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.
