I installed a Gill 35 series in my 7GCBC, had never failed to crank until Katrina was on top of us, believe it or not had to get the wife to hold the brakes while I hand propped it to move to safer ground, thats another story. After the storm I didn't fly it for several weeks because of having to try to repair fence and other storm related damage, but to make a long story short when I did go to fly it the battery was dead, talked to Gill, these batteries are not for occasion use they need to work regular, also high temps are not good on these batteries either. Gill made the battery good and I went back with the wet cell battery. That was just my experience with the RG series battery.
