After using my first PC680 in my RV-7A for about 5 years, I've only managed to get an average of 2 years for each of the next 5 batteries. I haven't used any battery tender or trickle charger. At the EnerSys (manufacturer of the PC680) booth at OSH, I discussed my experience by asking him if the the manufacturing process had changed. He said it had not and sounded genuinely interested in what he thought was my lackluster experience with the more recent batteries.
I gave him this forum website so he could checkout the PC680 comments himself. And I encourage any of you currently at Oshkosh to seek out the EnerSys booth in Hangar A 1042 and share your experience with him.
