Does anyone else have issues with batteries holding a charge? I've went thru 4 optimas in the past 5 years. Biggest problem is I don't drive my car often or at all some years but no matter if I unhook the positive cable from the battery and or put it on a tender or its hooked up seems like whenever I wanna drive the car the battery is dead and a cell or 2 in the battery are shot. I don't get it. Same problens if it's a month or 6 months. It's like something in the car is destroying the batteries ?!?
