Well might have to add another $120 or so to the money pile. I bought a New Optima battery for the Stang about two months before it broke. Well It has sat in the car for about 4 years now. I know I have had to have it charged a couple of times due to it being drained. I let Autozone charge it yesterday and went to pick it up tonight. 12.91volts at first, under a load it dropped to 8.31 or so, I knew it might not be good. It said charge and retest so hopefully another trickle charge overnight cures the problem, but I doubt it. I have had another one I have had in 3 different vehicles that is eight to ten years old and still turns over my truck. Just my luck......
