Standard 'vette convertible. Only 40k miles and nothing too special in terms of options. But, I've just installed the fourth battery in four years. Each spring the battery is completely dead though I try to start the car once or twice a month during the winter. It's garage kept, dry, and rarely does it get too cold in the garage. This last time I couldn't even "jump" it on the full 100 AMP charger setting.
AAA loves me. The repair shop that keeps putting in new batteries under warranty hates me.
Climate control is OFF. Key is OUT of the ignition.
What could possibly be the problem her?. All the shop tells me is "you have to drive it because we can't find anything wrong."
Thanks.
