I've got a Sears Diehard that's been in there for 4 years, I think it was in there for 2 years prior too from the previous owners. And it still cranks strong and I've even left the dome light on for 24 hours before and it didn't make a difference.

Nice to have the huge batteries these cars are equipped with eh.
