whats everyone doing for car batteries these days??

Duracell/East Penn for me. I have one in all my vehicles. I doubt the oldest one is more than 3-4 years so can't say how they compare to the Johnson Controls batteries you get everywhere else but I just can't stand giving my money to gigantic corporate conglomerate pseudo-monopolies. Prices are pretty good too and I like Batteries Plus, it's a nice store with knowledgeable employees.
