Never have had a bad Interstate battery. Optimas though. went through a half dozen in some cars around the shop in about 2 months. Kept exchanging for new Optimas but gave up shortly after and run AC delco or Interstate.

 

Ive wasted money on 3 Optimas before I went back to a acid celled battery. Im running two uralast gold batteries now and no issues.

 

Thanks for the info guys. im really surprised about all of your Optima opinions... So no one has heard about braille batteries? im gonna cross those off the list though, $300 on a batt is crazy when that $300 can go into other mods. If I win the lotto i will be all over it, but for now im good.
