Just get the autozone with lifetime warranty or even better an Optima Gel cell if you can afford it. There are only like three companies that make batteries so it does'nt really matter where you go. Just don't get a Die Hard, they suck now. A buddy of mine works for interstate and he said the same company that makes Die Hard used to make the Autozone Batteries but Autozone switched companies due to a rash of faulty batteries. I have an Optima in my CRX and it's great, I mounted it laying down in the hatch area with a moroso battery relocation kit after reading an article about it.
