I've had good luck with several Costco house-brand batteries, which for some reason I think are made by EverReady, or at least were back when I bought them. I like their price and their no-nonsense attitude about honoring warranties. That having been said, I've also got an Interstate and a pretty old Diehard in the family fleet.
Remember to not only choose the correct battery, but also keep the terminals on the charging circuit clean and tight, and make sure they're well charged. That, plus correct choice of ratings, may be more of the game than choosing the "right" brand.
Charging-related matters are especially worth some attention in the winter, when those lights-defroster-and-low-speed commute slogs tend to challenge the alternator's ability to keep them charged.
If shopping for a new car battery right now, I *would* be tempted to try one of those completely sealed, spiral-wound Absorbed Glass Mat jobbies. They seem to have both electrical and mechanical advantages over the traditional kind.
Lots of good stuff (some of it related to non car applications) at
