Try a search on this site. There have been a number of recommendations in the past few months.

Batteries like Interstate, Sears DieHard Gold Series come to mind. Johnson Controls Optima batteries are a completely new animal.... last a long time but cost the most of any battery.

Someone posted that the Sears Gold series is actually a different (and better) battery than the other stuff they have on their shelves.
