There are basically two or three mass market battery manufacturers. Johnson Controls is one. Between them, they make roughly 95% of all battery brands sold in the US. Buying a name brand may or may not have it's advantages. Price is sure not one of them. Around here we have dedicated battery stores and I have found that the batteries they use, are manufactured by Dekka battery corp and are quite good at a far lower cost per year of warranty than others like Sears Diehard or many others. Do some research as to manufacturers and who makes what. Search for quality and longevity. Personally at least around here Johnson Control batteries are not as good as the Dekka's.
