Hello Gang; I don't really want to start a big debate over this but this is what one dealer told me. If you buy a name brand lead acid battery, of a given amperage, the only difference between the more expensive ones and the cheaper ones is the type of warrantee, the quality is no different. The more expensive ones don't last any longer but they have a longer free replacement period and a larger credit on a new battery after five years. So pick a good name brand, like Interstate, get the one with the largest number of cold cranking amps, and buy the battery with the basic warrantee. Then again you could find a place like where Kenyon buys his. Best Regards Arran Foster 1954 Imperial Newport Needing A Left Side Taillight bezel and other trim parts.
