ATS AWD Luxury Turbo
Battery quality for most brands run in cycles (God that was bad) :vomit: . Objective test houses give a new number one rated battery about every year. For many years the top of the line Die Hard rated #1, then the Interstate and Delco. The truth is, only a few companies make batteries, and normal spec and manufacturing variations do make a difference. I wouldn't even guess who makes the best at any given time. If you shop the top of the line batteries and use warrantee as the tie breaker you probably can't go too far wrong.
