Sometime ago I found Johnson Controls is the manufacturer of a whole selection of batteries that are offered rebranded on retail (SEARS, COSTCO, WALMART, AUTOZONE) and Johnson controls makes some or all of these batteries as well: Acura, Advance Auto Parts, Autocraft, Western Auto, Tough One, Alliance, American Hardware, Ames, Varta, Blains Farm & Fleet, Battery Alliance, Bosch, Carrefour(Europe), Champion, Amara Raja Batteries LTD(Joint venture with Johnson Controls India). Varta, Optima Batteries, LTH, and Heliar are all battery manufactures owned by Johnson Controls.
Johnson Controls also supplies OEM Batteries to Ford Motor company, Daimler Chrysler, Honda, Toyota, Nissan, and Isuzu.
So when I needed a battery I went to 3 or 4 stores and I verified the recommended battery models, What I can tell you is that they were the same battery with different labels, same enclosure, same terminals and of course same manufacturer.
Finally I got the brand that offered me the best warranty/price, If you decide to buy one of the above brands, Just get the top of the line of any brand, they will probably be same battery, Just try to get the best price and the best warranty possible.
