Deka brand in-house - Top-quality stuff. You can buy 'em at Car Quest.
re check that list. i work for DEKA and we make most of the batteries listed here! walmarts were made by us until a few months ago, but sams club we still make for not sure about costco. we are making sears, autozone, advance auto and many others. johnson controls is the only company in the battery industry bigger then DEKA right now. they make up over half the buisiness exide is only around 7% last time i heard and DEKA is in the 20 some percent area.exide is about gone lol.
