Each Lead-Acid battery comes with a Material Safety Data Sheet, also known as a MSDS, and it will list, in code, the name of the company that produced the battery.

But this will tell only a part of the story, because the level of quality will vary from one private brand to another.

I have had poor results with batteries from WalMart and good results with batteries from AutoZone, and yet in my part of the world both brands are made by the same company. However, the difference in the level of quality is obvious.

For this reason I tend to buy based on service and quality. If a WalMart battery fails it is incumbent upon myself to remove it and carry it in for replacement. With AutoZone they come out to the car, test it, and install it.

As for K-Mart I have not been in one in over 15 years, so I don't feel qualified to speak on the subject except to say that I have not been in one in over 15 years. Perhaps that should tell you something of my opinion on them.
