“It might be noted that Wal Mart batteries are manufactured by Johnson Controls. . .” I’m not sure this is true nationwide. I think I bought a battery from WalMart that was made by Delco. A friend of mine went to an independent battery store and the battery had no label. When he asked about what kind of battery he was buying, the proprietor opened his desk draw displaying all kinds of battery labels. He asked my friend, "What make battery would you like it to be?'
Batteries are heavy for their size and are expensive to ship. Often, batteries in different parts of the nation are made by a major manufacturer such as Johnson Controls, Exide, AC/Delco etc. and a different brand name appears on the battery.
