Nice find.
I don't see much value in this as far as who made your favorite brand of battery. An Interstate, for example, might come from 10 different sources. And I don't see a way to narrow it down for a specific battery size or model.
The contact info for all those manufacturers is worth the price of admission. I've often read how there are only about 3 battery manufacturers, which obviously is bunk, unless you limit the statement to USA sourced. That part usually gets left out of the discussion.
I also take issue with the assumption some make, that two battery brand names, which may come from the same manufacturer, are necessarily the same construction. Battery manufacturers can and do make batteries to any spec and price point you want. All it takes is sufficient quantity. There is no reason to assume it is just a different label on the side.
