We get Motorcraft and AC delco from a Deka delivered factory truck every Wedsday. Then he's headed to Walmart, Advanced, Autozone, Sears, and Sam's. I learned this some years back when I went to Deka factory. But let me say some companys that buy from the big 3 put some extra plates in there batterys. Such as Catapillar. Hope this helps.
Interstate is a reseller and has never made batteries. A lot of theirs are made by Johnson Controls who also owns the ACDelco brand for batteries and makes Motorcraft and Everstart as well.
