Clarion is not Johnson Controls.
Interstate batteries were made by Johnson controls until around 2018.
Wanting to get into other things Johnson Controls, who at the time had a contract to supply Walmart batteries, sold their lead acid division to Exide, who at the time no longer made batteries after a bankruptcy some years prior got them out of the mfg. of batteries. Exide bought the rights to the name not the location or the plant.
Batteries now made by Clarion, the division brand that took on Interstate, and various OEM contracts, including Motorcraft and AC Delco, makes its batteries at various locations, some in Canada, and in various other plants around the world.
They are not the same battery that was being made by Johnson Controls and the country of manufacture can vary but location and battery group or size.
I did buy an AC Delco battery for my one truck and so far it seems fine but they no longer come with long warranties, the warranty for a wet type lead acid battery, which most vehicles are designed to charge, is 3 years. The longer warranties are on AGM types (Absorbed Glass Mat). These don't always do well in an older charging system as they require a different charge rate.
From what I'm seeing, at least on the east coast, the only battery company still making a good solid old school lead acid battery here is East Penn in PA, the makers of Deka, Federal, some Diehard and some Napa batteries.
For a bit, when Interstate first sold, we saw some East Penn batteries sold under the Everstart Maxx name. I've got two in my diesel truck and so far they've lasted two years longer than any batteries before them.
Batteries at my local Walmart have various origin countries on them, I've seen Mexico, Canada, Israel, Austria, Taiwan, Malaysia, and China on various batteries but in the last four years, since the pandemic, battery inventory at Walmart has been almost non existent. Which is why I ended up buying the AC Delco battery for my gas truck.
I was there last week and they had about four batteries on the rack and none were common sizes or anything that fit any of my vehicles, but the whole store lacks inventory and they blame it on 'Supply Chain issues" but a Walmart 12 miles away is fully stocked, as are all the other stores.
