Two Interstates in mine.

Yes Johnson Controls makes many of the batteries sold in the U.S. including many of Interstate's batteries. However those batteries are made to the seller's specifications which can vary.

My truck is a 2008 that sat on the dealer lot for a year. They had to jump it when I test drove it. Those batteries did not last very long and they were replaced at no cost to me. The replacements were Interstates with Mopar stickers on them. Last year I replaced those batteries with Interstates even though they still worked and would start the truck even after it sat for a few weeks.
