Johnson Controls is a large manufacturer of after market batteries. Whether you buy from Wally World, Costco, or the Sears Die Hard, they are all the same battery from the same manufacturer. Only difference is the labeling. A couple of years ago JCI bought Optima to grab that niche of the market too. Just this week I went to Costco to replace the Optima in my TJ. All my other vehicles are running Kirkland batteries.
