That might be old news
I crawled down the rabbit hole some, the $55 dollar "made in Mexico" Wal-Mart batteries were really sweet, likely a top shelf Johnson controls battery with a cheaper sticker
The $55, 75 and $125 battery were identical, minus the sticker, warranty, and price
The group 65 battery was stickered at 650cca and consistently tested at 895cca plus. Now they are made in south Korea and test at 774-5cca
I'm still buying them for beater trucks
