Johnson Controls also makes batteries for Interstate, Die Hard and Optima, although Optimas quality has gone in the toilet since moving their manufacturing to Mexico.
Used to be a HUGE Optima fan, not so much these days.
Anything made by Johnson Controls are good batteries for sure. ('Cept Optimas)
I would highly recommend getting a deep cycle of whatever brand you buy, money well spent.
Northstar batteries is a fairly recent upstart company that looks to be making some VERY good batteries for very reasonable prices, well worth a look for sure.
That's what I'm going to try when my last Optima gives up the ghost.
