I'd recommend something else. DieHard Platinum is also built by Johnson Controls (well, we can't really blame Johnson Controls, Optima is a subsidiary) but is of far superior materials and quality.
Optimas are disposables, even in their own eyes. I went through two... they're local company so I spoke to them about replacing the first one. They refused, the second time I just went to Sears and had them bin the Optima (ask some experienced auto techs, you might find that they fail a lot more than you think).
High quality and cheap never go hand in hand.
