I've been running the same Optima YT in my Caprice for years now without issue. I've drained it a handful of times. I keep it on a charger during the winter months. Is it that much better than any other battery? Probably not. Have I had issues with it. Yes, but it was my fault. You're not supposed to use a 70 amp quick start charger on a deep cycle battery; they're designed to charge slowly. Was the warranty service fast, friendly, and not full of questions? Yes. They swapped it out due to a "manufacturer's defect" that really wasn't a "manufacturer's defect." Would I buy one again? Probably not. With a house, a kid, another kid on the way, two Jeeps, my Caprice, and a wife ******* all of my income, I have to be smarter with my money than I was a few years ago. I'd probably get a Diehard Pt.
