I use whatever is cheapest at Autozone. I've never gotten less than 3 years out of one, and I jump start vehicles all the time. Now, I do no winching, and I never drive upside down, so in those cases maybe the extra cost of an Optima is justified. <img src="/forums/images/graemlins/lol.gif" alt="" /> I usually leave my lights on at least once a month too, and nearly kill the battery. But the drive home seems to charge it up like new. I sure have no reason to spend more than what I do on a battery...yet. <img src="/forums/images/graemlins/smile.gif" alt="" /> I think a dual battery setup would be cool, even if I never used it. <img src="/forums/images/graemlins/lol.gif" alt="" />
