In both of my cars I use a Sears Diehard Gold. I have a battery cut- off switch in the one I drive occasionally, and the other one I leave disonnected. Have had no problems for over three years now. I personally have never noticed a difference in batteries as far as Optima VS Diehard. Have used them both. But I always use Diehard because of the warranty and easy return to a Sears store if one fails within warranty. I used to buy cheapo batteries for my "beater" cars, but after dealing with the morons & Wal-Mart & Auto-Zone, I will never buy another battery from them again. Price was good, but they seemed to all die because of a dead cell within 12-14 months, and even though it was dated on the battery, no warranty exchange was allowed unless you had the ORIGONAL receipt. Just buy a quality battery from a reputable store and you shouldn't have a problem.
