No, when I bought my enclosed car trailer, it already had a blue top Optima battery init, for running the winch, electric tongue jack, and 12 volt lights. I thought that my winch operated kinda weakly, and trying to charge the Optima with my "normal" battery charging accomplished little. Went on the Optima website, and discovered that standard charging practices do not work with Optima batteries. You either need to buy one of their $$$ Optima brand battery chargers or have an extra normal 12 volt battery to connect to the Optima, and then connect my battery charger to the wet cell battery. Since my trailer battery is rather hard to access, it was a pain to hook it all up like that, but even after doing so, the winch seemed a bit weak. Took out the Optima, installed a regular deep cycle battery, and no more problems. The winch works much better now than it ever did with the Optima, for about 1/3rd the price. I have also had very good service from DieHard batteries, 15 years out of the DieHard in my 74 F350, my 99 F350s DieHard is only 4 years old, but it cranks over the V10 with ease, even after sitting in the truck outside all winter without needing a charge.
