Great battery! I have them in two of cars, but their shape and spiral cell design means they do not have the energy density of rectangular case AGM deep cycle batteries. The biggest Optima is a group 31. It weighs 60 lbs and has 75 amp-hours of energy. The Trojan group 31 weighs 67 lbs and has 100 amp-hours of energy.
