Installing an OPTIMA BlueTop in your boat or RV means more running time, faster recharge, and up to twice the life of a traditional battery, which leads to one thing - more time doing what you love. The tightly wound construction in an OPTIMA minimizes plate movement and subsequent damage caused by harsh conditions, extending battery life and taking away the need for RV hook-ups. Who knows, staying out on the water longer might actually increase your chances of catching that trophy fish.
