OPTIMA® BLUETOP® BCI D31M group 31 batteries are our most powerful and have the largest energy storage capacity. Usually they can be mounted anywhere a (slightly shorter) group 27 would be used. Ultra high-performance SPIRALCELL TECHNOLOGY® AGM (absorbent glass mat) dual-purpose battery for marine and RV. BLUETOP® has three times the cycling capability (rechargeability) with ultimate cranking power for your boat or RV in a maintenance-free package. Perfect for multiple high-demand accessories and trolling motors with 15 times the vibration resistance and lighter weight. Lower internal resistance provides more efficient power output and faster recharges.
