Unleash the Banshee this year with the new Group 31M deep-cycle marine battery with dual terminals. Banshee batteries are designed to withstand rigorous deep charges as well as long slow recharges. The Banshee marine deep-cycle battery is a direct replacement for Optima D31M batteries and guarantees excellent recharge capabilities for long-lasting performance.

Banshee marine batteries are produced and manufactured using only the most up-to-date materials. All Banshee group 31 batteries have a built-in Hydrometer which easily tells the current state of your battery life and is completely sealed so there is never a need to add water. Our group 31 marine battery is rugged, powerful, resilient, and should be the only battery you rely on for cranking, igniting, and lighting.
