The M24 is a dual-purpose marine battery designed for both engine-starting and deep-cycle applications. Delkor’s advanced lead-calcium technology provides many benefits, including improved resistance to corrosion, overcharging, gassing, water loss, self-discharge and thermal runaway, all of which limit battery life in conventional lead-acid batteries. The M24 features:• Factory heat-sealed covers prevent contamination and increase casing strength• Denser active plate material for improved cyclic ability• High cranking power• High reserve capacity• Ultra low water loss- liquid gas separator• Low- resistance envelope separators
