12 Volt AGM Sealed Valve Regulated Non-Spillable


Marine AGM batteries are specially designed for engine starting and the long deep discharges typical of marine applications. The maintenance-free AGM* design immobilizes the electrolyte making them spillproof and leakproof, so they’re safe to use no matter how much your tiny ship (or luxury yacht) gets tossed. They are available in all popular marine sizes with abundant cranking power for quick, easy starting and all the reserve power necessary to keep your auxiliary equipment running strong.
