Group 8D Dual Purpose Marine AGM Battery, 245 Amp Hours, 1450 Cold Cranking Amps, 1,800 Marine Cranking Amps, 480 Reserve Minutes

Replace your flooded batteries with Absorbed Glass Mat (AGM) batteries. They’re more rugged, accept higher charging current, are sealed, safer, and submersible.

When you're out on the water, your battery can't afford to be a weak link. The West Marine AGM Group 8D Dual Purpose Marine Battery is built to handle both high-power engine starts and sustained energy for your onboard electronics, all in a sealed, spill-proof design that's safer and tougher than any flooded battery. Whether you're pushing through choppy swells or anchored out running a full electronics suite, this battery is engineered to keep up.

Absorbed Glass Mat (AGM) technology gives this battery a serious edge over traditional flooded batteries. The glass mat separators hold the electrolyte in place, eliminating acid spills and terminal corrosion while making the battery fully sealed and submersible. It charges faster, holds a charge longer with a low 3% monthly self-discharge rate, and delivers reliable power season after season. You can mount it in virtually any position and almost any location on your vessel, giving you flexibility that flooded batteries simply can't match.

Built for the demands of offshore and coastal boating, this Group 8D battery is rated at 1,450 Cold Cranking Amps (CCA) and 1,800 Marine Cranking Amps (MCA), with 245Ah of capacity and 480 reserve minutes. It's designed to crank large engines confidently while also powering fish finders, chartplotters, radar, stereos, and other accessories without breaking a sweat. Rated for 300 cycles, this battery is made for the long haul.

This battery is manufactured in the USA by East Penn, one of the most respected battery manufacturers in the country. Every unit goes through more than 250 quality control checks before it ships. East Penn's award-winning facility operates on closed-loop, sustainable practices, recycling nearly all plastics, lead, and acid, so you're making a responsible choice for the environment without sacrificing performance.
