Replace your flooded batteries with an Absorbed Glass Mat (AGM) battery built for boaters who want more power, more reliability, and less maintenance. This Group 27 dual purpose battery delivers high cranking power for fast, dependable starts along with moderate deep cycle capacity for running electronics and accessories between charges. The sealed, valve-regulated design is spill-proof and safer than conventional flooded batteries, with a much lower risk of acid spray or explosion, so it can be installed in almost any location or position on your boat (except upside down). AGM batteries also accept higher charging current and charge faster than flooded batteries, with a low 3% monthly self-discharge rate that keeps your battery ready even during long stretches at the dock.

Built by East Penn: manufactured in the USA for West Marine by East Penn, one of the most respected battery makers in the country. Every battery passes over 250 quality control checks to guarantee consistent, dependable performance, and East Penn's award-winning factory leads the industry in closed-loop, sustainable manufacturing, recycling nearly all of its plastics, lead, and acid. That means a battery that's better for your boat and better for the environment.
