Product Overview

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

L Terminal AGM Batteries are great in both deep cycle and starting applications. They charge more quickly than conventional batteries and have low 3% monthly self-discharge rates. The spill-proof, valve-regulated design eliminates acid spills and terminal corrosion. AGM batteries are safer to operate than conventional flooded batteries, as the chance of explosion or acid spray is reduced which allow them to be installed in almost any location and any position (except upside-down).

Manufactured in the U.S. for West Marine by East Penn, one of the most reputable battery companies in the country. Each battery receives over 250 quality control checks to guarantee consistent and superior performance. East Penn’s award winning factory leads the industry in closed loop and sustainable practices. Nearly all of the plastics, lead and acid are recycled, so our batteries are great for your boat and the environment.
