Product Overview

A great battery for your house bank or 12V or 24V trolling motor

Lead-calcium batteries deliver more power per pound than competitive dual-purpose batteries. They feature a no-spill design that allows you to heel over to angles up to 45°. Connections are made easy by the “L” type terminals.

For marine uses, our 6V deep cycle flooded batteries are best when wired in series to build banks for 12V—36V applications. These batteries are workhorses; their larger capacity provide the amp-hours needed to be away from the dock for longer periods of time or run your trolling motor for the day.

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.
