Product Overview

Not just a car battery, West Marine Flooded Starting Batteries are built to last in the marine environment.

Designed to deliver more power per pound than competitive starting batteries, West Marine Starting Batteries feature a no-spill design that allows you to heel over to angles up to 45°. The exclusive molded-in stainless steel studs and hex nut terminals make connections easy, while protecting against corrosion and failure.

Flush top and low-profile flush covers keep the battery top clean and acid-free, making them easy to restrain and eliminating lost caps. Plate separators prevent life-shortening internal short circuits.

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.
