Why a Marine battery?

A starter battery is designed to provide a large amount of power in a short space of time to enable starting the engine, and then being quickly recharged. A marine battery on the other hand is designed to store power and release it over a much longer period of time.

Undoubtedly you can use a starter battery for some marine applications but it is unlikely to work very well in the wrong application & will almost certainly fail prematurely.

The Shield Marine range included are high quality starter, dual purpose & deep cycle batteries designed for use on the water. A varied choice of ampere hour ratings of sealed & non-sealed batteries all with convenient carrying handles provides great value for money and impressive performance capability making them ideal for a multitude of marine applications.
