The Marine Master batteries are renown for their proven dependability and solid performance. This flooded battery line offers a complete array of starting, dual purpose, and deep cycle solutions for virtually any marine need. Even under challenging marine conditions like wave pounding vibration, stubborn engine starting, heavy house power, auxiliary, and trolling, Marine Master batteries rise to the top in user-friendly, marine-tough service, and extended reliability.

The Dual purpose cycling/Starting battery was designed specially for the user that requires reliable starting and moderate deep cycle service. This series has all of the quality you have come to expect. Use it for your larger, harder-starting engines and/or moderate-duty trolling or accessory loads. The dual purpose is an ideal compromise between the unique demands of starting service and deep cycling, low amp draw service.
