Bosch Marine

Bosch marine batteries are carefully engineered to provide the optimum balance between starting and deep cycling duties. They are also thoroughly insulated to protect against the high frequency vibrations created by rough sea conditions. Bosch batteries are specifically designed for a range of marine applications that require frequent charge and discharge cycles, in order to perform under extreme conditions. Bosch has been manufacturing batteries since 1927, so with 85 years of product development, you can be assured of high quality, reliable performance and extreme efficiency.
