Tough battery works in tough conditions


Excellent battery that has served us very well in a pretty demanding marine environment. We constantly start and stop, then restart, our engines, and this battery has never let us down.

You get a workout carrying this beastie, but it is worth it for the superior construction.


Power for your RVs, trolling motors, marine accessories, and starting needs in all weather. 205 Minutes of reserve capacity - Ideal for multiple electronic accessories and in the ice fishing house. Deep discharge recovery, perfect for marine & deep cycle applications. Combination stud/post terminal design lets you use any normal connectors.

Absorbed Glass Mat construction makes this thing weigh a lot but allows a non-spillable design for mounting flexibility & gives it longer maintenance-free life and better vibration resistance.
