Marine Batteries

Powering adventures at sea


From the No Wake Zone to the Open Ocean

Boats require a lot of power. Most boats have two batteries to operate smoothly:

  • Starting Battery
  • Deep Cycle Battery 

Starting batteries supply the burst of energy needed to start the engines while deep cycle batteries supply constant power to run all other onboard electronics and boating operations. Both batteries have to withstand harsh conditions and rugged use in the water, so a good marine battery is built to last in these conditions.
