Boat & Marine Batteries

Deep-cycle and starting batteries built for life on the water. We stock marine batteries for everything from small fishing boats to larger recreational vessels.

Overview

Power for Every Trip on the Water

Whether you're heading out on Lake Erie, Lake St. Clair, or the Detroit River, a reliable marine battery is essential. At The Battery Man Windsor, we carry both starting batteries and deep-cycle batteries to cover all your on-water power needs.

Marine starting batteries deliver the burst of power needed to fire up your engine, while deep-cycle batteries are designed to provide steady power over longer periods for trolling motors, fish finders, and onboard electronics.

We'll help you choose the right battery type, group size, and reserve capacity for your specific boat and how you use it.

Helpful Tips

Battery Care & Maintenance

  • 1Always use a marine-rated battery — automotive batteries are not designed to handle the vibration and moisture of a boat environment.
  • 2Deep-cycle batteries should not be discharged below 50% regularly — doing so significantly shortens their lifespan.
  • 3Store your marine battery fully charged over the winter and use a maintenance charger to keep it topped up.
  • 4Check battery terminals and connections before each season — corrosion is common in marine environments.
  • 5If you run multiple accessories (trolling motor, fish finder, lights), consider a dedicated deep-cycle battery separate from your starting battery.
