Deep Cycle BCI Group 31M Marine and Boat Batteries
12 Volt BCI Group 31M deep cycle batteries are specifically engineered for heavy charge/discharge cycling; perfect as a house battery or running a trolling motor, depth finder, live well pump, bilge pump, or fish locator.
Should I use a Sealed or Flooded battery? Sealed batteries have high energy density, low internal resistance, and are maintenance free, spill proof. Flooded batteries are reliable, power sources with outstanding cost to power ratio. Some flooded batteries can be “watered”, if needed. Your application and maintenance plan will help in proper battery selection.
