Which Marine Batteries Do You Need?

Starting marine batteries deliver large bursts of power, like a car battery, making them ideal for starting boat engines.

Deep-cycle marine batteries deliver a steady current, capable of powering a trolling motor or electronics, for hours and hours. They can be absorbed glass-mat batteries or specially formulated lead-acid batteries.

Dual-purpose marine batteries can do what both starting and deep-cycle batteries can do: start engines and run hours of power.

Watercraft marine batteries deliver starts and running power in a compact, powersports design for sporty personal watercraft.
