Types of Marine Batteries

Marine Starting Batteries

Marine starting batteries (or cranking batteries) are just like the battery you have in your car. Their purpose is to give a burst of power to your engine when you start your boat. Once the engine starts, the alternator takes over to provide power and recharge the battery.

Starting batteries are perfect for getting your boat going. Still, they cannot handle continuous or frequent discharge/recharge cycles. Therefore, it should not be used for trolling motors or powering accessories. Draining a starting marine battery can shorten its lifespan.

Whether sailing the ocean or ripping it up in a motorboat, Interstate has a wide selection of powerful marine starting batteries built to withstand the most rugged marine conditions. Our marine starting batteries come with a 12-month free replacement warranty.

Marine Deep-Cycle Batteries

Marine deep-cycle batteries are perfect for powering your trolling motor and other accessories for extended periods. Unlike starting batteries, deep-cycle batteries are built with thick plates that allow the battery to discharge power continuously. Deep-cycle batteries can be drained and recharged many times over.

Our marine deep-cycle batteries are the most popular line of marine batteries and offer robust and reliable power. Designed to provide reliable power over an extended period, our deep cycle batteries are ideal for powering your boat and all of its accessories, whether your engine is running or not. Our new marine enhanced flooded batteries (EFBs) come with a 24-month free replacement warranty.

Marine Dual-Purpose Batteries

A dual-purpose marine battery offers you all the cranking power of a traditional starting battery plus the continuous discharge of a deep-cycle battery. It is ideal for smaller vessels that lack room for two separate batteries.

Initially developed for military tanks and submarines, our marine absorbed glass-mat (AGM) battery with Pure Matrix® power packs the staying power of our best deep-cycle battery with the high-cranking performance your boat needs. With pure, non-alloy lead and the most efficient plate design in the industry, this battery puts the most advanced technology on your side. With faster recharging and two times the overall life of a flooded deep cycle battery, the Pure Matrix AGM stays ready for all your fishing weekends.
