Baterías marinas

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. Nuestras baterías de arranque marinas vienen con una garantía de reemplazo gratuito de 12 meses.

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.
