What You Need to Know About Marine Dual Purpose Batteries

Marine dual purpose batteries are versatile power sources designed to serve both starting and deep-cycle applications in boats. They provide the necessary power to start the engine while also being capable of running onboard electronics and accessories, making them ideal for smaller vessels where space is limited.

What are marine dual purpose batteries?

Marine dual purpose batteries, also known as hybrid batteries, combine the features of starting and deep-cycle batteries. They are engineered to deliver a high burst of power for starting the engine, similar to cranking batteries, while also being able to provide sustained energy over longer periods for powering electronics and accessories.

How do marine dual purpose batteries work?

These batteries utilize advanced technology that allows them to handle both high current demands for short durations (starting) and lower current demands over extended periods (deep cycling). This is achieved through a design that incorporates thicker plates than standard starting batteries, allowing for deeper discharges without damaging the battery.How Marine Dual Purpose Batteries Work Chart

What are the benefits of using marine dual purpose batteries?

Marine dual purpose batteries offer several advantages:

• Versatility: They can start engines and power accessories, making them ideal for smaller boats.
