marine batteries

Because of the exposure to harsh conditions on the water, boats require specialized materials to minimize the wear and tear that can happen over time. One important factor to consider is choosing the right marine battery to keep your boat running.

3 Types of Marine Batteries

There are three basic types of marine batteries available. Here’s an overview of your options to help you choose the ideal product for your boat:

Starter Battery

The name of this battery describes the function – it helps the boat motor to start. Another common name for the starter battery is a “cranking battery.” These batteries push out a large amount of power in a small window of time to get the motor running, but it doesn’t sustain the power to keep it running.

Deep Cycle Battery

Once the starter battery brings the motor to life, then the deep cycle battery takes over to provide consistent, steady power. A deep cycle battery can be charged and discharged for multiple cycles to keep the motor going and power your boat and fishing tools, including GPS, lights, fish finder, and more.

Dual Purpose Battery

Since you need both a starter battery and a deep cycle battery to keep the motor running, it makes sense to invest in a battery that can handle both of these jobs. A dual-purpose battery combines both benefits. But the design has a potential drawback because their lifespan and durability are lower than other types of batteries. For example, the available cycles in a dual-purpose battery are much lower than what you can get from a deep-cycle battery.

Other Battery Features to Consider

In addition to the different types of batteries, there are other options for the chemistry and function of the battery. Some materials are better than others in performance and durability.

Examples include lead-acid marine batteries or ionic lithium batteries. Lead acid batteries tend to be cheaper to buy, but they don’t last as long as the durability that you can get from a lithium battery. Lithium batteries tend to be best used for trolling motors, sailboats, and houseboats. 

Also, consider the size and power of the battery to ensure that you have a strong enough battery for the size of your boat. If you have questions about choosing the right battery, then it makes sense to talk to an industry expert for personalized recommendations.
