What Is a Dual Purpose Marine Battery?

As the name suggests, dual-purpose marine batteries offer the abilities of both major kinds of batteries all in one unit. Rather than having a starting battery and a deep-cycle battery, dual-purpose batteries can handle both jobs at the same time. Boats with less room for larger or more numerous batteries can benefit from having a dual-purpose marine battery instead.

Depending on the battery’s construction and materials, you might find that they don’t perform as well as batteries with a more specific purpose in mind.

Note: Marine Starting Batteries

While not our main focus, it’s worth the time to mention the purpose of marine starting batteries. While they have a few other names, the major purpose for all of them is to start off your boat’s engine when you first turn it on. They don’t offer much in terms of long-term power, but they do provide a burst of energy that you’ll need to jumpstart your boat back awake after it’s been off for some time.
