Marine Batteries – What To Look Out For

There are three different types of batteries you can find on your pontoon or small boat. The first type is of cranking type which is connected to the starting mechanism of your power motor. They are also called as the primary marine batteries as without them you cannot start your boat motor.

The second type are the ones which used to power accessories on board like fish finder, lights and other power requirements. Unlike cranking batteries which can hold sudden high amp load; these are best suited for constant long for prolonged use. The only other type that you may find are the dual purpose batteries; the one which serves the purpose of both.

Cranking batteries while need a constant charge or float charge to be specific the deep cycle batteries can be discharged and recharged again without negative effects. It’s much like the one used in our cellphones and laptops which we can charge and discharge based on ease and availability of power.

Many boats including kayak and pontoon also have more than one such batteries for the single purpose. For example a boat with 24 volt trolling motor may have two 12 volts cranking battery connected in series. There is a good chance that you replace only one of them with the new one; only to latter find it get drained and fail way before expected.

This happens when you connect a old battery with a new one. The old battery then drag the new one to its limit to maintain equal amp rating; thus causing it to fail early. So it’s always wise to change complete set at a time rather than getting into a continues loop of replacing one battery at a time.
