What To Consider When Buying A New Boat Battery

Has the time come to replace the battery for your boat, but you're unsure about what kind to purchase? With there being so many different attributes of boat batteries, it can be a bit confusing to know what is the right kind. Here are a few things to consider when selecting a replacement battery.

The Battery Type

Know that there are three main types of batteries to pick from for your boat. There are starting, deep cycle, and dual purpose batteries. A starting battery is designed to output a lot of current over a short amount of time, such as when starting the engine. A deep cycle battery is going to output less energy, but sustain it over a longer amount of time. A dual purpose battery is a mixture of the two.

The type of boat you own and the accessories that you have will depend on the type of battery you need. A deep cycle battery is typically necessary for those larger boats that have running lights, a fish locator, and sonar. A starting battery is better for smaller boats that do not need the sustained output because it is just running an engine.

The Battery Seal 

You'll notice that some batteries are completely sealed and others are open and require maintenance by putting water into the battery. The difference between these two is the price, since a sealed battery costs more and does not require any maintenance. However, there are some other advantages that are worth paying a premium for a sealed battery.

A sealed battery can be positioned in any orientation necessary. You also do not have to worry about the battery tipping over, which is a possibility on a boat. It can be better for a smaller boat that is going to rock around a lot more on the water. 

The Size

Does your boat require a battery that is a very specific size, or can you pick the size of the battery that the boat uses? It's important to know the size of the battery that you can put in your boat, and if there is room to upgrade to a bigger battery. You may appreciate having the extra battery power when you are out on the water if your boat can handle it.

The Warranty

Take a look at the warranty period of the battery, which is how much time you have to take the battery in for an exchange if it is malfunctioning. You may appreciate the peace of mind that comes with a longer boat battery warranty so that you are not paying for a replacement too soon.
