The marine battery you choose is a critical part of your trolling motor system. Experienced anglers will tell you that a deep cycle marine battery is best since you can use it to the point of depletion and recharge it without ruining the battery.

The idea is to get a good-sized battery that offers at least 12 volts’ deep cycle and is rated at around 110 amp-hours. However, if you like going way out into the water, you might be better served by a marine battery that offers higher amp-hour ratings.

How to Choose the Best Marine Battery for Trolling Motor

As an avid angler, you most likely want to have the best apparatus for your hobby. It has been said that fishing isn’t exactly the cheapest of hobbies, but if you make the right kind of investment at the start, it gets fairly affordable down the line.

The trick is finding the best products and investing your money in them, knowing that they will serve you well for years to come.

That being said, there are hundreds, if not thousands of marine batteries for trolling motor options in the market today. And as you would expect, they are not all created equal. As such, you need to be very careful how you pick and choose among the available options. Here are some factors you might want to consider if you invest in the best marine battery for your trolling motor.

Recharging and Reserve Capacity

The trolling battery reserve capacity is one of the most critical elements you need to consider. Marine batteries, like most deep cycle batteries, can be used to the point of depletion. The catch here is that they need to be charged almost immediately they hit that point of depletion, or you risk ruining the battery and needing a new one.

The battery’s reserve capacity rating gives you an idea of how long you can use the battery (no fast discharges) before you need to recharge it. It also shows you just how far into the lake you can go and how many days you can keep running that battery without charging it.

This factor is particularly crucial for people who love taking long fishing trips that last for days. One of the best ways to keep yourself protected is to get a marine battery that can be recharged via solar. This means you won’t have to turn back and head for land and a charging port every time you come close to depleting it.

Battery Size

This is kind of a problem when it comes to marine batteries. In essence, larger batteries often mean that they can last longer and serve you better. However, larger batteries also take up too much space on deck, which can be a bit of an issue if space is limited or you would rather use that space for other gear.

You have to decide which is more important to you: a larger battery that lasts long or the space. That being said, the battery’s amp hour rating is also quite important as it will help you determine which kind of battery is ideal for your specific boat.

Voltage

Most of the marine battery options you are going to come across are 12-volt batteries. That’s because most boats use a 12-volt battery that can power the onboard electronics and help keep the boat operational.

However, in some cases, you may find that your motor has a 24-volt rating, which means you need to get two 12 volt batteries to operate. Granted, this is quite rare, but if that’s the case, you need to keep an eye out for the battery voltage and maybe double up on your batteries if you have a 24-volt motor to run.

Durability and Maintenance

When fishing, you are going to run into some wild and choppy waters from time to time. You need a marine battery that is built for tough. One that can withstand that kind of abuse and that is durable.

You also need to buy one that is maintenance-free and allows you to enjoy your fishing without worrying about acid top-ups and such. Finally, these kinds of marine batteries can be mounted in any orientation, making them quite ideal as a trolling motor battery.

Angling should be a fun hobby. To achieve this, you need to buy the best components and apparatus. The best marine battery for your trolling motor is just a start.
