Buying Guide for Best Trolling Motor Battery

While you’re doing your online research, consider the following specific factors to buy the best one that suits your needs.


Battery Type

There are three basic types of trolling motor battery to choose from:

1. Wet-Cell

These are basic deep cell marine batteries comparatively affordable, and durable enough to deal with repeated series of power drains and recharges. They need maintenance and you’ll need to replace them within a year or two.

2. AGM

You don’t need to add distilled water to it, and it also lasts longer than wet-cell batteries. It can serve you for 3 to 4 years. It is typically twice as costly as the wet-cell batteries.

3. Lithium-ion

These expensive batteries are considered the cream of the crop because of their durability. If you can maintain them at a temperature of under 105 degrees, they can last for a decade. At slow speeds, a 35Ah battery can last about 7 hours while a 100Ah battery can go for 20 hours. You can set a series of 12V batteries for more power, but the general rule applies: the higher the Ah, the longer the battery lasts for at a single charge.



AGM batteries last twice as long as the wet-cell batteries, and the lithium-ion lasts for a decade. Consider the warranty as well. Because longer warranty indicates a longer lifespan.


Vibration Resistance and Durability

Fishing boats may travel over choppy waters which creates jarring vibrations. So choose a battery capable of withstanding these vibrations than others. There are other features like spill-proof and shock-resistance that boost durability.



Consider the size of the battery and see if it fits your boat. If you have a small boat, It’s better to limit the weight to less than 40 pounds.


Convenience and Ease of Use

Consider the convenience of installing the battery you are going to buy. Some batteries are mountable at any position while others are not. Also, check whether it is maintenance-free or needs maintenance.



Choose a battery that you can use for both starting the motor and powering onboard devices. A versatile battery can be used for RVs, motorcycles, scooters, jet skis, and perhaps even for alarms and wheelchairs.


Final Thoughts

People often overlook the necessity of having the best marine battery for trolling motor, and some people have the wrong impression that the batteries available on the market are all the same. They can’t realize how wrong they are until they get stuck in the middle of the water. So be wise when choosing one for you.

 To sum up, Choose a battery that works in both saltwater and freshwater. In addition, go for the one with a great thrust power, strong shaft, tons of speed settings and runs silently. However, buy a trolling motor that suits your unique needs.
