Best Deep Cycle Battery Trolling Motor – Top 8 Reviews In 2023

Best Deep Cycle Battery Trolling Motor

A trolling motor is a small power source for a boat’s propeller. The power can move the boat forward or backward, stop it, and turn it. The size of the trolling motor depends on its purpose and uses.

For example, it could be as large as 100 horsepower (for boats such as Maine’s 1-1/2-ton lobster boats). That means that the trolling motor’s battery powering should also be big enough to support this kind of low voltage usage.

A trolling motor works best with deep cycle batteries. A deep cycle battery can be used over and over again.

With a regular old car battery, you would not be able to use it for much other than starting your car when it’s dead. You could also use an old car battery in a boat because you only need to start the boat up once.

There are many types of deep cycle batteries. The most common are sealed batteries, Flooded Batteries, and gel cell batteries.

Sealed – There are at least four types of sealed batteries. They are lead-acid or flooded, absorbed glass mat, AGM or Gel Cell, and sealed lead-acid.

These all have advantages and disadvantages over each other. So we can agree on the fact that it is quite hard to find the best fit. To help you get the best, we are up with the list of the best deep cycle battery trolling motors.

Consideration Before Buying The Best Deep Cycle Battery Trolling Motor

Buying the best deep cycle battery for your boat or inflatable is something that can be a little confusing.

Before buying the best deep cycle battery for your trolling motor, here are some things to consider that will help you choose the right one.

Let’s get into three main considerations Before Buying the best Deep Cycle Battery For Trolling Motor.

1. Size Of Your Boat

The size of your boat is one of the most important things to consider when buying a deep cycle battery for your boat.

If you have a bigger boat and want to use your trolling motor, it may be time to choose a bigger deep cycle battery for a larger capacity deep cycles battery.

You can get an extra-large deep cycle battery that provides more power and would last longer. Still, you will have to add yet another accessory: a charger, bank box, etc.

2. State Of The Technology

There are two different types of deep cycle batteries available in the market. They are flooded and gel. While both these types remain popular in the industry, there are certain differences between them.

Gel deep cycle batteries provide more power for your trolling motor, but they have limitations when it comes to how long it will last.

Usually, gelled deep cycle batteries can last around 10 years, while flooded ones usually last about 3 to 5 years. 3.

3. Maintenance

Like almost all other batteries, deep cycle batteries also have a shelf life, and therefore you have to take care of them if you want them to last long.

The first and most important thing that you need to do is charge your trolling motor after every day of use. If not, charging your trolling motor every day will reduce the life of your battery.

You should also avoid overcharging as it may reduce the number of charges your battery can provide before it dies out completely.


 The best deep cycle battery for trolling motors can provide an adequate and steady voltage throughout deplete. Deep cycle batteries should hold their charge and not dissipate power when they’re in standby mode.

Whatever you do, please don’t skimp on your battery’s amp-hour rating; it’ll be well worth the investment once you get a boatload of gear powered up. So choose wisely to be worth your time and money.
