About trolling motor battery

Best Trolling Motor Battery Blog Pin

A trolling motor battery is one that has been designed with the intent of providing electricity to the motor over an extending period.

It sustains the amount of power needed for fishing trips and is essential to avoid battery failure.

In a trolling motor, marine batteries are required, which act as a vital unit to start the engine and provide power to start the motor connected to the boat.

Usually, for a trolling motor, a battery is required. There are several varieties of marine batteries, such as starting batteries, deep cycle batteries, and dual-purpose batteries. Out of the three, the deep cycle battery is majorly used.

Trolling motor batteries have various properties and are of different types.

Types of trolling motor battery

A green battery

Wet cell

These batteries refer to the cells in the battery immersed in a solution of sulphuric acid and water. This battery requires maintenance as per frequent usage and overcharging. It is recommended to check the battery before using, to make sure adequate water is in the battery. You can add purified water if the water level is down to prevent the battery from being damaged.

The wet cell batteries are affordable, and if they are adequately maintained, they last for a long time.

The wet cell batteries also have a high number of charge-discharge cycles, which means they are also less likely to suffer overcharging damage.


The Absorbed Glass Mat (AGM) is also known as Lead-acid wet cell batteries, a common type of battery to use with trolling motors. These batteries are sealed completely, and it is fit for everyday uses of a trolling motor. They need some maintenance and last around 2-3 years.

These types of batteries are spill-proof as they have glass mats that prevent any spillage or leakage. AGM’s also have a high-power output and a short charging time. That doesn’t mean the life span doesn’t last long; they are quite a durable option as they are unlikely to build up any kind of sulfation.

Gel cell

The battery is similar to the AGM battery in terms of the mixture but different on a technical note. Gel batteries last longer in hot weather applications and offer remarkable resistance to any kind of leakage and enhance stability with few maintenances.

These batteries are easily installed and have a long standby life with a good performance rate.


Lithium-ion batteries, also known as Li-ion batteries, are among the most popular forms of rechargeable batteries. They are considered to be pretty stable and maintain their charge for a longer time.

Other than that, it offers a great energy-to-weight ratio, low self-discharge rate, high open-circuit voltage, no memory effect, etc.

They can be recharged hundreds of times and tend to have a higher energy density.

Dual-purpose or deep cycle battery: Which is better?

battery and wires

Dual-purpose batteries deliver powerful cranking amperage for smooth and easy starting of the motor and have a low amp draw service.

They are ideal for applications that require starting. In comparison, a deep cycle battery is one that provides continuous power over long periods. These batteries can be drained and recharged many times.

Ideally, you need a battery for starting, and a deep cycle battery is required for the trolling motor. However, if there is less space onboard, you can choose one battery depending on the power draw required.

A deep cycle battery is built to withstand many discharges and recharges, while the dual-purpose battery is not. Dual-purpose batteries cannot withstand well to total discharges and recharges.

A dual-purpose battery is also more prone to overheating, which is not an ideal option. It is recommended to use a starting battery and deep cycle battery. Still, the dual-purpose batteries work well for short trips and are maintained properly. Other than that, there are some deep-cycle batteries that one can use to start an engine.

How to Choose a Trolling Motor Battery – Factors to Look For

How to Choose a Trolling Motor Battery infographics

Before buying a battery, there are some factors that you have to understand properly. It must be a well-performing battery that is compatible with the motor and includes a good reserve capacity or life span.


Most batteries offer 12 Volt, but a good option for a trolling motor would be a 24-volt battery. But, then for regular use, a 12-volt battery just works fine, or you can set up two 12-volt batteries as we have mentioned in the steps above to get a 24-volt battery.


Before making a purchase, make sure you research the battery’s lifespan if it works well in the long run as the battery can be an investment.

You may select any brand that offers warranties up to 3 to 5 years and has a sturdy, good build quality, and excellent service life of 8 to 10 years.


It is important to choose a durable trolling motor battery as it is an investment, and most batteries are expensive. Make sure you check reviews well before making a selection. Look for brands that offer a good warranty, over 3 years or more.


Before choosing the perfect battery for your trolling motor, make sure that it is not too heavy. If the weight is heavy, it necessarily doesn’t have to be a good product.

A lightweight battery is usually recommended for a trolling motor, and an ideal weight should not be over 45lbs.


Ensure the size of the battery so that it’s perfectly suited for your boat. If you have tight space, then look for compact batteries. Heavier the boat, more power is drained every hour, which requires a larger battery.

It ensures that you have enough charge to power the motor for longer durations, giving you more time on the water. So look for larger ones but also see the space you got on your boat for the same.

Ampere Hour Rating

Consider the ampere-hour rating as similar to the gas tank of a car. A battery with a 125 amp hour rating will run more than a 100 amp-hour rated battery.

Here is a chart that will help you pick the right trolling motor battery according to the AMP.

Trolling Motor ThrustMax Speed CurrentMedium Speed CurrentMinimum Speed Current

We recommend using at least a 100 ampere-hour rating, group 27 rating, and 175 minutes of RC(Reserve Capacity). Here is a table for you to pick the right trolling motor battery according to the size and the voltage or Amp/ hour.

Which is the best trolling motor battery, and what are its advantages?

The ideal trolling motor batteries are the AGM (Absorbent Glass Mat) batteries. It uses almost similar elements as lead-acid batteries. Still, they are different in many ways. Rather than using acidic water, it is constituted of glass fiber matter covered in sulfuric acid. It is maintenance-free and compact, which makes it an ideal pick for a trolling motor.

Here are some of its advantages:

  • The AGM is lighter and smaller compared to other batteries.
  • It requires less or no maintenance; hence it cuts down the hassle of changing any liquids or cleaning.
  • It allows fast charging due to low internal resistance.
  • These AGM batteries are sealed and can be used, stored, or transported in any way.
  • The AGM battery is free from any hydrogen emissions.
  • These are also fit for long-term storage, and the charge remains even if the battery is kept ideal.
  • It is easily available.
