Trolling Motor Batteries – Buyer’s Guide

The Deep Cycle Standard

Most marine trolling batteries are designed as deep cycle models; this means the battery can handle hundreds of charge and discharge cycles.

It is important to consider this essential feature before taking the buyers’ leap; it helps you maintain durable and stable battery life for a protracted period; all you need to do is recharge the battery; once it is drained and becomes reusable again. You will need to do this properly and ensure the battery is fully charged before the next use. There are two types of trolling motor batteries to look out for in a model.

There are two types of trolling motor batteries to look out for in a model.

Sealed AGM vs. Wet Cell Lead Acid

1. Absorbed Glass Mat (AGM)

This type of battery design features a sealed body that conserves charges in the electrolytes in glass mats and not in fluids. It uses thin glass fibers woven together to increase the surface area of the electrolytes.

AGM safeguards the battery from vibrations and shocks, ensuring no acid leakages or gas spills. An AGM battery does not require much maintenance and can last up to five years.

Lead Acid Wet-Cell

2. Lead Acid Wet-Cell

The lead-acid wet-cell requires a fluid medium (sulfuric acid & water) to keep the electrolytes in good condition. In some situations, you will need to add distilled water to keep the battery going.

These batteries also need to be kept in well-insulated areas as there are very vulnerable to vibrations. Batteries designed using lead-acid wet cell has an average lifespan of about two years.   

Factors To Consider When Choosing Best Battery For A Trolling Motor

Voltage

The voltage of the battery should be the first feature to consider. Most standard batteries make use of 12 volts for their operations.

Weight

Don’t you think it will be frustrating to purchase a model that will end up bogging down your boat? So, the model you’re going for should feature a lightweight design to ensure easy mobility and avoid bogging down your boat.

What is a good battery reserve capacity?

The reserve capacity explains the time frame for a battery to retain or discharge  25 amps until it gets to 10.5 volts. A battery with an extended reserve capacity will serve more when used.

Cold Cranking Amps

CCA means the ability of your battery to start even in icy regions. This is a feature you must consider, especially if you live in a cold environment, as it plays a role in determining the battery’s performance.

It would help if you had a battery that can produce at least 7.2 volts at 0 degrees Fahrenheit for a standard CCA output.

Amp-Hour (AH)

The amperage hour rating of a boat is similar to that in a car. The AH determines how long a battery can run during use. So, a battery that features more amp-hours will work longer than the one using less. 

The amp-hour works hand-in-hand with the power of your boat consumes. If you’re looking for a battery that runs for hours, look out for the models AH.

Points For Maintenance

  • Always Charge the battery once it drained out.
  • Ensure it is fully charged before storage.
  • Clean corroded part using baking soda.

It’s recommended to use a trickle charger with the battery. The charger will prevent the battery from draining excessively when not in use.
