Buyer’s Guide

With so many products on the market, there is an ocean of information that comes along with such variety. We have categorized the most crucial aspects of batteries for trolling motors and batteries in general. Read ahead to better understand the factors that will decide your next buy.

Battery Types

Although there is a vast variety of various types of batteries for trolling motors, but the two most important and crucial ones have absorbed glass mat batteries commonly referred to as AGM batteries, and lead-acid wet cell batteries.

AGM batteries are not inexpensive but that is because they are maintenance-free and require no upkeep in the lifetime of their usage. On the other hand, lead-acid wet cell batteries are cheaper but of course, require to be looked after such as the periodic pouring of water.

Amp Hours (Ah)

Ampere hours or Amp-hours for short is basically the most crucial factor to consider when buying a motor since it will define the time period for which your battery will be able to provide power.

Amp-hours is basically a measure of the charge inside your battery that allows, for one hour, the discharge of a single amp. The higher the amp hours the more charge or electricity it can store. But all batteries are different, and some require different amp hours to function.

There is no fixed standard however generally, a 25 – 50 Ah is enough for a small battery.

Power System

The power system basically refers to the voltage your trolling motor requires. Most trolling motors function at 12V however, some can require 24V. For that several batteries will have to be combined.

Deep Cycle

Deep batteries are lead batteries that are different from other styles of batteries since they provide sustained power and can run until they are eighty percent discharged. The flooded deep cycle batteries are the most common ones, they are maintenance-free and sealed.

Design, Construction, and Maintenance

When it comes to design and maintenance there is a direct relationship between the two. The way a battery is designed dictates if it requires maintenance or not.

The AGM batteries are maintenance-free due to their modern design whereas dual-purpose, deep cycle batteries have a thick plastic coating to provide a vibration-free experience.

Weight

Another important factor to consider is the weight of the battery. It’s a given that the size of a battery is directly proportional to its performance meaning the large a battery is, the more power it has.

Having said that you can’t just for the largest product on the market hoping it will be the best one. Since there are factors to consider and especially the fact that most boats, canoes, or kayaks don’t have enough space and thus require smaller motors and in turn smaller batteries.

Charging Time

Charging time is a personal preference. Basically, if you are an avid user of your boat and visit the lake regularly you will need a battery with a low charging time whereas if you don’t visit that often and your battery utilization is minimum then you don’t have to worry about the charging time.

FAQs

1. How often should I charge the trolling motor battery?

The trolling motor battery should be charged immediately after each use. this ensures that the battery never runs out of charge and is always available for use. Be careful of overcharging.

2. How long will a trolling motor battery last?

The lifetime of a trolling motor battery depends upon the type of battery it is for example AGM batteries have a life expectancy of somewhere between two years to four years whereas lithium ion-based batteries average around 10 years.

Another factor that can influence the lifetime of a battery is its usage – how often it is used and how it is taken care of.

3. Are AGM batteries better than wet cell batteries?

In terms of quality AGM batteries are better than wet cell batteries since they’re maintenance-free and have a good life span. They also charge quickly and don’t require much care. However, they are costlier as compared to wet cell batteries so it is a tradeoff between quality and price point.

4. Do I need a deep cycle battery?

Trolling motors function perfectly well when they are used with deep cycle batteries since the Motors are operated for several hours and a continuous charge is required. So, the more charge the battery offers the better the Motor will function.

Some deep cycle batteries are dual-purpose and can act as starters as well as deep cycle batteries however, they are not as efficient as dedicated deep-cycle only batteries.

5. Do I need to clean the trolling motor battery?

Not necessarily, if it’s an AGM based battery it won’t require any maintenance except for the fact that you might need to wipe off some mud here and there, after using it and even other trolling motor batteries don’t require much cleanup.

6. How should I store the trolling motor battery?

Most batteries are permanently installed into the boat so there’s no need to worry about its storage. However, if you don’t plan on doing so and need to store it somewhere then we recommend a cool and dark place such as a garage or a basement so, that it is below the room temperature.
