Pros

  • Lightweight (24 lbs.)
  • Long warranty means the manufacturer is willing to stand by their product

 

Cons

  • High price point

Universal Power Group 12-Volt 100-Ah Battery

For those of you who are gluttons for power and find the 35-Ah too underpowered to meet your trolling motor battery needs, the 100-Ah model from Universal Power Group just might fit the bill.

What We Don’t Like

We don’t like the weight and the price, but considering that this battery is supposed to deliver three times the power of a 35-Ah battery, these make sense. The size is also going to be a problem on smaller boats.

 

Pros

  • Large power reserve
  • AGM technology to ensure safe leak-proof use

 

Cons

  • More than double the weight of a 35-ah battery
  • Rather bulky

  • Meant to last for five years

 

Cons

  • Abnormal battery size

Trolling Motor Battery Buying Guide

Now that we’ve reviewed our top picks for the best trolling motor battery, let’s explore the considerations we used to compile these reviews. We invite you to consider these things as well when you are selecting a trolling battery for your use.

When it comes to trolling batteries, people pay attention to the crucial details. Due to brand familiarity, people do not necessarily pay attention to specifications and compatibility with their trolling motors. We don’t recommend a general approach to a specific trolling motor. The trolling motor battery should match the engine if you don’t want to have problems later on.

Having only a single option due to brand quality and assumptions about how a trolling battery will “work” is insufficient. You should also take into consideration the configuration when choosing a trolling battery for your motor. Specifically, the types of batteries (cranking and deep-cell batteries) and whether a trolling battery should be dual purpose, wet cell, or gel boat should also be taken into account.

 

 

Best Trolling Battery Tips

A couple of things must be considered to find the best trolling motor battery. To save time often wasted due to trolling battery issues, you must consider the battery type and the amperage of the battery before buying.

Take note of the following, and you will do yourself a huge favor.

 

The Type of Battery

Two types of 12-volt batteries are currently industry staples. These are the Wet Cell Lead-Acid Batteries and Absorbed Glass Mat or AGM. Whenever you look at the commonly available battery types, they will most likely fall into one of these two classes.

 

See the pros and cons of each type of battery below.

Wet Cell Batteries*** Absorbed Glass Mat or AGM
Pros:

· Usually cheaper than AGM

Cons:

· You have to top off wet cell batteries once in a while for them to work

· Sensitivity to vibrations

· Have to be installed upright all the time for the wet cell batteries not to spill

· Not as safe as AGM batteries

Pros:

· More modern battery option

· The batteries are sealed and, therefore, not prone to spilling like wet cell batteries

· The battery lasts longer

· More versatile and not prone to vibrations

· Safer than wet cell batteries

Cons:

· Usually more expensive than wet cell batteries

***Lithium-Ion Batteries are not included in the classification because you will have to shell out a considerable sum of money to get one. We do not recommend that you get a Lithium-Ion Battery due to this high expense.

 

Amperage Hour Ratings

Looking at a battery’s amperage and knowing the amps of your motor will let you determine the longevity of the trolling battery in your trolling motor. The higher the amperage, the longer your battery is expected to last under typical working conditions.

Of course, you also need to consider that your trolling motor may use more electricity than the average, so you’ll need to know the electrical consumption of your motor before you decide on which trolling motor battery to buy.

Another related consideration is how much use your trolling motor will have during a typical trip. For example, if you are a master angler who uses your trolling motor for precise movement, you probably should lower your expectations for total battery life, but if you have modest demands, the battery can last for a long time.

 

Here is the equation for this with a couple of examples:

 

Operating Hours of the Battery =

 

Example 1: =

 

Example 1: = 11 hours on low speed

 

Example 2: =

 

Example 2: = 1.83 hours on low speed

 

These two battery features will quickly determine if a specific trolling battery is right for your trolling motor. As our example demonstrated, the amount of power drain is what tends to determine how long your battery lasts.

In example one, the trolling motor has modest power demands so that it can last for 11 hours on low speed. By comparison, the second example shows that a motor that consumes a lot of power will quickly drain your battery.

Please note that these are low-speed settings. The rate at which trolling motors drain battery power is not necessarily linear. The first battery might use only 5 amperes per hour on a low setting but consume 50 on its max setting. You will have to read up on the capabilities of your motor to be sure that your battery will meet your needs.

 

Cost

Once you have narrowed down your list of trolling motor batteries to the ones that are compatible with your machine, the next thing you should consider is cost. There is a correlation between quality plus battery life and price.

Getting the cheapest model will likely yield a battery that will quickly lose charge and leave you hanging just as you need it the most. The most expensive battery will last for a long time, but it might not be worth it if it also breaks the bank.

Go for a modestly priced model that gets you what you need. Remember, you won’t need to keep your trolling motor running all the time. It wouldn’t surprise us if you learned that your trolling motor is only running for an hour at most during a whole day of fishing. Also, remember that you can recharge batteries, so there is no need to buy a battery that can last for tens of hours unless you plan to take trips that require that sort of usage time.

 

 

Weight/Size

Another consideration is the size and weight of the battery. Your fishing boat or kayak will have limited cargo space. Note what we said about the fact that your trolling motor doesn’t need to run all the time. The size and weight of your battery must compete with all the other equipment and whatever fish you catch.

The battery capacity tends to be proportional to the weight and also the size of the battery. The larger your battery and the heavier it is, the more charge it can hold. So, depending on your needs, you will want to keep your trolling motor battery modest. It’s just a backup motor battery after all.

On the other hand, the trolling motor can be a kind of backup power, which you can use if the primary motor fails or if you lose your oars. So, don’t think you can get away with an overly modest battery. You might need your trolling motor to bring you back to shore or to get help when an emergency happens.

 

Warranty

Finally, consider the warranty of the brand you want to pick. A good brand will always stand by its products. So, you want to get a battery from a good brand to make sure that you won’t be stuck with a lemon.

Fortunately, most brands are willing to guarantee their products, so the choice will likely come down to whether the brand is capable of attending to your battery if it fails. For instance, if you can return the battery to the store where you bought it to have it serviced, that is the sign of a great brand.

 

Final Thoughts

We’ve laid out several good choices for you, including their strengths and weaknesses and other interesting facts about them that might help you decide whether to buy or not. One of our picks for trolling motor batteries would surely work for whatever motor you have, whether transom or bow mounted.

If you wish to make the best of your fishing experience and use your trolling motor to make precision maneuvers to get at the fish you desire, I hope you read through our trolling motor battery reviews and found a battery that works best for you.
