Things To Consider When Purchasing A Trolling Motor Battery

Here are a few things to consider when you are looking to purchase your next battery for a trolling motor.

1. What Are My Battery Type Choices?

For a long time wet cell lead-acid batteries were the standard. These batteries use liquid electrolytes, typically in the form of water, to flood the lead plates. While all batteries tend to weigh a lot, these tend to be heavier than AGM. Understand, more maintenance is required with this type of battery. The liquid that is used to flood the lead plates needs to have the proper level. Corrosion is another issue that needs to be addressed. In comparison, AGM deep cycle batteries are completely sealed and do not require fluid maintenance in the same way a wet cell lead-acid battery does. An AGM battery typically has longer life as well, so you will go longer before needing to replace the battery.

2. What Does The Warranty Look Like?

Manufacturers with a good product are typically willing to warranty their batteries. It means they believe in the quality of their product and are willing to back the product financially if it does not meet the standards you expect. Be cautious of any battery that does not come with one. Warranties can be as short as 3 months and as long as a life-time warranty.

3. What Group Size Battery Do You Need?

Like many things in life, there is a balance between cost and quality. What is right for one person is not necessarily right for another person. When it comes to batteries you will typically find a direct correlation between the run time and the cost associated with the trolling motor battery. The longer the run time, the more expensive it is going to be. A good rule of thumb is the higher the amperage rating, the longer the run time, assuming everything else is equal.

Run time QualityBattery VoltageBattery Group SizeAmperage Hour Rating
Decent Quality12 volts2470 – 85
Better Quality12 volts2785 – 110
Best Quality12 volts3195 – 125

4. You Are Going To Need A Charger As Well

Battery chargers are used to maintain your trolling motor batteries between uses. You can use a portable one or look at getting an onboard battery charger for the greatest convenience. Make sure you get one that is compatible with your type of battery. This will help you get the best performance and maximize the life of the battery.

5. The Battery Type Affects The Weight

One of the great things about the Absorbed Glass Mat technology, besides the superior power, is the reduced weight along with better reliability.

6. Deep Cycle

A deep cycle marine battery will give you sustained power until it gets down below 80% discharge. They are designed for longer power delivery before requiring a recharge, which is perfect for trolling. Look for a flooded deep cycle that is sealed and does not require fluid maintenance.

7. Determining How Long It Will Run

Marine batteries are commonly rated using Amp Hour or Ah. It essentially tells you how long a battery will maintain a constant output. Most batteries will come with this rating, but if it doesn’t, you calculate it with the following:

Divide the RC (reserve capacity) by 2.4 to get the estimated amp hour rating. Say for example a battery has a 1600 RC, you would divide 1600 by 2.4, or 1600/2.4 = 66.6Ah

The amperage draw is how much electricity the motor will pull from the battery. The max speed and thrust of the motor determine the amount of energy drawn. a simple example is 50Ah (amps per hour / 52 amps drawn = .96 hours of run-time on your battery.

Trolling Motor Battery Maintenance

Once you have a trolling motor battery, you want to keep it in good working order. AGM Batteries require considerably less maintenance, but there are a few things you need to do. Here is a video on trolling motor battery maintenance and the things you can do to extend the life of your battery and keep it working well for hours of enjoyment on the water.
