Things to Look for in a Trolling Motor Battery (Your Trolling Motor Battery Guide):
If you are new in buying a trolling battery, it may seem like most of them are the same. However, there are some factors that you need to consider when looking for a trolling motor battery. The best ones are always durable, light and reliable. And the quality may dramatically range from its capacity. Here are three features that we’ve listed you should look for in a trolling motor battery:
Deep cycle batteries come with a rating of amp hours. This is a unit that measures the total amount of charge inside a battery, which enables a single amp of current to discharge over a time of one hour.
Simply put, it’s the number of amp hours that determine how much electricity the battery can store.
This is seriously one of the most important metrics that you should look in a deep cycle battery as this is what ensures how long the battery can power a trolling motor.
It’s not available for dual-purpose batteries, which makes it difficult to calculate the total amount of time that the battery can power.
However, just so you know, small batteries usually measure 25 – 40 Ah, while larger deep cycle batteries can reach up to 100 Ah.
In reality, there are no perfect amount of amp-hours in a trolling motor battery. The higher the ampere-hours will be, it would mean that the battery can power your trolling motor for longer.
Nearly all deep cycle batteries are manufactured in 12-volts. This means that you will need a few batteries to power a 24-volt trolling motor. Before you go on buying a battery, you need to be aware of your motor’s power system and its demands.
The reason why it’s important to look at the weight of a trolling motor battery is that you need to check if it’s going to fit in your vehicle or watercraft’s weight limit.
Moreover, the heavier it will be, the more troublesome it would be for you to set it up. Most batteries these days weigh somewhere between 20 – 50 pounds.
The lower the weight of your battery, the better it is for you to maneuver around. Then again, it depends on your capacity too. Most kayakers or anglers prefer to have a battery below 30 pounds.
Design, Maintenance, and Construction
Modern AGM batteries don’t require much maintenance, which makes them a convenient choice for professionals.
They are way easier to own than those traditional, heavy-maintenance batteries. They even make a safer option to use, whether you are looking to mount it side up or upside down.
Some of them are also constructed with an extra thick plastic casing that insulates and protects the battery from extreme vibrations.
This, along with AGM technology make great features to extend a battery’s lifespan to save you from having to replace your battery annually.
Cold Cranking Amps
Cold-cranking amps (CCA) is the number of amps that your battery will release during the first 30 seconds of starting up at 0-degree Fahrenheit.
This is mainly important for stating power batteries that need a massive amount of energy for a short period of time.
You won’t need to look for CCA into a trolling motor batter unless your battery has two main functions; starting your electrical equipment and keep it running for hours.
Why You Need a Trolling Motor Battery?
Here are five reasons that contribute to the positives of owning a trolling motor battery:
- Environmentally friendly: Whether you know it or not, but trolling motor batteries are very much environmentally friendly. They run seamlessly, and that’s why they are very quiet to the environment around them. They do not create any interference with other boaters, flora or fauna. You would be very fortunate to own one of these batteries.
- Easy to Maneuver: Trolling motor batteries are very lightweight and easy to install. Within a very small space, you can mount it in your boat, kayak or other off-road vehicles. This motor battery gives you better maneuverability. They are available in a number of pressure levels, and it meets all the environmental situation that may arise.
- Great for you to steer the boat that helps you to control it very efficiently.
Frequently Asked Questions (FAQs)
Q1: Which is the appropriate size of the solar panel that I need for my trolling motor battery?
Answer: We wouldn’t suggest solar for recharging in a trolling application, only battery maintenance. The amps included are rather substantial.
For support, one 2.5-watts solar maintainer per profound cycle battery works or for a 24-volt system, a 10-watt unbreakable solar panel also works.
Large solar arrays on the roof of boathouses work as well, but it’s more complex, and the cost is even more significant.
Q2: Where do I store my batteries?
Answer: You really need to be aware of your batteries. Don’t mix the different types and separate the old ones from the new ones.
Always keep the batteries that are not in use in a dark, and slightly below room temperature condition.
The place should be cold and dry, but don’t overdo the coldness because it will just end up destroying the batteries.
Q3: Is trolling motor batteries bad?
Answer: The best way to tell if your battery cells have spoilt or not is to check the specific gravity. This specifically works for wet lead batteries.
Basically, the specific gravity helps in determining the concentration of the acid in the water. So, if one cell has +/- 30 kg/m3 of the other cell, then the battery is of no use.
For other types, you can only pull out the multimeter. It’s going to show you all that you need to know. Replace the batteries as soon as you can in order to avoid further damaging your trolling motor.
Q4: What does it mean when they say that trolling motor batteries are maintenance-free? Shouldn’t I clean it?
Answer: Clean? Not really. But maintain? Before we proceed, let us tell you that clean and maintain are two different things when it comes to trolling motor batteries.
Yes, you do need to maintain your trolling motor battery. We have observed that many great batteries simply spoil because of a lack of care.
You can clean your battery if you see that it has started showing signs of eroding. Keep dirt and other grime off your battery.
Wet lead acid batteries should be refilled with distilled water whenever required, and must be kept under supervision. Use tools such as hydrometer to test the concentration of acidic substances.
You also need to take care of whether the battery acid is overflowing or not. These batteries do require a lot of labor in terms of maintenance.
Though we have mostly reviewed out AGM batteries as completely maintenance-free, there are some necessary steps that you have to take to protect your batteries. Watch its charge.
Never overcharge the battery because it could spoil its function very smoothly. Keep an eye on how much energy you draw from the battery.
Even if your battery is capable of delivering 5 amps for 10 hours, you shouldn’t practice to drain it dry.
Make it up to the point of using only 75% of your charge at most. It might sound weird or superstitious, but it does end up doubling the life of some batteries.
- Never mix old batteries with new ones, never mix the battery types either.
- Charge the batteries immediately after you are done using it – if you leave them discharged for too long, it will decrease their performance and longevity.
- Although most batteries come with a maintenance-free label, you should still check the wet-cell battery fluids levels and top-off whenever needed.
- Do keep an eye on the terminal connectors every now and then for potential signs of corrosion. If by in case, there appear to be corrosions, clean it with a paste of water and baking soda.
- Always store batteries in cool and dry places, especially in the off-season and maintain a trickle charge.
Have you ever spoken to a fisher about their experience? They must have told you that patience and silence is the key to successful angling or fishing. The harsh truth is that the sound of motors, continuous vibrations and sputtering engines that scares the fishes off.
The quiet approach is what most fishers prefer, and that’s what helps them catch bigger fishes. To get the best catches, there has to be pin-drop silence, no vibrations or no exhaust fumes. Therefore, a smooth and easy electric powered trolling motor is all you need.

Also, trolling motors are made out of thick plastics and materials like stainless steel that’s resistant to almost any type of corrosion.
Thanks to the quiet motors that helps fishers catch more fishes in no time. Troll motors also make it possible to steer the boat easily rather than oaring the boat, which is more robust and less productive.
In a word, it’s a life savior. Smooth, relentless, silent, versatile and flexible, the trolling motor will change your fishing experience forever. With all our useful information and reviews on the best trolling motor batteries, we are sure you will find what you look for.
