Built to Last
Sometimes you don’t want to go home. I get it; things can get complicated. A day out on the water is a lot more relaxing than dealing with the trials of everyday life. Deploying your kayak anchor into the water is one way of securing your spot.
However, what if you are a stop-and-go type of person? I know I am. Five minutes here and another five minutes further down the river.
It’s a great way of taking pictures, but having to haul your anchor onboard repeatedly is as annoying as it is tiring.
That’s where trolling motors come in. A trolling motor is a self-contained propulsion unit. They maintain your kayak in place without the need for an anchor. Better yet, they allow you to explore shallow areas. Other motors are not capable of this.
To power such a nifty tool, you are going to need a trolling motor battery.

Kayak Trolling Motor Battery Types
Are you tired of reading about trolling motor batteries yet? No? Good, because now I am going to break down the main types of trolling motor batteries on the market. This section will further your understanding of the batteries listed above.
Each trolling motor battery type will vary not just in performance and longevity but also in recharge times and whether they are rechargeable at all.
I should also mention that a battery’s size and even the number of cells that each battery has is all dependent on their type. There are three main types; let’s quickly run through them.
Wet-cell Batteries
As far as rechargeable batteries go, wet-cell batteries were the first on the scene. From here, all others came. Now, this doesn’t mean that all wet-cell batteries are archaic, but you should note that other types are more likely to have design advancements.
So then, why the name “wet cell battery”? The reason why this type of power source is called a wet cell type is that they are filled with a liquid electrolyte. That liquid electrolyte being sulfuric acid.
Yes, the highly dangerous and extremely disastrous sulfuric acid. How can you tell whether you are in possession of an acid bomb? Simply shake the motor battery, and if it is a wet cell battery, you should feel liquid sloshing around inside.
AGM Batteries
Perhaps starting off this little section with wet cell batteries wasn’t the right choice. However, I assure you that AGM batteries are not as scary sounding. The AGM stands for absorbed glass mat.
Okay then, what is an absorbed glass mat, and how does it affect this battery type? AGM batteries have a special glass mat that acts as a divider. Its job is to wick any electrolyte solution that may appear between the actual battery plates.
What this results in is a design that removes the need for a liquid-form electrolyte. This is because the electrolyte is able to be stored in a dry form thanks to this mat.
It’s a safer version of what was listed above.
Lithium-ion Batteries
Lithium batteries have taken the world over since their introduction. They are reliable and efficient, capable of generating more power than other battery types. This lithium battery type is rechargeable, and it uses lithium ions to store its energy. Hence the name.
A lithium battery is generally more powerful and smaller than other battery types.
This makes lithium battery perfect for a smaller trolling motor or small boats. Not just because it’ll take up less room but also because they tend to weigh less than other options.
The best part about a lithium battery is that it is resistant to natural discharge. You won’t have to worry about any leaks or dangerous outbursts damaging your boat or yourself.
Safety First! What to Keep in Mind
I can’t stress this enough; please be careful when handling any kind of kayak trolling motor battery. Whether you have a deep cycle battery or have jerry-rigged multiple trolling motor batteries into place. These devices are often filled with toxic and hazardous chemicals and materials.
In the case of sulfuric acid wet cell batteries, well, the name speaks for itself… doesn’t it?
This is why you should handle your motor battery with extreme care. Keep a close eye on how much time you charge your motor battery. A marine battery must be properly charged, it’s not like a phone battery.
Marine batteries can be overcharged. When this happens, watch out! A marine battery that is overcharged will have its chemical energy turn into blazing hot heat energy. Keep all that bottled up, and eventually, it will explode!
One thing you should never do is lean over any battery that is charging or in use. Whether it is a motor battery or a car battery. Having protective eyewear on whenever you set your battery to charge or whenever you are hooking it up is also smart.
Safety goggles won’t be able to protect your entire face. However, they will protect the most delicate and important part of the face itself. One last thing to keep in mind, always inspect your trolling motor batteries for any visible damages before charging it or using it.
Buying the Best Trolling Motor Battery for Kayak
Usually, I suggest that one know all the specifications and how they affect the equipment’s performance before making a purchase. However, when it comes to an AGM trolling motor battery or kayak trolling motors in general, so much more is on the line than just performance.
This is because whatever kayak trolling motor battery that you settle on, may not be the right fit for your motor. For example, lithium batteries aren’t usually suited for trolling motors. They are too powerful, and your motor can get damaged from their higher energy output.
Consider the following before making a final choice.
Deep-cycle/Marine Battery
First up on what you need to know to not make a grave mistake, we’ve got deep cycle marine battery. What is a deep-cycle marine battery? In the world of kayak trolling motor batteries, your battery can either be a cranking battery or a deep-cycle marine battery.
The deep cycle is another word for trolling. What’s the difference? A cranking battery is focused on starting up the engine or motor. This battery type aims to get your kayak or boat going from a zero starting position.
A deep-cycle battery keeps your kayak’s motor going. Any electronics or energy drainers are all hooked up to and dependent on the deep cycle battery. I know what you are thinking, “Great, one battery complements the other!” Not exactly.
While a kayak can have both battery types on board. You must keep in mind that the starting battery will quickly run out of juice when paired with a deep-cycle battery. Not to mention that a deep-cycle battery will also have to burden some of the energy cost for getting the kayak motor started.
Rather than complement each other, they get in each other’s way. Be sure to choose one and only one. Don’t mix them, there is no point in that.
The Size of Your Motor Battery
Size is a relatively easy concept to understand. In some cases, bigger is better, and in others, not so much. First, I’ll be going over the more obvious things to know about a battery’s size.
A battery’s size will have a direct impact on how much it weighs. The more it weighs, the heavier your kayak will become. This means that your kayak’s motor will have to put in the extra work to keep you moving along the water.
This, in turn, means that your trolling motor battery will have to kick it into overdrive to satisfy the needs of the motor. Don’t you just love chain reactions and their constant desire for escalating any situation?
A kayak trolling motor battery doesn’t usually take up much space. So you won’t have to worry too much about this aspect unless you are traveling in a shoe box.
Besides the obvious weight and space effects, the size of a trolling motor battery also determines whether it is even compatible with your motor to begin with.
An undersized battery will struggle just to get you moving at a snail’s pace. Be wary of trying to slim down. It could negatively impact your performance in the end.
Battery Weight
I touched on this aspect a bit in the previous section. To summarize quickly, battery weight affects the weight of the entire kayak, which in turn affects how much energy is needed to move it. However, that is not all that a battery’s weight can affect.
The weight of a battery will also determine how much power it packs. This is a pretty simple thing to keep in mind.
The more it weighs, the more power is at its disposal. The amount of power a battery contains will affect many things. Chief among them is the battery’s charge time and its amp hours.
However, I’ve got two sections down below for these two specific topics. As a result, I won’t be getting into them here. You may not think that a battery’s weight is that much of an issue, but consider the following.
Suppose you’ve got a guest on your kayak with you. You start the trolling motor to help you move along. Except, you notice that your kayak is sunk further into the water than it should be.
Uh oh! You’ve reached your kayak’s maximum weight capacity. What to do now? You can’t throw your friend overboard. I mean, you can, but you shouldn’t. A lightweight trolling motor battery would have spared you from having to throw anything out of the kayak.
Charging Time, How Long Is Too Long?
In a world constantly hooked on to electronics, one battery attempts to satisfy all by full charging in only a matter of minutes. Now that would be one great battery. The only problem is that as far as trolling motor batteries go, it doesn’t exist.
Charge times are important because they determine how much time you’ll have to spend on the sidelines. Patiently waiting for your battery to be fully charged like my cat patiently waits for his food. It’s torture.
How fast a battery will charge depends not just on each specific brand and model but also on the type of battery. For now, lithium-ion batteries tend to be the fastest charging. The issue with them is that they may be too powerful for your motor to handle.
Potentially damaging your trolling kayak motor for a quicker recharge doesn’t sound like the fairest of trades. Keep in mind that most deep-cycle batteries will fully charge in ten to twelve hours.
Sounds like a lot of time, but it’s nothing that an overnight charging can’t handle.
Amperage Hour Rating
A battery’s amp hour rating is the amount of energy from a battery that is used to release one ampere of current for one hour.
Sounds complicated, huh? Yeah, I had to look this up myself. Pretty much what this means is that an ampere-hour rating tells you how much amperage a battery can provide for the duration of an hour.
Amperage is the strength of an electric current. To further break down this unnecessarily complicated subject. This rating determines how long your battery will last with each full charge. That’s right, a battery’s life per charge is mostly determined by its amperage hour rating.
The higher the AH rating that your trolling motor battery has, the longer its runtime. All is well and good except for one thing. I don’t want you to get confused and assume that an AH rating also has something to do with how much power your battery has.
No, this rating has nothing to do with the battery’s performance power. Only the battery’s actual life per charge is affected by this. Of course, the motor of your kayak will also play a role.
Stronger and more modern motors will drain your battery much quicker than older motors.
FAQs
What Is a “Battery Reserve Capacity”?
A battery’s reserve capacity is the amount of time, which is categorized in minutes, that a twelve-voltage battery can last before dropping down to a ten-point five-voltage battery. Hence the word reserve in “battery reserve capacity”.
It’s important to know this because it gives you a general idea of how long you can count on your battery’s maximum potential. By maximum potential, I mean how many amps can be supplied and for how long.
What Happens If the Battery Gets Wet? Should I Protect It?
Let me answer the second question first. Yes! You should absolutely protect your battery from the elements, especially water. If too much water is added to your lead acid battery, then you can expect a massive performance drop.
Not to mention that this excess water will cause the electrolyte levels to spike. Resulting in leaks, overflows, and serious damage.
If your trolling motor battery does end up getting wet, dry the housing and terminals. Water will always deteriorate marine batteries. This is odd, you’d think something with “marine” in its name would be able to handle a few splashes of water.
How Often Should a Trolling Motor Battery Be Charged?
I’m sure you’ve read all kinds of random things on the internet. You know, the weirdly specific ways to maintain your battery’s longevity.
“Only charge for one hour” or “only charge once the battery has completely died.“
The truth is that you should charge your trolling motor battery after every use. How long it lasts will depend on your motor and the motor battery itself. If you haven’t used the battery in a while (more than two weeks), then you should also charge it.
My Final Thoughts
Sometimes, slowly trolling through the water is better than trying to be an Olympian. Paddling is tough work, and if you can get a quality trolling motor battery to lighten the load, then you absolutely should.
Remember that each battery type comes with meaningful pros and cons. Wet cell batteries contain sulfuric acid, but they tend to fit with any trolling motor.
Lithium Ion batteries are powerful, but if you’ve got an older motor, your motor may not be able to handle the extra juice.
An AGM battery is a reasonable middle ground. Whichever trolling motor battery you end up choosing, be sure you know how to handle it.
