You will need to get an appropriate trolling motor ready on your boat if you want to keep on moving along the water. The best trolling motor battery can make a real difference when you are looking for something worthwhile. A great trolling unit will come with a quality electric thrust motor and propeller as well as the necessary controls needed to keep it operational.
Such a motor is ideal for when you are trying to go after pelagic fish. With this motor, it becomes easier for you to slowly drag the bait you are using behind your boat. This may help you with finding fish and can even entail your bait sweeping the side all the way through depending on how you lay out the bait yourself.
But the problem with many trolling motors is that they are gas-powered. You need to stick with an electric motor that can potentially last for a longer period of time and will not make as much noise as a gas-powered model. An electric motor is also cleaner and should not disrupt the water quality in the spot you are fishing in.
Your trolling motor will need a quality battery for it to work through. There are many choices you can look for when getting a trolling motor battery ready for your use. Each works with its own features and can run for hours at a time depending on what you order.
Also, some of these batteries are better suited for certain types of boats. This is based on how large those boats are and how much power they can handle at a given time. Look carefully to see what is available when finding the best trolling motor battery that fits in with your needs.

You must look at how well a trolling motor battery is designed when finding something of value. Each battery on the market is designed with its own distinct features.
You should know how to compare each of these points with one another to get an idea of what you can expect out of a quality motor. You should not have much trouble finding the best trolling motor battery for your needs when you look around to see what is out there.
Our post about how to mount a trolling motor can be handy for those who want to know, especially for beginners.
What Is the Lifespan?
The lifespan of your battery needs to be reviewed in many ways. In particular, you would have to look at both how many years it can last and also your plans for using the battery.
A battery can last for two years or more in most cases, but you should expect to get a new battery after about five years. At this point, the electrolytes in the battery will have worn out all the way.
The lifespan might be a little longer if you do not use the battery that often. Still, you would use it to test the battery on occasion and make sure it is stored properly so it will not prematurely lose its power and charge. Add it to your checklist for boat winterization.
Watch for this when seeing how well your batteries and can handled and that you know what you are getting out of them.
Review the Amps
Start looking for a battery by reviewing the amps that come with it. A battery is measured in amps, a total that measures the charge inside the battery that allows an amp of current to discharge over an hour.
The main point is that a battery with more amps or amp hours will hold more electricity. Smaller trolling motor batteries can handle about 25 to 50 Ah of power. Some of the largest options can work with 100 Ah of power.
The amount of power that will be used up by your battery will vary based on how fast your boat goes or how large your motor might be. You will use more power if the boat goes too fast or the motor is rather large and requires extra effort for powering it up.
Check the Power System
The way how a battery is powered up should be checked accordingly. A battery can come with a 12-volt charge for the most part. This should be enough for an average motor, but you might need to get multiple batteries linked up together just to start something a little larger in size.
You will not be likely to find any batteries that work with more than 12 volts of power at a time. Be aware of what you are coming across when finding such a battery so you have a good plan for making it work.
What Is the Weight?
The weight of your battery is important to look at. Some trolling motor batteries can weigh around 25 pounds while others could be 50 pounds or more in weight.
A heavier battery might contain a better charge, but it will also create an extra bit of drag on your boat.
The battery weight, in this case, does not include the wires, mounting features, and other items you would require to make it work accordingly. Check out what is available for your use so you can get more out of your work.
Review the Wires
The wires that are used on your battery should be coated well enough without exposing anything that might be fragile. But for the best results, it helps to keep the wires from being too long.
The wires should be short enough to confirm a better connection all the way through.
Don’t forget to check the wires if you want to have a second-hand boat.
Wet-Cell or AGM?
When finding a trolling motor battery, you will more than likely come across one of three options.
A wet-cell battery is a more commonplace battery that can last for about two years on average. This battery works as one where the cells or plates inside of it are doused in electrolyte fluid, hence the “wet” name. Water and sulfuric acid are typically used in a wet-cell battery.
You would have to regularly fill the battery with water to allow it to handle its full charge. You would have to do this every six months to keep the battery cells from wearing out or suffering from extreme damages.
Also, a wet-cell battery is susceptible to damages from vibrations and other physical impacts. Still, one of these batteries can be found for pretty cheap on the market and might work well when you are trying to get somewhere where the water is not all that rough.
An AGM battery is an absorbed glass mat unit. It is fully sealed and does not require any maintenance. It will not be hurt by vibrations or most other forms of pressure either.
It can last for about twice as long as a wet-cell battery too. Still, it will cost significantly more money than a wet-cell model.
A series of glass mats are used inside an AGM battery to keep the electrolytes in. No fluids are needed in this model. A full weave is used on the glass mats to use thin glass materials that link up well to keep electrolytes in without potentially leaking.
An AGM battery may also be called a sealed lead acid battery or valve-regulated lead-acid battery. These are all the same things based on how they work.
Gel-based batteries are not as common as what you might find elsewhere. Such batteries include a gel-like surface that features sulfuric acid and fumed silica alongside pure water.
The gels keep leaks from developing in the event of any damages to the battery itself. Also, the charging process produces both hydrogen and oxygen, thus ensuring that the water stores in the area are maintained well.
This takes a bit of extra time to charge up as it operates at a low voltage level. It is not all that easy to find such a battery due to the complicated process required for getting the gel prepared here.
Most of the batteries you will find today are AGM batteries. You can find many other choices for all your requirements if desired, but it helps to look at your needs for fishing to see what is right for you.
Identify Maintenance Points
The good news about most of today’s batteries is that they do not require all that much maintenance. They are made with solid bodies and are typically not at risk of leaking.
Still, you must watch for the type of materials that your battery uses. A wet-cell battery is a good example of this. You would have to regularly add water to that battery just to keep it working properly.
Also, a battery might develop corrosion over time. This corrosion can be dangerous to the battery as it will prevent a proper charge from coming along over time.
Make sure you look at how well your battery is working in any situation. You might have to take a careful look at how well the battery is working and that its body is intact at all times.
Always avoid using any battery that you feel does not appear to be fully charged or ready for use.
Each battery manufacturer should have its own warranty that you can use for getting the most out of your work. A warranty should last for about a year or two.
The warranty should also cover regular charges relating to the standard use of the battery. You might end up voiding the warranty if you are overly abusive on your battery or you try to modify it in some fashion.
Also, the warranty might be paired with a guarantee. This can include a 30 or 45-day guarantee where you can return the battery for a full refund if you are not satisfied with that model.
The best trolling motor battery should be something that can fit well onto your boat and not add more pressure or issues than what you are comfortable with. But the size of your battery should be reviewed based on more than just weight.
The battery can be around six to twelve inches in size on its longest or widest parts. A battery needs enough room to hold all of its parts, but you might struggle to get the battery loaded up in the middle of a good mount.
You should check on how well the size of your battery is made while also finding a battery mount or other surface that can work well enough for keeping it in its place.
Some batteries might include their own mounting materials made specifically with their bodies in mind, but this feature is not always easy to find.
Be aware of the noise level that is produced by your battery. Most deep cycle batteries should work with very few vibrations and noises, thus ensuring it can work effectively.
When the noise level is low, it becomes easier for the battery to work while the fish in an area will not be at risk of running off.
Terminals for your battery should be made with strong metal materials. Some models might come with holes for securing wires onto them.
Others have cylindrical bodies for the same intention. The terminals should be easily labeled between positive and negative ones so the battery can be appropriately charged as needed.
A battery’s ability to keep its terminals clean and easy to maintain is vital. However, sometimes the terminals might develop corrosive materials. The corrosion on the terminals will keep them from working as well as usual.
The corrosive surfaces are caused by hydrogen gas being released from the battery’s acid. The overall connection between lead and copper around these spots can also produce some corrosive residues. These materials can be cleaned off when you mix water and baking soda over their surfaces.
The best trolling motor battery is always one that is fully cleaned off and is not going to bear any sudden issues that would keep it from having a full capacity.
Marine batteries typically do not have their own switches. The power that a battery produces will automatically move out to the devices that you are trying to power up on your boat.
But you can always get an outside switch ready if desired. An outside switch may attach to your battery and allow you to turn the battery on or off as desired. You can use this if you are trying to keep your battery from using more power than what you can afford to use at a moment.
Brands to Look At
The brands that you can utilize when getting a trolling motor battery include many choices that will help you keep your boat moving.
You can find batteries from many companies like Minn Kota, Universal Power Group, Interstate Batteries, Mighty Max, Optima, and VMAX among many others.
When finding a good provider, you have to find one that has a good reputation and a decent variety of products for sale.
Take a look at what a company does when seeing what its brand has to offer so you will not be surprised or at risk of getting into any issues when trying to find something of value.
The cost of your battery should relate to the overall power being produced by the battery. A 35 Ah battery can be found for around $60 to $120 in most cases. A 100 Ah battery can go for closer to $150 to $200.
Although such a battery is cheap to get when compared with the value of the boat itself, you should still make sure you spend a proper amount of money based on how powerful your battery is.
Frequently Asked Questions
The following section entails a series of questions you can use for figuring out what you can get out of your battery. Be sure to recognize many of the points that come with getting one of these batteries ready.
How can one of these batteries work?
A battery will work by allowing the positive and negative terminals inside the battery to read one another. The connection between the two ensures that enough ions move around to create a strong current.
Over time, the positive ions will move out to the negative pole to create the energy you need. This can work so long as there is enough of a charge inside the battery.
How can a battery be charged up?
A trolling motor battery can be quickly charged up through a traditional charging station. Depending on what you order, you might have to get a battery charged up by plugging it into the appropriate station that links to a power outlet.
This should help you with getting the battery charged up and ready to work again. But be advised that the battery might take a few hours to charge up, what with it requiring a sizeable amount of power for it to work accordingly.
Is it fine to keep the battery in a charged position after it has gotten a full charge?
Although some people like to do this with the belief that the battery might start discharging on its own after the power source is removed, this is actually dangerous.
Sulfide damage might develop on your battery if you leave it charged for far too long. This keeps the electrolytes inside your battery from working as well as they should. This causes the battery to lose power over time.
How much time should you spend cooling off the battery after each charge?
Give your battery a full day off to cool its body if possible after charging it. The heat that is created during the recharge and discharge systems can become intense.
Using the battery not long after all that heat was generated could potentially put the battery at risk of harm. Avoiding using the battery for a bit after you are done charging it is often the best thing to do in this case.
Why is the battery not working with enough power during its first few uses?
Your battery will work under its maximum capacity during the first few times that you use it. It may charge about 20 percent less than what it can handle at the most.
The plates inside the battery have not been fully formed or connected at the way at this point. This means that the battery might not work as effectively as it should. Make sure you review the battery after each use and that it is operating to your liking.
Can many types of batteries be mixed with one another?
You should never try to mix different types of batteries with each other at any time. Doing so may cause the battery you are using to wear out.
Not all kinds of batteries may be compatible with others. These include batteries based on size and brand among other vital points of value.
Can older batteries work next to new ones?
Always use new batteries when replacing them. You should not replace just one battery if you have several at a time.
All batteries should be replaced when getting new ones added no matter how many batteries you are getting rid of.
Can a battery work in most water conditions?
Many batteries can handle numerous types of water, but you must be cautious if you want to bring your boat out to a salt water space.
A battery needs a stainless steel and zinc base to ensure it will not be at risk of harm from salt water.
What does a deep cycle battery entail?
A deep cycle battery features a design that will be deeply discharged with much of its capacity utilized in the process. This is different from a starter battery that delivers short bursts of energy when getting an engine started up.
A deep cycle marine battery is not going to produce as much power as other traditional batteries would. This ensures that the battery will keep on working to your liking. Also, the battery will not produce as much noise, thus ensuring that the waters will stay calm.
Most of the trolling motor batteries you will come across are deep cycle batteries. Some can handle starter functions as well. Check on the features of any battery you wish to order to see how well it can handle energy.
How can you tell how much energy is left in your battery?
Some battery models come with LED displays or other lights that give you an approximate idea of how much power is left on your battery. You might want to bring a battery testing unit with you just in case so you can confirm the charge on the battery.
Such a tester requires you to secure clamps onto the battery terminals and then use a test charge on it. This gives you an idea of what you are getting off of your battery.
You also have the option to add a separate LED battery indicator to your unit. This can be attached to a terminal. It would then spend a few bits of time waiting to get information on how much power is left. This gives you a good idea of how much power is in your battery, but it might also be a rough estimate of what you can get from it.
How long will your battery work for before it dies out altogether?
A battery should work for about two years at the least before it dies off. Some batteries might last a little longer if they are not used too often or have not gone through as many cycles.
The overall lifetime of the battery will vary based on what you might use and how well it can work for your desires.
How much energy should be used in the battery before you have to turn it off all the way?
The best rule of thumb is to avoid discharging more than 80 percent of the battery’s content. Although you can allow the battery to charge it up even further, you might risk the battery not working properly due to the electrolytes becoming prematurely dry.
Keeping a small bit of power inside the battery before it can be recharged also ensures that you have enough of a base to work with as you start getting everything charged up again.
Is the total number of cold cranking amps on the battery going to make a real difference?
Cold-cranking amps are not all that vital in most cases because many of the batteries offered are designed with smaller motors in mind. In fact, a majority of battery companies do not actually list information on how many cold cranking amps are produced.
The point is that most of these batteries are made with enough amps to get the motor started up well enough the first time around. They are not necessarily made to work for larger vehicles or boats that would require more of these amps at a time to get them ready to work.
Are the terminals at risk of corroding?
All batteries could develop corrosion on their terminals regardless of what they are made of. Always review the terminals regularly to see if they have worn out. These might have to be cleaned off, but sometimes it might also show that the battery is wearing out and needs to be replaced altogether.
How can you clean off the outside body of one of these batteries?
To clean off any spills or even any corroded parts, use a mix of water and baking soda. This should produce a paste that can clear off even the most stubborn bits of your battery.
Can a trickle charger be used on a trolling motor battery?
You can use a trickle charger by linking its parts to a series of ports. This can keep the battery from fully discharging while in use. Be sure to remove the trickle charger after a while though. Leaving it on for too long can result in the battery possibly being damaged.
Is plastic okay for a battery’s body?
Plastic should be fine provided it is thick enough and engineered to handle the vibrations that will come about as you use your boat. The plastic should be light in weight and capable of fitting over the cells the right way.
How is the carry handle on one of these batteries made?
The carry handle on a battery should be made with a sturdy plastic material that will not bend or crack easily. But since these batteries are often twenty pounds in weight or greater, there is always the chance that a battery’s handle might break apart.
Although a battery should be made to handle vibrations, you might be better off carrying the battery from the bottom if you are able to.
What is the ideal temperature for use?
A trolling motor battery can work in many conditions, but it is best to use it from 60 to 80 degrees Fahrenheit at a time if possible. Anything too hot or cold might make it harder for the battery to actually work to your liking.
Why is a battery only developing corrosion on one terminal but not the other?
Your battery might not be charging properly if you notice corrosion on just one terminal. When the corrosion is on the positive side of the battery, it means that the battery is overcharging itself. When the corrosion goes on the negative side, the battery is not charging well enough.
Can any motor battery work with any kind of bait?
You can use a trolling motor battery no matter what type of bait you will use. You should still choose that bait based on how powerful your motor is and that it is not going to be hard to utilize in any fashion.
Can a battery work for any type of motor?
Although many marine batteries are used for other needs, that does not mean that they are good enough for other items. Some marine batteries might not be powerful enough to get a larger RV motor ready.
Others could be too strong for a golf cart and might cause excess heat if handled improperly. For example, a battery used in trolling motors for pontoon boats may not fulfill your other types of needs.
The best thing to do is to avoid using your trolling motor battery on anything other than your boat. This is to prevent significant problems that might come along due to there being too much power on your boat at a given time.
Having a battery is essential in that it does more than just ensure that your body can stay propelled and ready to move forward. It also makes it so your boat will stay active and ready to move. You need a great battery so you will not be at risk of getting stranded in the middle of the water because you ran out of power.
You must know what you are getting out of a trolling motor battery if you want to get out on the water and enjoy everything it has to offer. A useful battery will last for a while and can power up your boat motor with ease. But it must also be built to last and should handle the water conditions you enter into.
Whatever the case may be, the battery you order has to be designed to be easy to handle without being overly rough. You should not have to worry about far too much maintenance when getting it ready and safe. When used right, you will get more out of a quality battery that is strikingly helpful and ideal for your boating demands.
