12 Best Marine Battery For Trolling Motor Reviews Of 2023

Last Updated: May 9th, 2022 | By: Gina

What is the best battery for a minn kota trolling motor this genralized query by an angler requires a lot more to pondering over than expected, so lets delve into details.

The ability to carry the charge in the form of batteries has made every device compatible and handy. Trolling motors are popular among the anglers for its sheer ease of installation & operation,and trolling batteries are the natural equipment for using a trolling motor on a boat.

While Automobile batteries help in engine ignition and power other electronic parts, this light weight trolling motor battery is used in boats & jet skis and they just need to give an instant source of power for the engine to start.

A lightweight trolling battery is what’s most preferred for smaller boats but they usually lose their charging potential over the time of usage, so picking up the right trolling motor, is quite a task.

In the article below, we explore in detail the considerations required to decide the best trolling motor battery and how they fair among a dual purpose or a lithium counterpart.

Best Lightweight Trolling Motor Battery - Factors That Matter

The Battery Types

Mainly the three battery types and their suggested products are discussed in-depth below. There are deep cycle , dual purpose, and lithium-ion lightweight trolling motor batteries. All the three have different functions, battery capacity, power, and quality.

Deep CycleDual PurposeLithium-Ion

1. Deep Cycle Batteries

These batteries are designed to offer sustained power over a long period of time. Unlike a cranking battery these deep cycle marine batteries intend for deep discharges and charges and feature thicker plates for higher output thereby enduring vibrations.

The Two Most Common Types Are:

Wet-cell lead acid batteries:

These are popular and relatively inexpensive than the other battery types. But they possess a corrosive liquid electrolyte that could be dangerous, flows freely, and floods the plates. For eliminating this the batteries require topping-off with water frequently.

AGM Batteries:

AGM and wet-cell are similar as they both are lead-acid batteries. But one major difference is that the electrolyte is held securely in AGM (Absorbent Glass Mat) unlike the wet-cell. These are spill-proof, vibration-resistant, maintenance-free, and costlier than the wet-cell batteries. AGM batteries rate well on durability and performance.

2. Dual Purpose Batteries

These batteries perform a dual function and deliver like the starting and traditional deep cycle batteries.

These types of batteries are a perfect trade-off between the start-up demands for low-amp draw service of deep cycling and power the other electronics on boat for making you experience fishing the entire day.

3. Lithium-Ion-Battery

This is the lightest of all metals and has greatest electrochemical potential. For longest run time and lifespan we suggest these lithium trolling batteries because of following reasons:

  1. These are 70% lighter than lead.

  2. Offer a long life of 3000-5000 cycles.

  3. Require least maintenance.

  4. Need no memory

How To Choose An Ideal Marine Battery For Trolling Battery

When it comes to choosing trolling motor batteries, there are a few things you will need to consider: Battery type, battery amperage hour rating and budget.

Battery Type:

Depending on the transmission medium, chemistry, and electrolyte, there are four different batteries used for trolling motors i.e.

  1. Flooded Battery
  2. Gel Battery
  3. AGM Battery
  4. Lithium-Ion Battery

Choice of any of these batteries depends upon one's fishing condition, power requirements, charging cycles, and so on. In the above 4 mentioned batteries, flooded battery and AGM battery are the most common types of batteries available in the market.

Wet cell lead-acid batteries are the standard type of batteries that are pretty easy to encounter. The use of liquid electrolytes, usually in water, to flood the lead plates resulting in the most common form of battery used for ages.

Albeit, they weigh a lot and tend to be heavier than AGM. Plus, require more maintenance than any other type of battery. Corrosion is also one of the common issues that need to be addressed while mentioning the details of the battery.

Whereas in comparison, AGM deep cycle batteries are fully sealed and require less fluid maintenance. Plus, an AGM battery usually offers a longer lifespan as well, providing the worth of every single penny you are invested in.

Amperage Hours:

  • Trolling batteries are rated by Amperage Hours, usually abbreviated. Ah, a measurement of how long your battery will run your boat motor while it’s drawing a definite number of amps. It is typically best to go with the maximum rating you can manage, which will fit your boat.
  • If you have a 12-volt motor for a case, you will undoubtedly want a battery with the uppermost ampere hour rating you can use. As you only have one battery, you want to be assured that you can run your electric motor as long as likely without draining the battery.

Volt System Of Trolling Motor:

  • Electric trolling motor comes in three different power systems: 12, 24, or 36 volts. To make it simpler to understand, a 12-volt motor is run off of 12 volts marine battery.
  • For a 24-volt motor to work, it should be run off two different batteries, and a 36-volt type needs three.
  • If your boat is 16 feet or a smaller one, a high thrust 12-volt model will be acceptable for your encounter conditions. If your boat is a little long, moving up to a 24 or 36volt system is the only way to go for hassle-free boating.

Power/ Thrust:

  • Trolling or electronic motors, use battery power in command to propel a boat. The amount of strength or power required to move through the water is defined as “pounds of thrust.” This power rating is usual to all motors on the marketplace and is one of the most vital aspects to consider when choosing the suitable unit to match your craft. With inadequate power behind you, working your boat through wind, weedy conditions, or high waves can be all but impossible.
  • The thrust of a trolling motor is a very vital aspect to be considered for purchasing a battery. So, the requisite power from the battery depends on the trolling motor thrust. The amp hour rating of the trolling battery should be more if more thrust is wanted.

Boat Size & Weight:

  • Boat size and weight is an additional significant aspect to be considered while selecting and buying a good trolling motor battery. The additional size of the boat, the more thrust is needed, so more power is required. But more power doesn’t mean the battery is supposed to be large and heavy.
  • The area on the boat for the battery is a significant essential point. If there is less space for a battery, you must buy a smaller size battery. Adding extra weight to the boat might reduce its speed.
  • AGM batteries are not a decent option for smaller size boats with less space, as AGM batteries need stable mounting on the boat. So, ordinary small trolling motor batteries are the preferred choice for small size boats.

Size Of The Battery:

  • Like other factors, it is also one of the critical determinants to balance cost and quality. It could be subjective too, but experts usually suggest a direct correlation between the run time and the cost of the trolling motor battery.
  • In simple terms, the more the run time, the more expensive the battery is going to be. Follow a good rule of thumb that tends to provide a higher amperage rating, longer run time, keep all the other considerations at best.

Manufacturing & Warranty:

  • One of the most important aspects to be considered is the manufacturing date of the trolling battery. It would help if you always chose the latest trolling batteries. Plus, they assure you that the battery you are going to purchase is authentic and meets the quality standards; otherwise, they are ready to pay you back.
  • There are a few warranty periods for all kinds of batteries. You can at least expect a warranty period of 3 months or at a max of the lifetime. Some battery offers a full rated warranty, and some offer a pro-rated warranty. You should precisely review the warranty of the product.

Price Of The Trolling Battery:

  • Pricing of the battery is one of the essential elements before purchasing a trolling motor battery. Nowadays, there are varieties of batteries available in the marketplace at a wide range of price. It is not always correct that the high-level pricing battery is good. The truth is that even a high level may be disastrous due to the leaking of acids.
  • On the other hand, the truth is that the permanence of the battery depends on the attention and maintenance of the battery. It would help if you went for the most battery that is in reach with your budget.


Most batteries use an Amp Hour or Ah as a standard measuring unit. This measures how long a battery will maintain with a constant output. Majority batteries available in the market with come with this rating, that allows you to calculate an average lifespan of the battery:

  • Divide the RC (reserve capacity) by 2.4. This will help you to get the estimated amp hour rating.

For instance, a battery with1600 RC, will follow as:

  • Divide 1600 by 2.4, or 1600/2.4 = 66.6Ah.
  • The leading us to a conclusion that an ampere is how much electricity the motor will pull from the battery.
  • The max possible speed and thrust of the motor battery will determine the amount of energy drawn. For instance, 50Ah (amps per hour / 52 amps drawn = .96 hours of run-time on your battery.

How Long A Battery Can Run A Trolling Motor

Let’s Find Out

This happens sometimes that trolling motor batteries might be heavy to use, especially when it concerns inflatable sit in or sit on top tandem kayaks and boats. Even the personal pontoon boat owners get benefit from light-weighted batteries.

We Have To Understand This

The AGM batteries come with a good power capacity, and if they are light in weight then won’t be able to store more energy. With less energy storage the Amp rating per hour will belower as compared to the batteries of larger size.

Lightweight Trolling Motor Battery

The lithium batteries have 3 to 4 times less weight than the other AGM batteries. But the price of lithium batteries is very high.

The time duration a lightweight trolling motor battery can run a motor is dependant mainly on two major things:

  • The trolling motor thrust

  • Your speed setting

The batteries of light weight which range from 30-35 AH range can power motors which have around 35 lb thrust. The adequate strength is required before you can enjoy boat trip.

For calculating how long a battery runs a motor, the set-up has to be analysed

  • A Minn Kota trolling motor featuringa 30 lb thrust will be able to draw a maximum of 30 amp

  • An AGM battery of 35 amp

  • A battery of 50 AH also

The link can be referred to, for seeing the run time calculation

  • If you run the motor at a full speed, then it will draw a maximum of 30 amps in an hour. In this case the battery will be drained in a little more than an hour.

  • If the motor runs at half speed, then will be drawing 15 amps per hour, and the runtime will be approximately of 2:20 minutes.

  • If the motor runs at a low speed, will make it draw 5 amps per hour, and you will get a run time of complete 7 hours.

  • We can see that changing speed levels along with a light weight battery effects its runtime.

How Can A Trolling Motor Runtime Be Increased?

The battery usage decides the performance of a trolling motor. Personally, speaking a simple formula for this is - Performance = Usage.

Try To Remember The Undermentioned

  • Try not to run the motor at the highest thrust, as that will lead to the draining of battery very rapidly, and a capacity reduction of 10 to 15%.

  • You can set a motor speed of 2-3, mostly while using it. This will save your battery charge and won’t let it drain so quickly.

trolling battery runtime

  • The changing speed patterns speedily can also affect the performance of battery and the cost of power. It is advisable to change the speed gradually, rather than giving sudden twists.

The more we care; the more is the life of a battery. A well-maintained battery will give you more time to enjoy on the waters. Care well for your batteries, as you will be the ultimate benefiter.

The AGM batteries are supposed to be the best and come with a very low maintenance, rather we can say are maintenance free. A few more things to consider:

  • The battery should always be kept charged, while not in use. As there are chances of discharged batteries to sulfate. Henceforth, the capacity and service life of your battery will be lowered.

  • A good quality charger will certainly add advantage and the power supply of the charger should be around 10 to 20% of the amp hour capacity of the battery. A charger of 4-6 amp is sufficient for a 35 AH battery.

After following the above guidelines, you will be in a comfortable state to increase a trolling motor batteries run time and as well as maintain them with a longer life span. The performance and efficiency of the battery will also increase.

Benefits of Trolling Motor Battery

Trolling motor batteries have many benefits over daily life batteries, even on marine batteries. Trolling motor batteries are more reliable and credible. If you have the best trolling motor battery on board, then you can roam carefree almost everywhere, due to their heavy-duty performance. They’re bit expensive as compared to other marine batteries but gives a top performance, for which the other batteries are no match. There are oodles of benefits of having the best trolling motor battery, let’s have a look on them.

Durability & Credibility

Marine and other car batteries are not durable when it comes to heavy-duty. They may collapse and get damage due to type of use required in the boat. The positions at which the batteries are installed are also different so they may get leak or spill. The most important is the ability to absorb vibrations caused by the running of the motor. Common batteries are not made in a way to absorb them. But trolling motor batteries have electrically welded cases, which are way better than ordinary batteries. Hence they’re great at rough handling and use.

Deliverance of Charge

Ordinary batteries fail to deliver charge on a regular basis, there may be some fluctuation. Your motor requires an instant charge to get started, which ordinary battery fails sometimes. You may have to rotate the key several times to get started. But if you have the best trolling motor battery, this problem is solved. They’re made for heavy-duty, providing you charge in every situation. Discharging occurs at a continuous rate and charging takes fewer hours, with low electricity cost.

Deep Cycle

The feature that distinguishes best trolling motor battery from ordinary ones is the ability to deliver a full cycle, without any problem, and then get full charge again. The most battery may get heat up, or blast off, due to the pressure generated inside. A battery having a good deep cycle performance will last longer, give more power for an instant and will be durable. This happens because deep cycle batteries have a broader grid system within. This increases overall efficiency, performance, and abilities of the battery. A deep cycle battery is a better bet at tougher situations.

Trolling batteries have better cases, which help them to be spill-proof for longer time. The batteries are heavy due to these cases than ordinary batteries. That could lead to some handling problem but overall, they’re best for boats. If we consider cost, with other batteries, they’re expensive no doubt, but their performance, durability, credibility, charging time, everything is better. So you can invest in them hoping full-time returns. If you buy a cheap battery, you need to replace the fluid at a period of time; it may get fully dull, after some use, which may lead to buying a new one. So I would advise you to buy the best battery for trolling motor on the first only, as going for the cheaper battery is only going to cost you money later.


What Is The Best Battery For A Trolling Motor?

Trolling Motor needs special deep cycle batteries for best performance. These are heavy-duty batteries which offer power back up and unbelievable performance. It is completely different from the short cycle batteries i.e. the car or truck batteries. A short cycle battery can damage the motor and the battery. The batteries of the trolling machines come in three major sizes, based on their sizes- 12 volts, 24 volts, and 36 volts. Smaller boats can function perfectly with a 12- volt battery and bigger boats require one with 24 or 36 volts. The life of the trolling motor in the water will be for a longer duration if the voltage of the battery is higher. The battery should have a constant range of discharge, more lifespan, give the best performance using less power and which provides a high-quality design for deep cycle.

How to charge Trolling Motor battery?

The rate of charging and how long to charge depends on the size of the battery. Portable chargers are fully mobile, they need to be connected and removed. Modern chargers are quite good and are safer to leave connected to the battery for a longer time. It can be charged with the Onboard chargers which are permanently installed, wired directly to the batteries and can be connected to an AC power source to charge. Alternator chargers boost the trolling batteries while on the water. It takes excess power from the outboard alternator and delivers it to the trolling battery. The fully automatic battery charger is another method to charge the batteries after using the trolling motor and they won’t overcharge the batteries.

How to connect the trolling motor to a Battery?

The small and medium trolling motors use a single 12-Volt battery and larger trolling motors use 24 and 36-Volt systems. To connect a 12-volt battery to the trolling machine, connect the red lead wires from the motor to positive battery terminal and black lead wires to the negative battery terminal. For 24 and 36 volt battery, we will require two and three 12 volt batteries. To connect a 24-volt battery, connect the black wire from the motor to the negative battery terminal of one battery and connect the red wire from the motor to the positive part of the other battery. Use a 40-amp circuit breaker on the connection. Connect a jumper wire to the positive part of the first battery and the negative part of the other battery.
