Best 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.

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

Best Trolling Battery - Buying Guide

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 Requirements

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. To have a deeper insight into the difference among the different types of batteries.

Amperage Hours:

Trolling batteries are rated by Amperage Hours, usually abbreviated Ah. While this may seem puzzling, it is actually just 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 and that will fit in your boat. If, for a case, you have a 12-volt motor, you will certainly want a battery with the uppermost amperage 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.

Battery Chargers:

Just as significant as the battery it is the charging system an angler uses. It is not unusual for an angler with a hefty boat to use a 36-volt trolling motor. Though the Lithium-ion batteries do provide a 36-volt version, the usual angler will have an AGM or wet cell setup. This implies there will be three trolling motor batteries to charge. That can make it problematic to use a typical charger such as the one by which you can charge a car battery.

Similarly, if you are charging your batteries away from your home, you not only have to think of to bring your charger but also you will have to do whatsoever you can to make sure it is not embezzled while sitting in a parking area behind a hotel or anywhere else.

Volt System of Trolling Motor:

Electric trolling motor comes in three distinct power systems: 12, 24 or 36 volts. To make it simpler to understand, a 12-volt motor is run off of one 12 volts marine battery.In order for a 24-volt motor to work, it should be run off of 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 the conditions that you will encounter. 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.

Vibration Resistance:

While the boat motor is running, the base of the boat is clearly vibrated, so the battery will also vibrate. Every battery is prepared of plates that are placed in a specified manner, and the battery life depends upon the plates. When the battery is going on vibration and often vibrates, the plates inside the battery are moved and the battery starts slowly getting impaired. So, you should always choose a battery which is shock and vibration resistant.

Spill-Proof:

For the wet acid batteries and flooded batteries, dripping and leaking of acids is a very usual problem. The acids may spill and drips and may cause enduring damage to the boat or it may harm the wires that connect the motor. So, you should purchase a battery that is totally sealed and spill-proof.


Power Requirements

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 right unit to match your craft. With inadequate power behind you, working of 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. Thrust is comparable to power. 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 and 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 the more power is required. But the more power doesn’t mean the battery supposed to be large and heavy.

The area on the boat for the battery is an essential considerable point. If there is less space for battery you must buy a smaller size of a battery. You shouldn’t add an additional heavyweight to the boat, if the boat is already weighty, it also will slow down boat speed.

For smaller size boats with less space, AGM batteries are not a decent option, as AGM batteries need long-lasting mounting on the boat. So, Normal small trolling motor batteries are the preferred choice for the small size boats.


Other Factors

Fishing Conditions:

There are two situations of fishing, low water fishing, and deep water fishing. For shallow (Low) water fishing, the power necessity is less. But, fishing in deep water necessity is a high amount of power. So, for instance of deep water fishing, it is optimum to choose a high amp hour rating battery of your motor.

Weather Conditions:

The weather conditions are another important aspect to be considered. The water and the weather can disturb the run time and the performance of the battery. A trolling motor could draw 40 amps in windy and bad weather though it draws 30 amps at a usual speed in good weather. So, if you plan to fish often on the bad weather circumstances, then you must compute this factor before ordering a trolling motor battery.

Maintenance:

Some of the batteries like wet cell batteries need a lot of maintenance such as well-timed refilling of distilled water, monotonous inspection for an acid spill or terminal rust check, etc. On the other side, some batteries like gel, AGM and lithium-ion batteries are free from maintenance. The better you maintain the battery the longer life of the trolling motor battery you get.

Manufacturing & Warranty:

One of the most important aspects to be considered is the manufacturing date of the trolling battery. You should always choose the latest trolling batteries.

There are a few warranty periods of all kind of batteries. Some battery offers 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 the essential element before purchasing a trolling motor battery. Nowadays, there are verities of batteries which are available in the marketplace a wide range of price. It is not always correct that the low-level pricing battery is good. The truth is that cheap may be disastrous due to the leaking of acids.

On the other hand, it is not also always right that the costly batteries will last more. The truth is that the permanence of the battery depends on the attention and maintenance of the battery. You should go for the finest battery that is in reach with your budget.

Here are a few other things to be considered before making your final decision:

  • Composite or stainless steel shaft will undergo shock and stand up to manipulation much better than fragile metals.

  • Make sure the prop is weed-less, and the replacement blades are accessible for your exact model.

  • Ensure that the base is heavy duty and durable. The lesser amount of plastic parts it has, the better.

  • If you are planning on using the foot control pedal from somewhere in the boat, be assured that the cable is sufficient in length for the size of your craft.

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.
  • 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.

trolling battery runtime

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.

FAQ's

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.

How to replace Trolling Motor Battery?

Firstly, turn off all the switches. The negative cable should be removed and secured from making electrical contact. Then, remove the positive cable. The old battery can be exchanged or can be sent to a battery recycling center. 96% of the parts of the lead-acid battery can be recycled.

How Much Does a Trolling Motor Battery Cost?

No matter which camp you fall in, you should be prepared to shell out at least $75 and possibly up into the $300 – $400 range for a good battery. How much you end up spending on your trolling motor battery is going to come down to your personal preferences, what you value and your individual needs. Obviously, a more powerful battery is going to cost more, so people with bigger motors and lots of electronics that want to stay out on the water for as long as possible will opt for a higher-end battery.

Wrapping Things

We hope that the above suggestions will prove beneficial for you. Selecting the one that suits your preference is just one step away.

Make your boating or kayaking an unforgettable experience as the batteries we discussed about in the write-up above will never let you down. Do check the amp-hour rating, size, weight, type, and cycle life before you invest your hard-earned money.
