Factors To Consider When Looking For The Best Trolling Motor Battery

There are a few important things that you need to consider before you buy any battery. Now that you have a list of the best trolling motor batteries and are close to buying one, you need to focus on some aspects.

But before looking at the important factors, you should determine how you will use the battery and how frequently it will be used.

Once you answer these questions, here is what you need to think about:

Different Types Of Batteries

Trolling motor batteries are specifically designed for a trolling motor of fishing boats. They are used for providing power to the boat while the angler trolls through fishing areas slower than usual.

There are many different types of batteries that can be put in motors for trolling. Here are some types of batteries.

Dual-Purpose Batteries:

Image of a dual Purpose battery

These batteries are ideal for providing power to the engine, turning it over, and keeping the motor running even while the angler slowly fishes. It can be used for both purposes.

Deep Cycle Batteries:

These batteries are different than dual-purpose batteries. You can easily find the best deep cycle battery for trolling motors from the batteries we reviewed.

Image of Deep Cycle Batteries for boat

They are made to provide a steady level of energy to trolling motors for longer durations. Therefore, deep cycle batteries are ideal providers of exceptional performance while fishing. Additionally, these batteries last longer than other batteries.

Lead-Acid Wet Cell Batteries:

These are the most common type of batteries to use in trolling motors. They are a great affordable option that is ideal for daily use. They usually last 2 to 3 years with good care and maintenance. The wet cell battery refers to the battery cells plunged in the water and sulphuric acid mixture.

Image of a Lead Acid Wet Cell Battery

However, one thing that requires care in these batteries is the risk of over-charging, decreasing the water levels, and burning the cells. Therefore, I recommend that you check the battery before using and if the water is low, you add distilled water to it.

AGM Batteries:

Image of AGM Battery

AGM stands for Absorbed Glass Mat; these batteries are sealed, unlike the lead-acid cell batteries. They are also expensive than most batteries, but a good thing about them is that they don’t require maintenance and will last 3-4 years.

Lithium Batteries:

Lithium batteries are better than all the batteries that we mentioned. It is the ultimate option when you are looking for an all-rounder battery. They are superior to lead-acid and AGM batteries because they have a long life span.

They have abilities to deep cycle batteries while maintaining themselves and not requiring any maintenance. They can work 10x better than other batteries and provide 80% good performance for 2000 miles. Their charging time is also minimum, which will make your adventures a hundred times better.

Voltage And Amp Hour

The most important factors to look for when buying the best battery for trolling motor are its Amp Hour Rating and its Voltage Capacity. Both these things determine how much power your motor will get at what rate and for how long.

Amp Hour Rating is like a fuel tank gauge; it regulates how long a battery will last. It gives an amount of charge to your trolling motor battery. The higher the number of amp-hours, the longer your battery will power the motor.

The recommended battery time is at least 100 amp-hours before the battery is put into use so that it won’t stop working in the middle of your trip. However, if the amp hours are higher than the battery will last longer.

The best deep cycle battery for trolling motors has about 12 volts. However, you must check your system if more voltage is needed and then buy the battery according. Some motors also require 24 volts or even 36 volts.

Construction, And Maintenance

All batteries are constructed in the same way with a few different components. There are two plates with acid, separator, electrolytes, plastic, and rubber.

The plates are separated by a separator which is an insulator. The construction is done in a hard plastic body so that it can bear the electrolysis.

Image of four different types of batteries

If you wish to keep your battery lasting longer, you have to regularly give it a maintenance check. Here are a few ways by which you can do that.

  • You should recharge your battery as soon as you can after a fishing trip because if a battery has less than 12.5 bolts, it can form lead sulfate inside the walls. This can reduce the life and performance of the battery.
  • When you are not using the battery for a longer duration, you should tickle charge it to keep power flowing through it to keep it working.
  • Fully drain your battery and recharge it entirely once in a while. Because the chemicals are out of balance and the acid sinks to the bottom, recharging it fully will restore the balance to the battery.
  • Allow the battery to cool off after charging because it produces a significant amount of heat, and using it immediately can permanently damage the battery.

Cold-Cranking Amps (CCA)

Cold-cranking Amps (CCA) is a term from the battery manufacturing industry used to describe rating and a battery’s ability to jolt a motor when it’s cold.

The CCA measures how much current/power can be delivered by a fully charged and new 12V battery in 30 seconds while maintaining volts of 7.2V at a temperature of -18⁰C (0⁰F). The current is measured in Amps.

The cranking power varies from motor to motor, which is required to start a motor. It is affected by various things like temperature, motor size, oil viscosity, etc. Usually, for every cubic inch of motor, it is one cold cranking amp.

The Cycle Life & Battery Size

Just like any other battery, the fishing trolling motor batteries decline with use. This happens because of the chemical and heating procedure inside a battery when used and charged. The lifespan of a deep cycle trolling battery depends on the type and quality of the battery.

Image of black motor battery

Lithium batteries are the best marine battery for trolling motors. They are one of the most durable batteries having a lifespan of almost ten years.

An AGM trolling battery can last up to 2 to 4 years, while lead-acid batteries can last up to 2 to 3 years. All these lifespans greatly depend on the maintenance and quality of the batteries.

Since you have limited space on your boat or canoe, the size of the battery is very important. When choosing your trolling motor battery, you should go for a size that will easily fit in your boat without taking up a lot of space.

You should also consider the weight of the battery because you have a limited weight allowed on the boat. Your battery should not be heavier than 20 to 70 pounds.

Durability & Vibration Resistance

The durability of the motor trolling battery depends on the maintenance and quality of the battery. However, remember that no matter how much you take care of your battery, it will wear out after a few years of use.

It will go through various wear and tear, which will affect its performance over time. The best way to estimate when your battery will subside is by checking the battery’s lifespan date.

@SmallBoater

Since we are talking about durability, the most important thing that affects durability is the resistance to vibrations and shocks. This happens because a battery used in the sea for fishing is exposed to many shocks, damaging it.

That is why it is important to buy a battery that uses AGM technology for excellent vibration resistance. The details of vibration resistance will be mentioned on the packaging of the battery.

Tips for Maintaining your Trolling Motor Battery Life

Your best marine battery for trolling motor is as good as you maintain it. It will perform well and have a longer life if taken care of and used with care.

But, if you are not sure how to take care of it, then here are a few battery maintaining tips for you.

  1. Recharge as soon as possible after each use: you must charge the battery after spending a day on the water. Because leaving the battery on low volts for longer durations can affect its performance and lifespan.
  2. Use the exact charger onboard: every marine battery has a charger that comes with it from the manufacturer. I recommend that you use the approved charger for charging the battery so that your battery is free from getting damaged.
  3. Keep the terminals clean: the quickest and easiest thing that you can do to maintain your battery is to keep its terminals clean with baking soda and water to keep away corrosion.
  4. Maintain water levels: when you use a battery, the water in it evaporates, leaving only acid behind. Raw acid can harm the lead and cells of the battery, and that is why it is crucial to keep the water levels up with distilled water in your battery.
  5. Charge batteries when not in use: leaving the battery cold and unused for long durations can affect the lifespan of your trolling battery. Therefore, you should charge and discharge it once in a while to keep it running.

My Final Verdict:

Hopefully, the reviews and guidelines about the trolling motor battery will prove helpful for you. The battery is a critical and useful component of any fishing trip, and it needs to be perfect for your trip to go perfectly. If you have any issues, you can follow this guide and go through all the reviewed batteries to find the perfect one.
