What Are the Different Types of Trolling Motor Batteries and Their Advantages?

There are different trolling motor battery types considering technology and applications. Depending on the application, you might find a starter, deep-cycle, or dual-purpose battery. Starter batteries are not suitable for trolling motors, meaning you should only choose a deep-cycle or dual-purpose battery for a trolling motor.

The technology of a battery for a trolling motor is defined by its chemical core, which in turn defines its advantages. These are the best trolling motor battery types available in the market.

Flooded Lead-Acid Wet Cell Battery

A lead-acid wet cell battery, also known as flooded battery, might be a suitable choice for your trolling motor and the cheapest option available. This battery has some drawbacks since it requires regular maintenance and has a relatively small life span, which is why we only recommend it if you are only angling for one season.

Sealed Lead-Acid (SLA) Absorbed Glass Mat (AGM) Battery

The trolling motor AGM battery is among the top choices for marine applications. This battery has a medium to long life span and requires very low maintenance. They are also much safer and resistant. Considering the longer life span of the AGM trolling motor battery and higher depth of discharge (DOD), this is a cheaper option in the long run and one of the best ones available.

SLA Gel Battery

SLA gel batteries can be really good for powering angling trolling motorboats since the technology is durable, reliable, and robust. The gel trolling motor battery life is also much longer than flooded when charged and discharged with the right voltage/amperage, but it can be somewhat delicate with these parameters. We recommend you only use a special charger if choosing a gel trolling motor battery.

Lithium-Ion Trolling Motor Battery

The lithium-ion trolling motor battery is another nice option for angling boats but also the most expensive technology. Choosing a lithium-ion trolling motor battery is mostly recommended for angling boats that, aside from powering a motor, require a power source for other high-consumption devices.

Top 10 Best Trolling Motor Battery Reviews

Choosing the right battery for your trolling motor is important. To help you pick among the best options available on the market, we compiled this trolling motor battery reviews section. You will find several quality models to choose from. Each one stands out considering certain specs, duration, quality, or price.

Buyer’s Guide – What to Consider When Buying a Trolling Motor Battery

Knowing what the best battery for a trolling motor is depends in particular on the technical specifications of the motor, the battery, and several other aspects. In this buyer’s guide, we will explain the most important aspects to consider when choosing the best trolling motor battery for your angling boat.

What Is the Best Capacity for You?

The capacity of the marine battery defines how much usage time you get from one charge. You might choose among three group sizes: low batteries with up to 40 Ah, medium batteries with up to 70 Ah, or high-capacity batteries that usually go up to 100 Ah and sometimes beyond that capacity. You will need to find out how much constant amperage is required by your trolling motor and estimate the number of hours you would be using it. That way, you will be able to find out how much capacity you will need for your trolling motor, plus other loads if needed.

The installed capacity will influence a trolling motor battery size and weight. It is important to pick the battery with the right capacity size, weight, and dimensions, especially if you have a small angling boat.

Which Is the Best Battery Type?

Choosing the proper battery technology will define the trolling motor battery life, required maintenance, maximum depth of discharge, amperage, and other aspects. Some batteries are designed with gel technology, but the best options available for marine applications are AGM trolling motor batteries.

What Is the Proper Budget for a Trolling Motor Battery?

Acquiring a low-, medium-, or high-end battery varies concerning your budget and the type of trolling motor installed at your angling boat. Some batteries have an extended life span and better specs, but they usually cost a little more. If you can spare the bucks, these might be better choices for your boat, especially with their longer life spans and extended warranties.

Voltage

Most trolling motors indeed require a 12V trolling motor battery, but some high-end models need a 24-volt trolling motor battery. If you do not find an adequate choice within the 24-volt range, you can just install two quality 12V marine batteries in series. This will give your motor enough power to properly function and even power other electronics onboard.

What Is the Temperature Needed to Install the Battery?

The capacity of trolling motor batteries is usually reduced by exposure to low-climate temperatures. Temperatures of -4ºF (-20ºC) might only get you 40–70% of the capacity, while to get 100% of the capacity, they should be exposed to temperatures of 77ºF (25ºC).

Climate temperature also affects the life expectancy of the battery. Some batteries last up to 10 years at 50ºF (10ºC), while they will only get up to 3 years at constant 113ºF (45ºC). We recommend you provide shelter and special temperature insulators for your batteries during winter and cold temperatures in general and do your best to keep the room temperature where the batteries are located as close to 25°C as possible.

Size and Weight

A trolling motor battery size and weight are two very important aspects to consider when choosing a battery. You should pick a model with the right size and weight, especially if it is for small boats like kayaks, canoes, and other compact angling boats.

Maintenance and Proper Usage

A trolling motor AGM, gel, or lithium battery requires close to no maintenance, but it is still important to take proper care of it, meaning that you should know how to charge trolling motor batteries at the right voltage and current. Discharging a battery only to 50% of its capacity and using a charger allowing you to set the parameters to those recommended by the manufacturer are enough to ensure a longer life span for your battery.

Life Span and Number of Cycles

The lifespan of a battery is defined by the number of cycles you can charge and discharge a battery at a certain DOD. The higher the DOD, the lower number of cycles your battery will last. You can always extend the life span by discharging it up to the 50% recommended DOD and learning how to charge trolling motor batteries with the right voltage and amps.

Operating Amperage

The operating amperage of a battery is defined by its C-Rate. Most marine batteries have C10 or C20 rates, meaning that their capacity can be steadily discharged in a 10- or 20-hour period with the max current being equal to the capacity of the battery between those hours. Some batteries provide higher currents, but regularly using this maximum current decreases the capacity of the battery in the long run.

Conclusion

Many trolling motor batteries can be perfectly suitable for your angling boat. If you pick among the available models in the trolling motor battery reviews section and use the buying guide to help you choose, you will get the perfect model suiting your trolling motorboat.

Properly choosing a battery considering its technology and type of applications are a vital part to get a battery that will last you for years. You should also take proper care of your battery by discharging it to its recommended DOD and charging it back up with the recommended parameters by the manufacturer. This practice will ensure a proper functioning and longer lifetime for your battery.
