Features to Consider When Buying Trolling Motor Batteries (Buyer’s Guide)

Each person has different preferences and needs regarding trolling motor batteries, such as fishing frequency, budget, and vessel size. You also need to familiarize yourself with some key features in finding the best trolling motor battery. Here are the features to take note of to make the buying process of trolling motor batteries easier.


Trolling motor batteries have a specific voltage to power up the motor. Most 12V trolling motor batteries can power 12V motors and electronics when on-board. However, a powerful 24V trolling motor may require two 12V batteries to ensure your vessel will get enough power.


Durable batteries are often built to last, so better keep an eye out for batteries with superior durability features. AGM batteries come with sealed casings, allowing them to withstand water leakages, damage, and vibration issues.

However, AGM batteries are more expensive than their wet cell counterparts. The added durability comes with a heftier price as it ensures a long run time. Nevertheless, the extra price will pay off over the years.


Wet cell batteries may require some minor maintenance by cleaning it as necessary, applying it with filtered water, and inspecting corrosions. Removing traces of corrosions is easy by just mixing baking soda and water.

Although this may be quite a hassle for some, wet cell batteries are ultimately affordable, so the need for infrequent maintenance is still worth the savings.

On the contrary, lithium-ion and AGM batteries require no maintenance, which means you don’t need to check the water level frequently or any signs of damage.


A trolling motor’s size and weight may affect its battery performance, so make sure you find one that isn’t too heavy for the boat. When a boat has reached its weight capacity, the battery will drain faster, so you better look for lightweight batteries when reaching maximum capacity.

Anglers who don’t put too much weight on their boat don’t need to worry about having heavier batteries. Batteries often weigh 20 to 50 pounds, but anything below 30lbs is ideal for kayaks. Ideally, anglers who have smaller vessels do not require a heavy battery.


Make it a habit to prioritize the battery size when choosing one that is suitable for your boat. Having limited space requires a battery that is compact enough to fit into the vessel. Meanwhile, large batteries are suitable for bigger boats. The heavier the boat, the more power it will drain every hour, so you need a large battery when you have a bigger watercraft.


A trolling motor battery’s lifespan depends on the battery type you will buy. Wet cell batteries often have the shortest lifespan with a maximum of two years with regular maintenance. Conversely, AGM batteries have a longer lifespan, averaging from three to five years, depending on its quality, while lithium-ion batteries can offer as much as ten years.


For those who regularly use their trolling motors, you need batteries with quicker charging time, so you have lesser waiting time. AGM batteries are ideal options when it comes to fast recharging times. They charge up to 98% with fuller and quicker recharge.

The battery charger is another consideration. Those with bulk charging offer better bursts of short charges, meaning they aren’t the best ones when fully recharging a battery. Instead, buy a voltage regulation charger as it offers full and fast charges.


Trolling motors are certainly versatile. Picking the right battery to keep your trolling motor turning can provide you a longer lifespan while having your money’s worth. Although there is a wide array of trolling motor batteries on local dealers and online markets, it can be overwhelming when choosing the perfect model. 

The Universal Power Group 12V 100Ah Battery takes the spot as the best trolling motor battery. It is a high-performing power unit designed and manufactured using the Absorbent Glass Mat (AGM) technology for a faster charging process. Plus, it doesn’t require regular maintenance, and you can also use the battery with lead-acid.

For those looking for a reliable trolling motor battery, the Universal Power Group 12V 100Ah Battery is certainly a great buy. With its AGM technology construction, you can guarantee that it will work impressively.

Several numbers of premium-quality trolling motor batteries are available on the market.

Each of these models ensures exceptional performance to allow you to enjoy hours of hassle-free fishing.

FAQs (Frequently Asked Questions)

Here are some common questions about trolling motor batteries to help you with your purchase decision.

How long can a trolling motor run on battery?

Running time depends on the battery’s ampere-hour (Ah), which is the amount consistently delivered by a battery per hour. The higher the Ah, the longer the battery will last. Trolling motor batteries often have Ah ratings that range from 25Ah up to 100Ah.

The ampere drawn from a battery depends on your trolling motor and water conditions. For example, a 100Ah can last up to four hours when the draw is 25Ah, but it could last over ten hours if the ampere draw is only 10Ah.

The Ah rating determines how long the battery can run the motor. For those who own a large motor and boat, you need at least 100Ah battery, while smaller boats can do well at 25-75Ah. However, you want at least a larger battery to achieve maximum running time for your motor.

What size should I get for my trolling motor battery?

A few factors influence the size of a trolling motor battery. When choosing a battery size, consider the following things: boat size, trolling motor power, and how often you go fishing. The size of your trolling motor and boat will depend on the required size for the battery. Large vessels and motor need a battery with a decent Ah to perform well without draining quickly.

Small boats with small batteries tend to have more flexibility since they are a great way to save money while getting a decent battery size that suits your needs. Although big batteries on small boats are not bad, they can provide longer run time for fishing.

How long can a trolling motor battery last?

The battery’s runtime usually depends on how it is well maintained. Often, wet cell batteries have a short lifespan for a maximum of two years, which you can only achieve if you will maintain it regularly by applying fluids and checking for corrosion.

On the contrary, AGM batteries have a longer life expectancy that ranges from two to four years depending on battery quality. They don’t require frequent maintenance, so you will likely obtain its maximum lifespan unless it acquires damage.

Meanwhile, lithium-ion batteries have the best lifespan, with an average of 10 years. Given its longevity, you get your money’s worth by investing in this battery type.
