Buyer’s Guide for Choosing the Best Trolling Motor Batteries – What to Consider 

It’s no secret that we all have varying needs and preferences for all sorts of appliances. And well, things are no different with trolling motor batteries either.

Ranging from your budget to your fishing frequency and boat’s size, a vast array of factors will define the best trolling motor battery for you. We’ll look at some of these factors in detail and offer buying tips in between to help make the entire buying process a breeze.


Before purchase, the battery’s size is one aspect you must factor in to ensure the unit ideally matches your boat. Ask yourself, does your vessel offer adequate room for bigger batteries? If not, you’ll want to consider compact trolling motor battery options that can fit aboard comfortably. 

In the same way, if your vessel is relatively large, then a more extensive battery could be ideal for you. In other terms, the larger your boat, the more power it’s likely to drain per hour, making larger batteries more suited to the task.

They assure a good chance of consistently delivering power to the motor over extended periods allowing you to revel in your boating expeditions without fretting about the battery running out too soon.


Buyer's Guide for Choosing the Best Trolling Motor Batteries

From time to time, wet cell batteries will require some degree of maintenance measures. You’ll need to clean, inspect any signs of corrosion and refill them using filtered water. In case you notice some corrosion, the perfect ‘cocktail’ of water and baking soda may come in handy to get rid of it. 

Nonetheless, this procedure seems more of a hassle than the unit’s worth, with wet-cell batteries being pleasantly inexpensive. But the minor maintenance could be worth it if you wish to save some bucks. 

On the contrary, AGM and lithium-ion counterparts don’t demand any maintenance. And hence, inspecting the battery’s interior for any damage signs and water levels is the least of your concerns. While they are 100% maintenance-free, these batteries come with higher price points than their wet-cell counterparts.

Durability and Lifespan    

Durable batteries last longer, with the same applying to trolling motor batteries as well. So, it’s vital to look for distinct features showcasing a battery’s longevity. Take AGM batteries as an example; they display tight sealing in their casing to help reduce their susceptibility to damage, leakages alongside other problems that may arise from vibrations or shock.

Such features justify the AGM batteries’ high price points. After all, like with other products, bolstered durability always comes at an additional cost. And even after shelling out a few more bucks, such batteries will end up paying for themselves in the long term.

The lifespan, however, varies significantly among different trolling motor batteries. For instance, wet cell batteries have the shortest lifespans lasting roughly two years with optimal care and maintenance. 

On the other hand, AGM counterparts have their lifespan stretching between 5 and 6 years depending on quality, while their advanced lithium-ion rivals win the prize with lifespans averaging a decade. Take into account that the longer the lifespan, the more expensive the battery. 


Along with the trolling battery’s size, how much it weighs also influences its performance. See that the battery you pick is not overly hefty for your boat and should match its weight capacity. Anything contrary to that will have the battery draining power notably quicker.

Therefore, if you are approaching the vessel’s utmost capacity, it’s wise to opt for a lighter option. Fortunately, most anglers don’t carry too much weight aboard, which translates to a heftier battery not being an issue, given typical trolling motor batteries weigh roughly 25 lbs. to 30 lbs.

Anglers looking for something to suit their kayaks should consider batteries weighing less than 30 lbs. With such small watercraft, you’d want to ensure the battery you pick isn’t too bulky, which could negatively affect the unit’s efficiency. But if your vessel vaunts a high weight capacity, go for a heavier trolling motor battery.

At the same time, assuming you have to transport the battery to and from your craft each time you go for your boating adventures, you should opt for a more lightweight and compact option. But if you need a trolling motor battery to install on your boat permanently, the weight is thus a nonfactor.

Voltage and Recharging

Generally, most trolling motor batteries you’ll come across feature a voltage of 12V and will therefore power onboard motors and electronics that demand the same voltage.

However, some vessels employ high-end engines of 24V. In such a case, you’ll have to invest in a couple of 12V trolling motor batteries to attain adequate power but since most motors are 12V, expect most batteries to pair perfectly with your boat.

Also, consider how regularly you’ll need to recharge your motor battery. If you intend to have your trolling motor running often, it would be wise for you to pick a trolling motor battery that incorporates a fast-charging feature for reduced waiting periods and more adventures.

AGM batteries are a steal for you if that’s what you’re looking for. Typically, they use less than one hour to recharge up to 90%, significantly enhancing convenience.

Construction and Design

Best Trolling Motor Batteries Construction and Design

Fortunately, most modern lithium-ion and AGM trolling motor batteries feature sturdy constructions and designs that prevent leakage. They employ hard-shell plastic to house the inside contents and keep them vibration-free while bolstering their durability.

Unlike the traditional wet-cell counterparts, modern trolling motor batteries are maintenance-free, meaning they can operate for years without demanding any servicing. As a result, they are relatively costlier than wet-cell units. However, in the long-term, you’ll understand the justification behind their somewhat higher price points.

Frequently Asked Questions

Question: Can I Employ a Car Battery to Power My Boat Trolling Motor?

Answer: No, you cannot use car batteries for a trolling motor. And this is because of the following three reasons. Firstly, a car battery may feed your trolling motor with excessive current, which could in turn damage the engine itself alongside other electronic components on board. 
Secondly, a car battery’s design produces high current energy bursts and stores relatively low amounts of power. And with trolling motors demanding lots of power, car batteries lose the case to deep cycle options.
Finally, it’s not advisable to drain a car battery to low levels, something a trolling motor is likely to do. If it completely dies, its cells incur damages when recharging, which reduces the battery’s lifespan and performance.

Question: How Frequent Should I Charge the Trolling Motor Battery?

Answer: It would be best if you charged your trolling motor battery after every use. And it is advisable to not let the battery drain entirely to no charge as this can badly affect its performance. We’d also advise you to charge your trolling motor battery before storage fully.
Moreover, as long as your trolling motor battery remains connected to the main motor, expect it to charge provided the engine is running. Also, if you use the trolling motor more often than the main engine, your battery will remain charged after every use.

Question: How Can I Charge My Trolling Motor Battery While on Water?

Answer: It is possible to charge your trolling motor battery as you go around your on-water adventures, and there are three distinct ways to do that. These include:
Portable Charger: A light portable charger is an excellent starting point. It’s effortless to carry on your boat and generates decent charging speed for your trolling motor battery. 
Even more impressive, some of these chargers incorporate innovative technology that prevents your trolling motor battery from overcharging through automatic disconnection.
Solar Charger: You can also generate clean and pure energy from the sun using a Solar Charger. You could even make your own as long as you have an admirable quality solar panel, which you’ll fit on your boat’s roof. 
Additionally, you need a boost converter that will help turn the low-voltage solar energy to the 12V power your trolling motor battery requires for charging. However, a DIY solar charger is a pretty costly affair, and therefore, we’d advise you to purchase one.
Onboard Charger: Onboard trolling motor battery chargers come in distinct variations, including Digital, DC alternator, and Precision. They are all efficient and will recharge your battery within no time. For that reason, they tend to be costlier than their portable counterparts.

Question: Why Are Deep Cycle Batteries Preferred for Running Trolling Motors?

Answer: Unlike other batteries, deep cycle batteries are specifically designed to emit power over an extended period gradually.
For that reason, they are ideal for trolling motors since they allow boaters and anglers to go about their on-water excursions for long hours. In other words, they don’t exhaust their stored power too fast like in regular batteries and will therefore not leave you stranded on the water.  

Wrapping Up

By now, it’s a no-brainer that the battery cuts it among the essential components of a trolling motor. And I’m confident that nobody would like to forcefully wrap up an onboard outing because of a dead trolling motor battery. To avoid such inconveniences, you must get your vessel one of the best trolling motor batteries in the market.

Fortunately, and thanks to technological advancements, trolling motor batteries are now better than ever before. They assure enhanced performance and efficiency, minimal to zero maintenance, reliability, and much more.

All our options above qualify as excellent starting points. But if you’re still unsure which trolling motor battery to pick, consider the Universal Power Group Deep Cycle 12V Battery. It’s highly versatile, maintenance-free, and delivers exceptional performance.
