Buying Guide: How to Choose the Best Trolling Motor Battery

It’s no secret that we all have varying preferences and needs when it comes to trolling motor batteries. Ranging from your fishing frequency and budget to the size of your vessel, there’s a wealth of factors that will determine the best fit for you. With that being said, we’ve rounded up a few buying tips to make the process of selecting the best trolling motor battery a breeze.

Voltage

Granted, most of the trolling motor batteries you’ll stumble upon are 12V. So, they’ll power on-board electronics and motors of the same voltage. But, if the motor is 24V, for instance, then you’ll need a couple of 12V batteries to guarantee sufficient power. You’ll typically have a 12V motor unless it’s high-end. So, most trolling motor batteries will pair well with your vessel.

Durability

It’s a no-brainer that durable batteries last longer. So, keep your eyes peeled for features that accentuate a battery’s durability. For instance, AGM batteries are fully sealed within their casing. In turn, this diminishes their susceptibility to leakages, damage, and problems stemming from shock or vibrations.

But, AGM batteries are pricier than the wet cell counterparts. Ultimately increased durability comes at a cost. However, shelling out extra bucks means a longer-lasting battery that ends up paying for itself years down the road.

Maintenance

Wet cell batteries demand a level of maintenance from time to time. It entails refilling them with filtered water, then looking out for signs of corrosion and cleaning as required. With the perfect ‘cocktail’ of baking soda and water, getting rid of corrosion is a breeze. Granted, this is more of a hassle than the battery’s worth.

But remember, wet cell batteries are pleasantly affordable. So, the need for minor maintenance may be worth it for those angling to save extra bucks. Contrarily, lithium-ion, and AGM batteries don’t need any form of maintenance.

Therefore, inspecting the battery’s water levels or interior for signs of damage is the least of your worries. While they’re pricier than the wet cell counterparts, they’re 100% maintenance-free.

Weight

Along with the size, the weight of the trolling motor battery affects its overall performance. So, ensure it’s not overly heavy for your vessel. Upon reaching your boat’s weight capacity, the battery will drain notably faster.

Therefore, opt for a lighter battery if you’re getting to the maximum capacity. Fortunately, a myriad of anglers doesn’t have much weight on-board, which means a heavier battery isn’t an issue. Typically, batteries weigh anywhere between 25lbs and 30lbs. Anything less than 30lbs is suitable for kayak users.

Keep in mind, if you’re using a smaller vessel, ensure the battery isn’t too bulky; otherwise, it could negatively impact its efficiency. If you have a high weight capacity on-board, then a heavier battery for enhanced performance is a better fit.

Moreover, if you require transporting the battery to and from the vessel with every use, then a more compact and lightweight option is better. But, if it’s permanently installed on the vessel, then the weight is a nonfactor because you don’t need to carry it around.

Lifespan

It varies greatly from one trolling motor battery to another. For instance, a wet cell battery has the shortest lifespan of up to 2 years with optimal maintenance. Contrarily, AGM batteries have a longer lifespan that stretches up to 5 to 6 years based on the quality. And the newer lithium-ion counterparts take the cake with up to a decade. Keep in mind that a longer lifespan comes at a steeper price.

Size

Always factor in a battery’s size before hastily purchasing it to confirm that it’s a great match with your vessel. For instance, is your boat roomy enough for bigger batteries? If it lacks the luxury of space, then ensure you select a compact trolling motor battery that can comfortably fit on-board.

If you have a larger boat, then a bigger battery will be perfect. A heavier vessel means more power is being drained per hour. Therefore, a larger battery is more ideal for bigger watercraft. You have free rein to go bigger with your trolling motor battery if there’s enough room.

It guarantees there’s a sufficient chance to consistently power the motor for extended periods. In turn, you can revel in your onboard adventures without worrying about the battery giving out after 1 or 2 hours.

Recharging

Think about how frequent you require recharging your battery. If you frequently use your trolling motor, then a fast-charging feature is a necessity as it ushers in more adventures and reduced waiting time. So, AGM batteries are your best bet. They charge up to 90% in under an hour, thus adding a layer of convenience.

Bottom Line

No one likes having to wrap up their onboard excursions as a result of a dead trolling motor battery. Fortunately, in today’s technological era, these batteries are better than ever, offering enhanced performance, little to no maintenance, and much more. So, order yours today!
