Trolling motor battery buying guide

If you want to land the best trolling motor battery, you should consider a few things before selecting. In this guide, we’re going to look at some of the vital things to consider.

Sealed AGM or wet cell lead-acid battery?

Lead-acid batteries are the most common batteries on the market. These batteries utilize an electrolyte to flood the lead plates and that’s why they are usually heavy. Besides, lead-acid batteries need regular maintenance as the user has to inspect the fluid levels and monitor corrosion. One of the issues associated with lead-acid batteries is a vibration which reduces the battery’s overall lifespan.

This is not the same case with sealed AGM batteries. These batteries are maintenance-free and very durable. Also, most are vibration resistance, meaning the battery will last longer.

Deep cycle battery or starting a battery or dual-purpose battery

Trolling motors require a firm and consistent source of power. As a result, you will have to utilize a reliable battery such as a deep cycle battery or dual-purpose battery. This is because unlike the starting battery, these two batteries discharge a large percentage of their total capacity over time. On the other hand, a starting battery discharges a large amount of power at once to crank and start the engine. Because of this, you can’t only have a starting battery inside your boat to power your trolling motor, but you will need a deep cycle or dual-purpose battery.

Deep cycle batteries are great at discharging a great capacity over a long period and last longer. While the dual-purpose battery is created to crank the engine and deliver a consistent source of electrical power for trolling motors. So, the dual-purpose battery serves both the functions of a starting and deep cycle batteries. And by reviewing this best trolling motor battery, you might now have the idea which one to choose.


When selecting a trolling motor battery, you also need to look at the voltage. Getting a battery with a good voltage, such as 12-volt, is important. In some cases, some batteries have 24-volts or 36-volts, but these are best suited for very large boats. For small and medium-sized boats, the best batteries to select should have 12-volts.

Reserve capacity

If you intend to spend a lot of time in the water, you need to consider the duration of your battery. You don’t want to be stranded in the middle of a lake or ocean at night. Therefore, you need to look at the reserve capacity that the battery has. This is normally measured in amps per hour. Select a battery with at least 100-amp hours. This is enough time and it will allow you to accomplish many things.


Don’t just go for any brand. Ensure that you pick your trolling battery from some of the most reputable brands on the market. If you select a battery from an unknown brand, then you don’t know what to expect from it. Some parts could be unreliable or they may not offer support if you have a problem. Some of the most popular battery brands include Optima, Vmax, Universal Power Group, Mighty Max, Odyssey, and Interstate batteries.


Apart from selecting your trolling motor from a reliable brand, another factor to consider is the price of the battery. Some battery models are more costly than others. Always check out the features and performance of batteries before looking at the price. However, the top on performance of the best trolling motor battery is more costly than the least-performing ones.


Last but not least, you need to look at the warranty. Not all manufacturers offer good warranties. Some provide a 10-year warranty, others a 5-year warranty, and even some a 1 or 2-year warranty. The best brands offer the longest warranties, with some even offering a lifetime warranty. A good warranty adds confidence in the product as you’re sure that you’re protected.

Besides the warranty, you should also go through reviews and confirm whether the brand offers support or if the warranty is just another selling point for the brand. This will help you make your final judgment before buying the best trolling motor batteries.


Buying the right and the best trolling motor battery for your boat is very important. This is because it will determine how fast your boat can go and how long you will last in the water. Don’t purchase a battery because it is cheap but buy because it has the features that you want for your trolling motor. Compare different batteries from different brands and choose the one that best fits your boat size and the tasks that you want it to perform. Just know that there is no perfect battery, and you must decide between deep-cycle and dual-purpose batteries.

With our detailed review of the best trolling motor batteries, you can now pick a battery with the desired features and is within your budget.


What size of battery should I select for my trolling motor?

The trolling motor on your boat determines what battery size to select. Therefore, you need to know what group-size battery is ideal for your boat. Picking the wrong battery size might leave you in the middle of the water when your battery power depletes. For a small boat, a Group 24 battery that delivers up to 85-amps per hour at 12V is great. A group 27 battery that delivers up to 110-amps per hour at 12V is ideal for a normal boat. And for a larger boat, a group of 31 batteries that delivers up to 125-amps per hour at 12V will be perfect.

What duration does the AGM battery perform to its full capacity?

The duration the AGM battery lasts varies from one battery brand to another. Some batteries last up to 10 years, while others have a short lifespan of 2 to 3 years. Another key factor determining how long a battery lasts is its charger. A quality and recommended battery charger will ensure your battery doesn’t spoil quickly.

Is picking the right battery charger for my battery important?

Yes, it is. This is because different trolling battery manufacturers recommend different types of chargers. Apart from selecting an ideal charger, you also need to select a charger with the right amperage and it should be compatible with your AGM battery. However, picking a battery charger that is recommended by the manufacturer will help extend the life of your battery.

Should I choose a lightweight or heavy-trolling motor battery?

This depends on what you intend to do with the battery. A heavy battery will be a good choice if you want a powerful battery that will run for longer and last longer. Most heavy trolling batteries have more lead in their core, making them heavy, powerful, and with longer run time.

Why are deep-cycle batteries great for trolling motors?

This is because trolling batteries are designed to discharge power over a long period of time. As a result, they are great for trolling motors as the boat or Kayak may be out there for 7 hours or even more. For this to take place, you will need a powerful battery that can run for longer hours. A conventional battery will deplete power quietly, while a deep cycle battery will last for a longer period.
