What to Consider When Choosing a Battery for an Electric Trolling Motor

Dual Purpose Batteries

Dual purpose batteries gradually release a large percentage of their total capacity over a period of time. As its name suggests, this type of battery serves a dual purpose – starting and deep cycling. These can provide a consistent and steady electric power to your trolling motor, and at the same time, crank engines.

If you can only buy one battery for your entire boat – inboard or outboard motor and the trolling motor – a dual-purpose battery is the ideal choice. These batteries are designed to do everything and give a good (just good, not great) performance for deep cycling.

Deep Cycle Batteries

Deep cycle batteries release a large amount of their capacity over a long period. This type of battery lasts longer than dual purpose batteries when used on a trolling motor. However, even with a small deep cycle battery, you will still get a good performance.

Deep cycle batteries are the ideal choice if you’re looking for a battery just for your trolling motor.

Power System

The majority of trolling batteries are designed for 12V motors. So if you have a 24V trolling motor, you’ll need two batteries. Needless to say, it’s important to know and check your motor power system before buying any motor battery.

Amp Hours (Ah)

In a nutshell, the amp hours indicate how much electricity a battery can store. Deep cycle batteries are often rated in amp hours, but not all dual purpose batteries are rated. The rule of thumb is that small batteries will usually be 25 – 50Ah, while larger deep cycle batteries can reach 100Ah. For a trolling motor battery, the higher Ah means your battery can provide power for a longer period of time.

The design of the battery, the maintenance required (or lack of it), and its construction are other things you should look at when choosing the best battery for your electric trolling motor.

Next, we’ll take a closer look at the features of the batteries we’ve listed earlier.

FAQs About Trolling Motor Batteries

Q: How long will my battery last?

A: The service life of the battery greatly depends on how you use and maintain it. Generally speaking, trolling motor batteries can last anywhere between 2-6 years. Be sure to follow the user manual to ensure that you’re properly taking care of the batteries.

Q: Can I use any kind of battery for a trolling motor?

A: Generally speaking, if the battery you’re using gives out 12V of power (you may need more than one depending on your motor), you should be ok. However, you need to think about the deep cycle and dual purpose batteries we discussed earlier. If you are unsure, check the user manual for your trolling motor or consult a technician at a marine dealership.

Q: Do I really need a battery box/cover?

A: It is not 100% necessary, and if you don’t really have the budget for it, don’t sweat it! However, when you are able to get one, a battery cover is a pretty good investment since it will protect your battery from nicks, scrapes, and dents, not to mention getting wet from the rain and splashing water.

Q: Where is there more information on the wire sizes and lengths?

A: Depending on the voltage, draw, and distance, you’ll need specific wire measurements. You can consult an electrician in case you’re unsure of technical electrical circuits or if you are in the process of modifying your current setup. If you use a wire that is too small, you risk reducing the power of your trolling motor, causing it to drain your battery faster.
