Different Types of Trolling Motor Batteries

Just like the trolling motors, the trolling motor batteries are available in different shapes and sizes. Some of the common types of trolling motor batteries are explained below –

1. Lithium-Ion Batteries

Lithium-Ion Batteries are widely used in smartphones, laptops and other smart devices around the world as they do not take hours to get fully charged. These are powerful batteries and they can last really long if they don’t get overheated every now and then. However, it is a fact that these Lithium-Ion Batteries are relatively new in the trolling motor segment but they have already managed to carve out a niche for themselves among veteran kayakers.

The biggest benefit of using Lithium-Ion trolling motor Batteries is that they don’t weigh that much. So, carrying them around would not be such a big issue. However, Lithium-Ion trolling motor Batteries are a bit expensive but given their innumerable benefits, you can easily ignore the price tag.

Lithium-Ion trolling motor Batteries are used widely by anglers as they take less time to get fully charged and that means, anglers can concentrate more on catching fish rather than wasting time on charging their batteries.

2. AGM Batteries

AGM batteries are amazing. If you purchase an AMG Battery, you would not have to worry about sulfuric acid leakage at all. It has a unique construction that allows it to contain the harmful gases from coming out; so that means, you would not have to worry about investing in a ventilated case anymore.  

The full form of AMG is – Absorbed Glass Mat and they sport a conspicuous fiberglass construction. Since they come in an enclosed box, you can easily change their position. Since they take less space on kayaks, they are getting increasingly popular among kayakers.

Unlike wet cell batteries that take really long to get fully charged, AGM batteries do not take that much time to get fully charged and the top of that, they are extremely lightweight. These AGM batteries are ideal for kayaks and boats as they are extremely powerful and lightweight. 

The biggest advantage of AGM batteries is that you would have to spend a dime for maintenance. You can even use them as deep cycle batteries for trolling motors as they offer a superior level of service and can be used to charge and recharge batteries multiple times.

Here are some other advantages of using AGM batteries –

  • They can withstand vibration and their performance never gets adversely affected by vibration.
  • These batteries can perform perfectly in cold weather.

However, the performance level of these AMG batteries takes a nosedive in warm weather. Moreover, there is always a possibility of overcharging it. So, you have to be really careful about that.

3. Wet-Cell Batteries

If you don’t have that much budget to purchase an AGM battery, you can always settle for a Wet-Cell battery. It is probably one of the most affordable options available for trolling motors. Wet-Cell batteries contain liquid acid and which is why sometimes, they are referred to as flooded cell batteries. These batteries are chiefly used in cars as they are designed to withstand frequent draining and charging.

However, of late, they are getting adopted by trolling motors as frequent charging and recharging are also a part of its eco-system. Also, they don’t get overcharged that easily which is a common problem with other types of trolling motor batteries.

However, there are some serious drawbacks of wet-cell batteries. These wet-cell batteries need more maintenance and you might have to add distilled water every now and then. Another serious drawback of wet-cell battery is that it is not sealed properly and that means, the acid may start leaking from it. These batteries are also extremely susceptible to corrosion and this can have a serious impact on its longevity.  These batteries can’t deal with vibrations properly. Vibration can cause sulfuric acid leakage and that can cause significant damage to your boat. Moreover, you will also have to purchase a well-ventilated compartment contain the hydrogen gas that might get released by the battery. This is the reason why so many people these days are opting for AGM batteries.

Trolling Motor Battery FAQ

How Long Do Trolling Motor Batteries Last On Each Charge?

Well, it depends on the type of trolling motor battery you have. How long your trolling motor battery will last on a single charge is also dependent on the type of trolling motor that you have installed on your boat. The speed of the boat and the load of the boat can also have a crucial role in this matter.

At Kayak Manual, we think, you need to check the amp draw of the motor first. All you have to do is to divide the battery’s AMP hours by the trolling motor’s AMPs and you will get the number. For example, if the AMP hours of the trolling motor battery is 200 and the motor’s AMPs is 40, it means your battery will last 5 hours approximately.

How Should I Store The Trolling Motor Battery?
