Types of Batteries

Trolling motors come in different sizes and specifications. In the fishing world, Marine Deep Cycle Batteries are totally constructed with trolling motors, has a slow release of power, and the capacity to handle frequent recharging which makes it an ideal battery for all of us.

Below are the best deep cycle batteries that would work for your trolling motors with their benefits from each type.

AGM Battery (Absorbed Glass Mat)

The quality of the battery extends to their sealed plates which makes it highly resistant to vibration and corrosion. The battery cells are protected with its ultra-pure lead-calcium alloy plates. 

Its terminals are made from copper-silver alloy. AGM battery has a low self-discharging rate of approximately 3% of its charge in a month. 

The electrolyte is greatly absorbed which makes it more flexible. It lasts for more than 4 or more years which made it more expensive.

Lead Acid Wet Cell Battery

This battery uses lead plates and a combination of sulfuric acid and distilled water. It needs to recharge the battery and fill up the water when the water solution gets drained. This battery is affordable because it only has a short lifespan that would only last for 3-4 years and requires frequent maintenance.

Lithium Batteries

These batteries come with very lightweight materials and an affordable one. Your motor will run at an average speed level until the power runs out so there is no need to decrease the voltage over time and have a higher voltage output which makes its recharging time less than other batteries. The battery will give you a signal before they go dead. It contains the best deep cycle.

Gel Cell Batteries

These batteries are considered to be the best option. You need not charge it for a very long time, they never spill and can be mounted in any position. It lasts up to 20 years because you can attach them to a solar system to use stand-alone power storage.

However, they are low maintenance and can only recharge with an engineer alternator or a normal battery charger. Make sure your charger has been approved before using it to your Gel Cell Batteries.

What You Need to Know Before Buying Your Trolling Motor Battery

Amperage Hour Rating

This will give you information about your battery status before you recharge it again. It requires you to charge and provide the exact amperage hour of the battery for your trolling motor.

Marine Cranking Amperage

It indicates the amperes a battery can support and provide for 30 seconds at a temperature of 32˚F until its battery voltage falls to 1.20 volts. The higher temperature, the less voltage it could release over time. However, you don’t need to overbuy this kind of battery that you may never need to use.

The Weight and Size of your Boat

If you have a heavier boat, you need a more powerful battery. If you have a smaller one, you can choose a compact and mobile sized battery that would not weigh you down. However, you can opt for lightweight batteries to keep you moving.


The best pounds for your trolling motor should have at least 5 pounds of thrust for every 100 pounds of weight to accelerate your boat forward. Your battery should provide the power needed to achieve your thrust requirements.

Weather and Fishing Conditions

Opt for a battery that has a high amp hour rating whether you are in a low water fishing or deep water fishing in any weather and fishing conditions.
