Would you consider driving your car without a good battery? Didn’t think so. The same should be true for your boat.
That’s why you must find the right trolling motor battery. When you’re out on the water, you want confidence that you have a dependable battery for all your adventures.
Keep reading this guide to learn about the different trolling motor batteries available for you.
Types of Trolling Motor Batteries
When you begin your search, you will see that there are various trolling motor batteries types. However, before looking for any trolling motor battery, you must know the amount of power you require.
Identify the maximum, medium, and minimum speed currents. You also need to know the trolling motor thrust. Finally, make a note of the boat’s size and weight.
Once you know the specifics, you can start looking at different types of batteries.
Starter batteries discharge a large current for a short time. So, they shouldn’t have their charge regularly drop below 50% with consistent recharging.
Therefore, starter batteries don’t make for a good choice for your trolling motor.
Deep Cycle Batteries
Deep cycle batteries discharge small amounts of current over a long period. They are designed with trolling motors in mind.
Batteries with ‘Ah’ ratings can deep cycle. Therefore, you want to avoid batteries that only have a cold cranking amps (CCA) rating. Professionals use Peukert’s Law to know what Ah rating is suitable for each user.
There are two types of deep cycle batteries that make for the best trolling motor battery.
Lead Acid Wet Cell
Lead-acid wet cell batteries handle frequent draining and recharging. As a result, they are the most popular option for users looking for a small trolling motor battery. This is because they are affordable.
However, they are prone to vibration and spillage. They require extra maintenance and only last for 2-3 years.
Absorbed Glass Matt (AGM)
AGM batteries are completely sealed, so they last longer than lead-acid wet cell batteries. Their life span is usually 3-4 years. Unfortunately, they can be double the price of lead-acid wet cell batteries.
Absorbent gel batteries are also available. They use gel rather than glass to make the plates buckle resistance. It’s a good option for a boat that will experience a lot of vibrations. If not, the cost isn’t worth it.
What about a Lithium Trolling Motor Battery?
In recent years, lithium batteries have become more popular. They are lightweight and have much longer battery life. They can last up to 10 years!
Additionally, lithium batteries give full power regardless of the level of charge. This gives you more energy.
But, lithium batteries are significantly more expensive than other choices. They can be as much as 3-5 times the price. However, because they last so much longer, you may save money in the long run.
