Best Trolling Motor Battery: Is It Easy to Choose?

Batteries have been around since the early times, and in the recent decades, have allowed smaller mechanical or electronic components to operate without having to be plugged to an AC Power Source and be portable in the process. This is the exact same principle with ships and smaller boats, where voyage in the open seas and in bodies of water is made possible through a battery-powered motor, otherwise known as the trolling motor battery. Having said that, one has to make proper deliberations with choosing the best trolling motor battery to have the smoothest sailing experience possible.


How To Choose The Best Trolling Motor Battery

Knowing how to choose the best trolling motor battery is just as important as choosing other materials used in fishing. The reason for this is simply because the quality of your trolling motor battery could either make or break your fishing experience. Having said that, here are some of the things that you have to keep in mind whenever you go out choosing a trolling motor battery for the boat you’d be using when fishing:

1. Determine Its Battery Life

Determine its Battery Life

The longer the life of the Trolling Motor Battery is, then the better it is for you. This is for a rather obvious reason, and it’s that it would be an absolutely dreadful experience to have your motor dying out while you’re in the middle of the sea.

This would leave you floating and possibly stranded in the ocean or river for several hours, should it happen, which could expose you to the dangers of the seas. Most of the batteries available for trolling motors are of the lead acid variety, which is the same one used in cars.

In looking for a battery for trolling motors, look for one with a running time of at least 4 to 9 hours, and one which does not take a long time to charge.

2. Pick One With A Solid Design

Lead Acid, while touted as a highly effective substance for use in batteries, is one which is dangerous, given its low pH, or high acidity level. Exposure to lead acid could result to irritation and burns on the skin, as with lead having long-term cognitive effects brought about by its exposure. Having said that, it’s important that the trolling motor battery you decide to purchase is spill-proof in nature, given that rough seas could cause violent rocking on the boat might end up shaking the battery as well.

Pick one with a Solid Design

Another advantage of having a solid, waterproof design for your battery is that it could be placed virtually anywhere on the boat, without any risk, and one would not have to bother taking steps to “waterproof” the battery. While solid designs would usually mean a heavier weight, this would still be beneficial, nevertheless.

3. Always Remember To Check The Boat’s Weight

Check the Boat’s Weight

When it comes to choosing the best trolling motor battery for your boat for fishing use, it is of utmost importance for one to check and give due consideration to the weight of the boat first. The reason for this is that not all batteries, as long-lasting as they can be, are able to effectively provide the thrust that is needed for your boat to get going.

The same battery may bring a heavy boat longer to the desired destination longer than a boat which is much lighter.

4. Never Choose The SLI-Type Batteries

It was previously mentioned that batteries of cars are made of the same materials as the one for trolling motor batteries, specifically the presence of lead acid. It is equally important, however, for you to keep in mind that these batteries are especially designed solely for car uses. Cars are not as exposed to water as boats, and this alone makes a huge difference.

While SLI-Type Batteries would work for a while, chances are, these would die out much much quicker, as they are not made to power up trolling motors. Moreover, using these could end up damaging both the trolling motor and the battery itself in the long run. Pick only the most robust, and most suitable for activities such as fishing.

5. While Not Necessary, Extraneous Features Can Be Beneficial

Who says trolling motor batteries can’t be adorned with other accessories? There actually are a lot of motor batteries out in the market nowadays that not only provide power for the trolling motor, but allow you to charge other materials from the power of the motor battery as well. This includes cell phones and other communication devices like walkie-talkies and radio-frequency communicators, extra lights, and the like.

solar energy

While solar energy could be good for these materials, chances are, it would be tedious and expensive to have a panel installed in the boat, and not all the time are you assured that these essential devices would be charged fully before setting sail. A great alternative to solar panels would be “smart batteries”, which help to not just provide power to the trolling motor, but to other devices that you may bring along while fishing as well. These “smart batteries” are equipped with the necessary charging docks and USB Ports to allow charging to ensue.
