However, something like a state of the art Minn Kota trolling motor battery will work with any Minn Kota model. Minn Kota are also known to make the best trolling motor battery, listed below.
While we will be providing trolling motor battery reviews all numerous different models, there will be some tips and tricks that you should look out for when getting yourself the best trolling motor battery possible. They are not incredibly difficult to grasp and therefore we will not spend a long time explaining them in this article.
What is a trolling motor?
For anyone who is new to fishing or trolling motors in general and may not be fully aware of what a trolling motor is, they are a self-contained unit or device that comes with an electric motor, propeller and controls for the owner to use. The controls allow the direction for the trolling motor to be established, as well as the speed at which the motor will run.
Most of the time, trolling motors are situated at the front of the boat and will be pulled out of the water using a hinge mechanism to prevent drag or damage to the trolling motor while the main boat motor is being used.
The idea for trolling motors was originally conceived in 1895 in an article from the Scientific America which was titled “A Portable Electric Propeller for Boats”.
It was not until 1934, when a man from Fargo, North Dakota named O.G. Schmidt took a starting motor from a Ford Model A and combined it with a flexible shaft and propeller. O.G. Schmidt named the company “Minn Kota” due to how his company was to the North Dakota/Minnesota border. Some of the best trolling motor batteries are found in conjunction with the Minn Kota trolling motors.
Trolling motors are designed specifically to take advantage of the wide range of deep cycle batteries in the 12-volt capacity. The motors themselves are designed in a 12, 24 or 36-volt capacity. To prevent overheating, the water tight compartment that the motor sits in, is submerged in water. This keeps the heat down without any additional parts or components needed. A cheap trolling motor battery will almost always work in this case, as trolling motors do not require a lot of power to begin with.
Things look to look out for reading through trolling motor battery reviews
The battery you put in your trolling motor is critical part in getting the most out of your new or old trolling motor. Not buying the proper battery can result in the wrong amount of power or current being supplied to your trolling motor.
Keep in mind, that batteries for automobiles, namely cars or trucks – should not be used for trolling motors for sale. This is an incredibly important point to remember as deep cycle marine batteries (the ones you should be using) are meant to be used for long periods of time and ran down to a state of discharge, whereas automobile batteries are only meant to be used occasionally to supply excess amounts of power to help a car or truck engine fire up.
Pay attention to amp hour rating
This an important testing metric that all batteries are tested with. An amp hour is how much electric current a battery can supply for a certain amount of time.
For all trolling motors, we strongly recommend that you get a minimum of 110 Amp hour rating. This is the Amp hour rating recommended by all big trolling motor manufacturers.
Reserve capacity when looking through the potential trolling motor battery life
The reserve capacity testing metric may be just as important as the Amp hour in terms of gauging what kind of performance you may be able to get form any specific battery with your trolling motor.
The recommended minimum is 180 minutes reserve capacity. This is what you should look for if on the battery’s listing you cannot find Amp hours.
Once you’ve acquired your new battery – take care of it!
Taking care of a trolling motor battery is extremely easy and does not require much. The main point regarding physical maintenance is to always make sure that you properly wipe down the outside of the battery at least once a month to prevent corrosion.
Since you will be buying a deep cycle marine battery, make sure that you always recharge the battery within 24 hours of using it. The sooner the better. There are plenty of battery chargers out there that will make sure you do not over charge the battery, as this can lead to problems as well.
