Trolling motors require a special kind of marine battery that’s quite different from a standard car battery. In fact, if you try to use a car battery in a trolling boat motor, you can end up accidentally damaging both the battery and the motor. That’s something you want to avoid!
What’s the difference between a trolling motor and car battery?
A trolling motor battery is a deep cycle battery. A car battery is short cycle. Car batteries can’t be recharged and drained often or they will die. The best trolling motor batteries are designed specifically to do this, as that’s what will happen when you’re fishing. Using the wrong battery in your trolling motor could cause it to overheat, burst, bulge, or break.
Batteries made specifically for trolling motors are usually very high capacity can handle the harsh conditions and the frequent charging and draining that a trolling motor battery can handle. If you want to make sure yours really lasts a long time, you’ll want to get one of the best trolling motor batteries available. We’ll discuss those further here.
One thing you want to be sure of is that you get a marine battery made for trolling motors. You could use a basic boat battery, but it’s not ideal.
A battery made for trolling motors will be able to withstand heavier wear and tear and will let you recharge less often while fishing more.
How to pick the best trolling motor battery
There are a number of factors to look into when choosing which unit to buy. Brand and price are definitely two of the main factors here. It may be true that you get what you pay for, but it’s also true that there are affordable trolling motor batteries for the money in many areas of the market.
The ideal model will be a sturdy deep cycle battery that is very high quality. Like we said above, this is very different from a short cycle battery for cars. You also need to look into how much your boat weighs, how much torque the motor has, and what type of fishing you’re going to be doing.
