Best Trolling Motor Batteries

Voltage - Think of voltage as how much power is inside the battery. 12V is a good trolling motor voltage, which is a good thing. Why? Because all of our top-rated trolling motor batteries are, in fact, 12V.

How to Choose the Best Trolling Motor Battery

Amperage - This is a little tricky. Think of amperage as how the power that is voltage comes out of the battery. The number we give you is amp hours. Basically, the more amps, the longer the battery will last.

Warranty - Ah, warranties. We like when they’re long. In fact, the longer, the better. It just shows that a company has faith in its product. Which most likely means it is actually a good product. And that makes us happy.
