A trolling motor is a small electric motor with a propeller. It is meant to be used on small boats, such as fishing boats and pontoon boats. Since a trolling motor generates less noise, it most likely won’t scare the fish away. And, of course, it lets you easily move around in the water without a sail or paddle.
Every trolling motor needs an excellent trolling battery for its power. A trolling motor battery will not only keep your trolling motor powered, but it could also supply power to some of your on-board electric accessories as well. Your battery choice is dependent on the type of boat, trolling motor, and accessories you have available.
There are two types of batteries for trolling motors: absorbed glass-mat (AGM) batteries and wet-cell lead-acid batteries. The lead-acid batteries are the traditional batteries used for trolling motors. Wet cell lead-acid batteries use water to saturate the lead plates, which increase the weight of them. You’ll be required to perform a lot more maintenance, such as checking the corrosion and fluid levels.
AGM batteries, on the other hand, are better for modern trolling motor marines. Since they don’t use acid fluid, AGM batteries do not require as much maintenance work. Terminal corrosion, for example, will never be an issue. You’ll never need to worry about malfunctions due to leaky acid or damage to the casing. As long as you don’t overcharge the AGM batteries, they will remain healthy and robust for a long time.
