What Are The Best Batteries For Trolling Motors?

There are a few factors to take into account while choosing trolling motor batteries: Type, size, amperage-hour rating, and price of the battery.

Lead Acid Wet-Cell 

The most popular deep cycle batteries for trolling motors are still lead acid batteries.

They are the least expensive alternative and can withstand the repeated draining and recharging of trolling motor operation.

Lead acid batteries typically last between two and three years, depending on quality.

Lead acid batteries have a few drawbacks, including the need for periodic maintenance, susceptibility to vibration, and leakage.

AGM Batteries 

AGM (Absorbed Glass Mat) Batteries are sealed lead acid batteries that generally last longer on a charge and have a longer lifespan.

AGM deep cycle batteries have a longer lifespan than conventional deep cycle batteries, which can last up to three or four years.

They are more costly but provide better performance and lifespan on the water. AGMs also have the advantage of being completely maintenance-free.

Lithium Batteries

There are several reasons why lithium batteries are gaining vogue.

Lithium batteries offer an average weight decrease of 70% over conventional batteries, making them ideal for smaller boats and boats where weight might be a significant consideration.

While lead acid wet-cell and AGM batteries typically have a life expectancy of 2-4 years, lithium batteries may last up to 10 years.
