Some good deep cycle trolling motor batteries include Optima Blue Top and the Interstate DCM0035, according to Fishing Tips Depot. These batteries are spill-proof and feature vibration resistance.
The Optima Blue Top is a deep cycle battery specifically for tough marine applications. Optima is a market leader in battery design and construction and promises that its batteries have up to three times more charges than the batteries produced by its competitors.
The interstate DCM0035 battery is a good deep cycle battery with great performance and reliability. The battery has an extended life and optimal high-power density. Because interstate does not use spiral-wrapped technology, it may be more prone to damage by vibrations than the Optima Blue Top.
