How do I choose the right trolling motor battery for my boat?

Consider whether you need a deep-cycle battery for prolonged use, a starting battery for engine ignition, or a dual-purpose battery for both. Also, look for features like vibration resistance and durability if you’ll be using it in rough waters.
What is the difference between AGM and lithium-ion trolling motor batteries?
AGM batteries are typically more affordable, maintenance-free, and resistant to vibrations, making them great for moderate use. Lithium-ion batteries, while pricier, are lighter, have a longer lifespan, and recharge more quickly. If you prioritize performance and long-term savings, lithium-ion might be the better choice, but AGM batteries are reliable for most needs.
How long does a trolling motor battery last on a single charge?
The runtime of a trolling motor battery depends on its capacity (measured in amp-hours), the motor's power consumption, and how you're using the motor. For instance, a 100Ah battery might last 4-6 hours of continuous use at medium power, while running at lower speeds can extend this time significantly.
What maintenance is required for trolling motor batteries?
Most trolling motor batteries, especially AGM and lithium-ion types, are low-maintenance. However, keeping the battery clean, ensuring proper charging with the right charger, and storing it in a cool, dry place during the off-season can help extend its life. Regularly check for corrosion on terminals and ensure they're securely connected.
