Complete Buying Guide for Best Boat Trolling Motor Battery
Essential Factors We Consider
When picking a trolling motor battery, think about capacity (Ah) for runtime, voltage (12V, 24V, 36V) to match your motor, and battery type. AGM batteries are affordable and maintenance-free, while lithium LiFePO4 batteries are lighter, last longer, but cost more. Also, check weight for easy handling and safety features like low-temp protection for cold days on the water.
Budget Planning
Set a budget based on your fishing habits. For occasional use, a budget AGM battery works fine. If you fish often, investing in a lithium battery saves money long-term due to its lifespan. Remember to factor in a compatible charger, as lithium batteries often need specific ones.
Final Thoughts
There’s no one-size-fits-all. Match the battery to your boat size, motor power, and how long you stay out. Always prioritize safety and reliability over saving a few bucks upfront.
Frequently Asked Questions
Q: How long does a trolling motor battery last on a charge?
A: It depends on capacity and motor draw. A 100Ah battery with a 10-amp motor might last around 10 hours, but real use varies with speed and conditions. Lithium batteries often maintain voltage better, giving more consistent runtime.
Q: Can I use a car battery for my trolling motor?
A: It’s not recommended. Car batteries are for short bursts, while deep cycle batteries are made for sustained discharge. Using a car battery can damage it and leave you stranded.
Q: Do lithium batteries require special care?
A: They’re low-maintenance but need a lithium-compatible charger. Avoid extreme temperatures and monitor charge levels. Many come with BMS (Battery Management System) for automatic protection.
Q: What’s the difference between Group 24 and Group 31 batteries?
A: Group sizes refer to physical dimensions. Group 31 is larger, often holding more capacity, while Group 24 is compact. Choose based on your boat’s battery box space.
Q: How do I store my trolling motor battery off-season?
A: Keep it charged, especially for lead-acid types, and store in a cool, dry place. For lithium, a partial charge (around 50%) is ideal for long-term storage.
