Assessing Your Marine Battery for Trolling Motor Options
The right trolling motor battery for you depends on a variety of factors, like your budget and the type of boat you own.
- Capacity and voltage: A great first step to narrow down your choices is to check the manual of your trolling motor for battery specs. Generally speaking, the larger and heavier your boat, and the bigger your trolling motor, the more power you will need.
- Weight and size: You’ll want batteries that can fit in the spaces on your boat, and are light enough to move if needed.
- Lifespan and maintenance: Lithium batteries last a long time and require less maintenance, but are typically more expensive than alternatives. AGM batteries provide great performance with a lower price. Other types of batteries may be cheaper, but require more maintenance.
- Cost and value: A higher-quality battery may cost more upfront, but can offer more reliability and runtime, and require fewer replacements over time. The cheapest options don’t necessarily offer the greatest value overall.
- Charging time and convenience: Batteries with shorter charging times may get you out on the water faster, but the convenience may come at the cost of capacity. Find out whether the ones you’re considering are compatible with onboard chargers or solar panels if you want the option to extend your trips.
- Safety and environmental concerns: Robust safety features protect you from hazards like overheating and acid leaks. Environmentally friendly lithium-ion and AGM batteries reduce the risk of pollution and align with eco-conscious boating practices.
Choose Wisely to Meet Your Needs
Modern trolling motor batteries have come a long way over the last decade, both in terms of performance and longevity. Incorporating their benefits into your setup can help you catch more fish, and make your time on the water more carefree.
Given the wide variety of marine batteries now on the market, the task of narrowing down the options may seem overwhelming. From our perspective, you can’t go wrong with any of the recommendations on this list.
