How To Get the Most Out of Your 36V Trolling Motor Battery

Investing in a 36V trolling motor battery is a wise choice for any serious boater. It provides more power, speed, and durability than other types to give you a great day on the water. Whether you’re fishing for a big catch or leisurely cruising, a trolling motor battery will help you navigate the waters with ease.

It's important to understand how to get the most out of your 36V trolling motor battery. We'll share the top tips and tricks to help you maximize your investment and enjoy an unforgettable time on the water.

1. Charge Your Battery the Night Before

Ensure the battery is ready to go by charging it the night before heading out on your adventure. This will allow it to reach maximum capacity and power potential. If you're heading out for multiple days, bring a portable battery charger in case you need to juice up on the water.

One of the most obvious benefits of charging your device the night before is that it will be ready when it’s time to go. Whether you're heading out for a short ride or a long adventure, you can feel confident that your device will have enough battery life to get you through the trip.

2. Keep the Battery Cool

Heat can significantly impact the life of your trolling motor battery. Store it in a cool and dry location, away from direct sunlight. While on the water, avoid exposing the battery to extreme heat or placing it near the trolling motor, which generates heat. This approach can maximize your battery's lifespan.

Charging your battery in extreme temperatures can negatively affect its performance and lifespan. The ideal temperature range to charge your cell is between 50 and 86 degrees Fahrenheit. If the temperature is higher, wait until the weather cools down. If the temperature falls below freezing, it is best to avoid charging the battery outdoors.

3. Use the Correct Type of Battery

Ensure you’re using the correct battery type for your trolling motor. Not all batteries are created equal; we recommend a deep-cycle marine battery for a trolling motor with high power requirements. This battery type is ideal for marine use, giving you optimal performance on the water.

Consider your options when shopping for a boat motor battery. Common types include lead-acid, AGM, and lithium-ion batteries. Lead-acid batteries are the most affordable but require the most maintenance; you must top them off with distilled water to keep them stable. AGM batteries are more expensive but require less maintenance. Lithium-ion batteries are the most expensive but have the longest lifespan and require little maintenance.

4. Monitor Your Battery Level

Keep an eye on your battery’s power level to avoid getting stranded on the water. Most trolling motor batteries come with a battery-level indicator, and it's good practice to check it periodically throughout your trip. If the level is low, decrease your trolling motor's speed or switch to a propeller with less resistance.

Your boat's battery system constantly charges and discharges, and its level may fluctuate frequently. Therefore, you must understand the battery's life cycle to avoid overcharging or discharging it completely. As a boat owner, you must invest in a reliable battery monitoring system to receive real-time data on the battery's performance. This setup will help you keep track of the battery's level, calculate the remaining charge, and alert you of any issues.

5. Perform Regular Maintenance

Regular maintenance can prolong a trolling motor battery’s life. This includes cleaning the terminals, inspecting the wiring, and checking for any cracks or damage to the battery case. Taking care of your battery will ensure its performance and longevity. A well-maintained cell can power your vessel for a long time, and you can enjoy your time out on the water without disruption.

One of the most crucial parts of maintenance is monitoring the electrolyte levels. If the level is too low, it can damage the interior plates of the battery, making it unable to hold a charge. Regularly check the battery's electrolyte levels and top them off with distilled water at least once a month.

6. Ensure the Battery’s Voltage Supports Your Boat

Voltage measures electrical potential energy and represents the force that drives a current through a circuit. It creates the pressure that pushes electrons along the conductor. The higher a battery’s voltage, the more potential energy it can supply to the system. For example, a 36-volt lithium trolling motor battery will give your boat a longer runtime than a 24V.

Boats require a significant amount of energy to operate. They use electricity to run the engine and power the lights, radio, and other accessories. Therefore, you need a battery that supports your watercraft’s functions. Many boats have 12-volt batteries, which provide enough energy to power most components. However, large boats with many features may require 24-volt or 36-volt systems.

7. Keep the Cell Clean

Marine batteries play a crucial role in powering the various electrical appliances on your boat. They keep the lights, radio, and navigation systems operational, making it essential to keep your marine battery in good condition. Regular maintenance helps you prevent damage that can decrease the battery's lifespan or cause sudden complications.

A clean battery is a healthy battery. Dirt and debris can weaken the terminals and lead to a short circuit. Keep the battery clean and remove any buildup immediately. Use baking soda and a soft-bristle brush to clean the battery and terminals, then rinse with water to remove acidic crystals that can damage the cell.

Enjoy Your Boating Experience to the Max

Investing in a 36V trolling motor battery is a significant step toward a successful fishing or boating experience. Lithium-ion batteries are the best choice for energy density and charge efficiency, but your choice ultimately depends on your needs. By following these tips and tricks, you can ensure your trolling motor battery lasts a long time, performs well, and helps you navigate the water with ease.

Remember to keep your battery fully charged, cool, and clean! Enjoy a fantastic time on the water by getting the most out of your 36V trolling motor battery!
