Trolling Motor Maintenance Supplies
Here’s what you’ll need to maintain your trolling motor battery:
- Basic tools

- Voltmeter
- Electronic contact cleaner
- Heavy duty corrosion inhibitor
- NCP2 battery corrosion prohibitive
- Dielectric grease
How To Maintain Your Trolling Motor Battery
Here’s how to maintain your trolling motor battery, step by step:
Step 1: Disconnect each connector and brush away any corrosion
Step 2: Reconnect each connector
Although some people are against them, Bill likes wing nuts because they allow him to easily make changes on the water without the use of too many tools, although he does like to tighten them with pliers so they’re secure
Step 3: Spray the connections with corrosion resistance
Step 4: Check the voltage of each battery
Step 5: Check the voltage at the connector
You want to make sure there’s not a large drop in voltage from the battery to the connector, which would mean there’s a problem with your wiring.
Step 6: Check the voltage of the batteries while they’re charging
This will ensure your charger is actually charging the batteries.
Conclusion
By maintaining your trolling motor batteries every few months, you’ll be able to head off any problems at home before they happen on the water.

Just installed a new trolling motor and am thinking about new batteries. Thank you for the tips. I’m a relatively new to boating and would love to see more boating content from Salt Strong. Thanks for everything y’all do.
