Proper battery care and maintenance

Optimize your Mercury Precision battery’s performance

Proper battery care and maintenance are critical to ensuring uninterrupted time on the water for you, your friends, and family. Regardless of your boat or engine type, a dead battery will leave you stranded. Take proactive steps and make proper battery care and maintenance a priority.


To optimize your Mercury Precision battery’s performance, here are some quick tips to consider:

1.  Keep the battery and battery compartment clean and corrosion free. Dirty, corroded batteries can self-discharge, which will affect performance and life.

2.  Clean any terminal or post corrosion with a paste made from baking soda and water. Corrosion will be neutralized when the solution stops bubbling. Wash off with large quantities of water to avoid environmental damage.

3.  Periodically use a wire brush or steel wool to clean corrosion off battery posts and terminal ends. This will assure a low resistance in the connection.


Before storing your boat or leaving it unused for extended periods, consider the following best practices to prevent premature battery failure:

1.  Disconnect your battery to avoid self-discharge caused by parasitic loads, such as clocks or ground faults.

2.  Store the battery fully charged. Regularly check the state-of-charge every 90 days to ensure it remains above 75% throughout the storage period.

3.  Choose a cool, dry storage location with temperatures between 0ºC and 27ºC. Higher temperatures can accelerate self-discharge in batteries.
