Quick Tip – Essential Battery Maintenance for Spring

Spring is here, and that means it’s time to get your boat battery ready for the season. A dead battery can ruin any boating trip, so take these quick steps to ensure reliable starts all summer long.

Check the Connections

Remove any corrosion from terminal posts using a wire brush. Apply dielectric grease to prevent future buildup. Loose connections are the number one cause of starting problems.

Test the Charge

Use a multimeter to check voltage. A fully charged marine battery should read 12.6 volts or higher. Anything below 12.4 volts indicates it needs charging before your first trip.

Inspect for Damage

Look for cracks, bulging, or leaking. Any physical damage means it’s time for a replacement. Don’t risk being stranded on the water with a failing battery.

Taking fifteen minutes now saves hours of frustration later. Your boat deserves proper battery care.
