While many wakeboard boat owners diligently keep their batteries charged while their boat is in storage during the off-season, they often overlook in-season battery maintenance. The key to long battery life is making sure your battery’s voltage never drops below 12.4 volts, which can easily happen if you run your stereo for long periods of time while your engine is off. If this happens, make sure you fully charge your battery when you’re done using your boat for the day.
If you run your battery down listening to your stereo during the day and only have a five-minute ride back to the dock, you might not give your alternator enough time to fully-charge your battery. If you take your boat out at night, check your voltage and hook your battery up to a maintainer, if needed. If you leave your boat in the water and don’t have access to shore power, consider a solar charger. Just make sure that any charger or maintainer you use is microprocessor-controlled and offers protection to prevent overcharging.
