1)Check the electrolyte level at least once a month. Fill to the manufacturer’s rec- ommended level when necessary. Top up only with distilled water (or pure de- ionized water suitable to use in batter- ies).
2)Keep the battery always in a good state of charge. Installing a voltmeter will help you monitor your battery. If you will not use the boat for a month or more, remove the battery from the boat and store it in a cool, dark place. Completely recharge the battery before using it.
3)If the battery will be stored for longer than a month, check the specific gravity of the fluid at least once a month and recharge the battery when it is low.
