A poorly maintained battery will quickly
deteriorate.
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 bat-
teries).

Ordinary tap-water contains minerals
harmful to a battery, and should not be
used for topping-up.
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.
