harmful to a battery, and should not be
used for topping up.
1. Check the electrolyte level at least once a
month. Fill to the manufacturer's recom-
mended level when necessary. Top up
only with distilled water (or pure de-ion-
ized water suitable to use in batteries).
2. Always keep the battery 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.
NOTE:
Consult a Yamaha dealer when charging or
re-charging batteries.
