battery, a special (constant-voltage) battery
charger is required. Using a conventional bat-
tery charger will damage the battery. If you do
not have access to a constant-voltage battery
charger, have a Yamaha dealer charge yourbattery.
To store the batteryIf the ATV will not be used for more than one
month, remove the battery, fully charge it, and
then place it in a cool, dry place.If the battery will be stored for more than two
months, check it at least once a month and fully
charge it if necessary.
