PRECAUTIONS FOR CHARGING BATTERY
k k
WARNING
When charging the battery, if the battery is not handled
correctly, it is dangerous that the battery may explode. Al-
ways follow the instructions in “PRECAUTIONS FOR DIS-
CHARGED BATTERY (3-228)” and the instruction manual
accompanying the charger, and do as follows.
• Set the voltage of the charger to match the voltage of
the battery to be charged. If the correct voltage is not
selected, the charger may overheat and cause an ex-
plosion.
• Connect the positive (+) charger clip of the charger to
the positive (+) terminal of the battery, then connect
the negative (-) charger clip of the charger to the nega-
tive (-) terminal of the battery. Be sure to attach the
clips securely.
• Set the charging current to 1/10 of the value of the rat-
ed battery capacity; when performing rapid charging,
set it to less than the rated battery capacity.
If the charger current is too high, the electrolyte will
leak or the battery cells will dry up, and this may cause
the battery to catch fire and explode.
• If the battery electrolyte is frozen, do not charge the
battery or start the engine with a different power
source. It is dangerous that this may ignite the battery
electrolyte and cause the battery to explode.
• Do not use or charge the battery if the battery charge
indicator is bright white or, if the battery does not have
an indicator, if the level of the electrolyte is below the
LOWER line (minimum level). This may cause an ex-
plosion.
