Cautions on Charging Battery
Fig. 5-124
Improper handling when charging the battery
may cause the battery to explode. Follow the
manuals attached to the machine and the
charger, and always observe the followings.
• Adjust the charger voltage to suit the voltage of
the battery to charge. Mistake in adjusting the
voltage may cause explosions due to overheat
and ignition of the charger.
• Securely fix the (+) charge clip of the charger to
the (+) terminal of the battery, then securely fix
the (-) charge clip to (-) terminal of the battery.
• Set the charge current to no more than 1/10 of
the rated capacity of the battery.
• Do not use quick charging.
• Excessive charge current may cause leap fire
and explosion caused by fluid leak or fluid
deficiency.
When charging the battery mounted to the
machine:
• Abnormal voltage may be applied to the
alternator, resulting in the breakage.
Disconnect the battery terminal wires before
charging the battery.
• Stop charging when the battery was
overheated (fluid temperature exceeded
45 °C).
• Stop charging promptly once the charging is
completed.
Charging even after the charging is completed
will;
(1) overheat the battery
(2) reduce the electrolyte level
(3) cause failures in battery
• Never inverse the connection of [(+) terminal
and (-) terminal]. Doing so can cause damage
on alternator.
• Remove the battery cable when handling the
battery other than for battery electrolyte level
check and specific gravity measurement.
