CHECKING AND CHARGING THE BATTERY
Charging method using a variable-current (voltage) charger
Adjust the voltage so that the
current is at the standard
charging level.
Set the time according to the
charging time suitable for the
open-circuit voltage.
Refer to "Battery condition
checking steps".
If charging requires more than 5 hours, it is advisable to check the
charging current after a lapse of 5 hours. If there is any change in the
amperage, readjust the voltage to obtain the standard charging
current.
Measure the battery open-circuit voltage after leaving the battery
unused for more than 30 minutes.
12.8 V or more --- Charging is complete.
12.7 V or less --- Recharging is required.
Under 12.0 V --- Replace the battery.
Measure the open-circuit
voltage prior to charging.
Connect a charged and
AMP meter to the battery
and start charging.
Make sure that the current
YES
is higher than the standard
charging current written on
the battery.
3-62
NOTE:
Voltage should be measured 30
minutes after the machine is stopped.
NOTE:
Set the charging voltage at 16 X 17 V.
(If the setting is lower, charging will be
insufficient. If too high, the battery will
be over-charged.)
By turning the charging
voltage adjust dial, set the
charging voltage at 20 X 24 V.
Monitor the amperage for
YES
3 X 5 minutes to check if the
standard charging current is
reached.
If the current does not
exceed the standard
charging current after 5
minutes, replace the battery.
