CHECKING AND CHARGING THE BATTERY
Charging method using a variable-current (voltage) charger
Charger
AMP meter
Adjust the voltage so that the
current is at the standard charg-
ing level.
Set the time according to the
charging time suitable for the
open-circuit voltage.
Refer to
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 charger 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.
"Battery condition
3 - 61
NOTE:
Voltage should be measured 30
minutes after the machine is
stopped.
NOTE:
Set the charging voltage at
16 ~ 17 V. (If the setting
lower, charging will be insuffi-
cient. If too high, the battery
will be over-charged.
By turning the charging voltage
adjust dial, set the charging at
20 ~ 24 V.
Monitor the amperage for 3 ~ 5
YES
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 bat-
tery.
