Charging method using a variable voltage charger
Charger
YES
Adjust the voltage to obtain
the standard charging amper-
age.
Set the timer to the charging
time determined by the open-
circuit voltage.
Refer
to
INSPECTION AND CHARG-
ING" section.
If the required charging time exceeds 5 hours, it is advisable to check
the charging amperage after 5 hours. If there is any change in the
amperage, readjust the voltage to obtain the standard charging amper-
age.
Leave the battery unused for more than 30 minutes before measuring
its open-circuit voltage.

12.0 ~ 12.7 V
Under 12.0 V

Charging is complete.
→
Recharging is required.
→
Replace the battery.
Measure the open-circuit
voltage prior to charging.
Connect a charger and
ammeter to the battery
and start charging.
Is the amperage higher
than the standard charg-
ing amperage written on
the battery?
Adjust the charging voltage to
20 ~ 25 V.
Monitor the amperage for 3 ~
5 minutes. Is
charging amperage exceeded?
3 - 54

NOTE:
Leave the battery unused for
more than 30 minutes before
measuring its open-circuit voltage.
NOTE:
Set the charging voltage to 16-
17 V. (If the charging voltage is
lower, charging will be insuffi-
cient, if it is higher, the battery will
be over-charged.)
NO
the
standard
NO
If the amperage does not
exceed the standard charg-
ing amperage after 5 minutes,
replace the battery.
