3-44
Measure the open-circuit
voltage prior to charging.
Connect a charger and am-
meter to the battery and
start charging.
Is the amperage higher
than the standard charging
amperage written on the
battery?
Adjust the charging voltage to
20
25 V.
Adjust the voltage to obtain the
standard charging amperage.
Monitor the amperage for 3
5 minutes. Is the standard
charging amperage exceed-
ed?
Set the timer to the charging
time determined by the open-
circuit voltage.
Refer to “CHECKING AND
CHARGING THE BATTERY”.
If the amperage does not
exceed the standard charg-
ing amperage after 5 min-
utes, replace the battery.
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 am-
perage, readjust the voltage to obtain the standard charging amper-
age.
Leave the battery unused for more than 30 minutes before measur-
ing its open-circuit voltage.
12.8 V
Charging is complete.
12.0 12.7 V Recharging is required.
Under 12.0 V Replace the battery.

NO
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 charg-
ing will be insufficient, if it is higher, the
battery will be over-charged.)
