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.)
Adjust the voltage to obtain the

Adjust the char ging voltage to
20 ~ 25V.
Monitor the amperage for 3 ~ 5
minutes. Is the standard charg-
ing amperage exceeded?
If the amperage does not ex-

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 amperage.
Leave the battery unused for more than 30 minutes before measuring
its open-circuit voltage.
12.8 V J Charging is complete.
12.0 ~ 12.7 V J Recharging is required.
Under 12.0 V J Replace the battery.
