CHECKING AND CHARGING THE BATTERY
Charging method using a variable-current (voltage) charger
Charger
Ammeter
Measure the open-circuit
voltage prior to charging.
NOTE:
Leave the battery unused for more
than 30 minutes before measuring its
opencircuit voltage.
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.)
Set the timer to the charging
time determined by the
opencircuit voltage.
Refer to “CHECKING AND
CHARGING THE BATTERY”.
If the amperage does not ex-
ceed the standard charging am-
perage after 5 minutes, 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 amperage.
Leave the battery unused for more than 30 minutes before measuring
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.
