CHECKING AND CHARGING THE BATTERY
Charging method using a variable-current (voltage) charger
Charger
YES
Adjust the voltage to obtain the
standard charging amperage.
Set the timer to the charging
time determined by the open-
circuit voltage.
Refer to "CHECKING
CHARGING 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 amperage,
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.
Measure the open-circuit
voltage prior to charging.
Ammeter
Connect a charger and
ammeter to the battery and
start charging.
Is the amperage higher
than the standard charging
amperage written on the
battery?
YES
AND

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 insufficient, if it is higher,
the battery will be over-
charged.)
NO
Adjust the charging voltage to
20 ~ 25 V.
Monitor the amperage for 3 ~ 5
minutes. Is the standard charg-
ing amperage exceeded?
NO
If the amperage does
exceed the standard charging
amperage after 5 minutes,
replace the battery.
