CHECKING AND CHARGING THE BATTERY
Charging method using a variable voltage charger
Charger
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 AND
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 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
Under 12.0 V ! Replace the battery.
Measure the open-circuit
Ammeter
voltage prior to charging.
Connect a charger and am-
meter to the battery and
start charging.
Is the amperage higher
YES
than the standard charging
amperage written on the
battery?
12.7 V ! Recharging is required.
Adjust the charging voltage to
20 25 V.
Monitor the amperage for 3
YES
5 minutes. Is the standard
charging amperage exceed-
ed?
If the amperage does not
exceed the standard charg-
ing amperage after 5 min-
utes, replace the battery.

circuit voltage.
NOTE:
Set the charging voltage to 16

will be insufficient, if it is higher, the bat-
tery will be over-charged.)
