Charging method using a constant voltage charger
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 am-
perage written on the bat-
tery?
TIP
Set the charging time to a maximum
of 20 hours.
TIP
Leave the battery unused for more
than 30 minutes before measuring
its opencircuit voltage.
Charge the battery until the charging
voltage reaches 15 V.
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 re-
quired.
Under 12.0 V J Replace the battery.
NOTICE
Constant amperage chargers are not
suitable for charging MF batteries.
