CHECKING AND CHARGING THE BATTERY
Charging method using a constant voltage charger
YES
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 → Charging is complete.
12.0 ~ 12.7 V → Recharging is required.
Under 12.0 V → Replace the battery.
Constant amperage chargers are
not suitable for charging MF bat-
teries.
Measure the open-circuit
voltage prior to charging.
Connect a charger and
ammeter to the battery and
start charging.
Is the amperage higher
than the standard charging
amperage written on the
battery?
NOTE:
Set the charging time to a maxi-
mum of 20 hours.
CAUTION:
This type of battery charger cannot
charge an MF battery. A variable
voltage- charger is recommended.
