BATTERY INSPECTION AND CHARGING
Charging method using a constant voltage charger
Measure the open-circuit
voltage prior to charging.
Connect a charger and
ammeter to the battery
and start charging.
NO
YES Is the amperage higher
than the standard
charging amperage writ-
ten on the battery?
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. This type of battery charger cannot
charge an MF battery. A variable
voltage charger is recommended.
Leave the battery unused for more
than 30 minutes before measuring
its open-circuit voltage.
Set the charging time to a maximum of 20 hours.
Constant amperage chargers are not
suitable for charging MF batteries.
