BATTERY INSPECTION AND CHARGING (TT-R90E)
Charging method using a constant voltage charger
YES
Charge the battery until the charging
voltage reaches 15 V.
NOTE:
Set the charging time to a maximum of 20 hours.
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 batteries.
Measure the open-circuit
voltage prior to charging.
Connect a charger and
ammeter to the battery
and start charging.
Is the amperage higher
than
charging amperage writ-
ten on the battery?
CAUTION:
NOTE:
Leave the battery unused for more
than 30 minutes before measuring its
open-circuit voltage.

standard
This type of battery charger cannot
charge an MF battery. A variable
voltage charger is recommended.
