lTo charge

1Plug the charger into the outlet.

2Connect the charger connector to the battery, then charging will start. Preparatory charging will start.* (The red lamp of the charger will blink.)

When the preparatory charging is completed, the charging status will be switched to quick charging automatically. (The red lamp of the charger will light.)

3Charging will take approximately 2.5 hours. (The green lamp will illuminate.)

4After charging, remove the battery from the charger. Remove the charger from the outlet.

lTo refresh

Press the refresh switch after starting charging above steps (1, 2 ), then discharging will start. Confirm the yellow lamp illuminates.

After discharging is finished , charging will start automatically. Time discharging battery charged fully is approximately 12 hours.

lFor refreshing

Rechargeable battery can be used repeatedly by charging. If charging is repeated by the state that capacity of the battery still left, operating time of the battery may shorten. In this case, the voltage of the battery will be recovered by refreshing and operating time can be improved.

*About Preparatory charging

Before quick charging, the battery is charged using small amount current to measure its temperature and voltage.

When the temperature and voltage is within a range, the charging status will change to quick charging.
