POWER SOURCE AND CHARGING
14.1 Battery Charging
Be sure to charge the battery fully before using it for the first time or after not using it for long
periods.
•
The charger will become rather hot during use. This is normal.
•
Do not use to charge batteries other than those specified.
•
The charger is for indoor use only. Do not use outdoors.
•
Batteries cannot be charged, even when the charging lamp is flashing, when the temperature is
outside the charging temperature range.
•
Do not charge the battery just after charging is completed. Battery performance may decline.
•
Remove batteries from the charger before putting into storage.
•
When not in use, disconnect the power cable plug from the wall outlet.
•
Store the battery in a dry room where the temperature is within the following ranges. For long-term
storage, the battery should be charged at least once every six months.
•
Batteries generate power using a chemical reaction and as a result have a limited lifetime. Even
when in storage and not used for long periods, battery capacity deteriorates with the passage of
time. This may result in the operating time of the battery shortening despite having been charged
correctly. In this event, a new battery is required.
PROCEDURE
1
Connect the power cable to the charger and plug the
charger into the wall outlet.
2
Mount the battery in the charger by matching the
grooves on the battery with the guides on the charger.
When charging starts, the lamp starts blinking.
3
Charging takes approximately 2.5 hours (BDC46C:
25°C).
The lamp lights when charging is finished.
4
Remove the battery and unplug the charger.
•
Slots 1 and 2:
The charger starts charging the battery mounted first. If you place two batteries in
the charger, the battery in slot 1 is charged first, and then the battery in slot 2.
(step 2)
•
Charging lamp: The charging lamp is off when the charger is outside the charging temperature
range or when the battery is mounted incorrectly. If the lamp is still off after the
charger falls within its charging temperature range and the battery is mounted
again, contact your local dealer. (steps 2 and 3)
•
Charging time: BDC46C: about 2.5 hours (at 25°C)
BDC70 (optional accessory): about 5.5 hours (at 25°C)
(Charging can take longer than the times stated above when temperatures are
either especially high or low).
