(Battery:BDC72 Charger:CDC77)
• Do not charge the battery just after charging is completed. Battery performance may decline.
• The charger is for indoor use only. Do not use outdoors.
• Batteries cannot be charged when the temperature is outside the charging temperature range. Be sure to
charge the battery within the charging temperature range.
• 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.
