TIP Assuming the charging process started from an empty state, the time it takes from start to
completion of the charging process is typically 2.5 to 3 hours.
If charging in a location with a high temperature or if charging a brand new battery, this may
take longer.
… Check to ensure that charging is complete.
When charging is complete, the battery capacity
indicator lamps and the charge lamp (green) on
the charger turn off.
After charging is complete, you can check the
charged capacity by pressing the battery indica-
tor switch.
If not all of the lamps turn on, the following could
have occurred:
• While charging, the temperature of the battery
rose excessively, causing the protection mech-
anism to abort the charging process.
• The battery deterioration has advanced and
the capacity is decreasing.
and so on.
 Unplug the power cord from the power outlet.
● Do not pull on the power cord. This can cause the wires to break.
 Remove the battery from the charger.
If you want to store the battery in this state, put
the protective cap on.
