lows charging only in the temperature range between 0 °C
and 35 °C. In this manner, a high battery service life is
achieved.
Note: The battery is supplied partially charged. To ensure
full battery capacity, completely charge the battery in the
battery charger before using for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the battery.
The "Electronic Cell Protection (ECP)" protects the lithium-
ion battery against deep discharging. When the battery is

Rapid-charging Procedure
charging procedure, the three green LEDs light up one after
the other and briefly go out. The battery is fully charged
when the three green LEDs light up continuously. The three
LEDs go out again approx. 5 minutes after the battery has
been fully charged.
Note: The rapid-charging procedure is only possible when
the battery temperature is within the allowable charging
temperature range, see section "Technical Data".
Battery charged
2 seconds, which acoustically indicates that the battery is
fully charged.
Afterwards, the battery can be removed for immediate use.
When the battery is not inserted, continuous lighting of the
LED indicator indicates that the mains plug is inserted in the
socket outlet and that the battery charger is ready for opera-
tion.
Battery Temperature below 0°C or above 45°C
range, see section "Technical Data". As soon as the allowable
charging temperature range is reached, the battery charger
automatically switches to rapid charging.
When the battery is not within the allowable temperature
range, the red battery LED lights up when inserting the bat-
tery into the battery charger.
No Charging Procedure Possible
The charging procedure cannot be started and the battery
cannot be charged (see section Troubleshooting).
The rapid-charging procedure is indicated by
flashing of the green battery charge indicator.
Indication element of the battery: During the
Continuous lighting of the green LED indic-
ator indicates that the battery is fully charged.
Additionally, a signal tone sounds for approx.
Continuous lighting of the red LED indicator
indicates that the temperature of the battery is
not within the allowable charging temperature
If a different malfunction of the charging pro-
cedure is present, this will be indicated
through flashing of the red LED indicator.
