Charging Procedure
The charging procedure starts as soon as the mains plug of
the battery charger is plugged into the socket outlet and the
battery is inserted into the charging compartment.
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery is
charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.
Rapid-charging Procedure

The rapid-charging procedure is indicated by flashing of the
green charge control LED.
Indication element of the battery: During the charging proce-
dure, 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 temper-
ature range, see section "Technical Data".

Continuous lighting of the green charge control LED sig-
nals that the battery is fully charged.
Additionally, a signal tone sounds for approx. 2 seconds,
which acoustically indicates that the battery is fully charged.
Afterwards, the battery can be removed for immediate use.
With no battery inserted, continuous lighting of the green
charge control LED indicates that the mains plug is plugged in-
to the socket and that the battery charger is ready for operation.
Battery Temperature below 0 °C or above 45 °C

Continuous lighting of the red LED indicates that the battery
temperature is not within the rapid-charging temperature
range of 0 °C – 45 °C. As soon as the allowable 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

If a different malfunction of the charging procedure is
present, this will be indicated through flashing of the red
charge control LED.
The charging procedure cannot be started and the battery
cannot be charged (see section "Troubleshooting").
Charging Advice
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaningful
and does not indicate a technical defect of the battery charg-
er.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Battery Cooling (Active Air Cooling)
The fan control integrated in the battery charger controls the
temperature of the inserted battery. When the battery tem-
perature is above 30 °C, a fan cools down the battery to the
optimal charging temperature. The switched-on fan produces
a fan noise.
The battery temperature is within the optimal charging tem-
perature range when the fan is not running. Another reason
for a non working fan might be that it is defective. In this case,
the charging time of the battery might be extended.
Working Advice
Battery Charge-control Indication
The battery is equipped with a charge-control indicator which
indicates its charge condition. The charge-control indicator
consists of 3 green LEDs.
