The battery is equipped with temperature mon-
itoring that allows charging only in the tempera-
ture range between 0 °C and 45 °C. In this man-
ner, a high battery service life is achieved.
Note: The battery is supplied partially charged.
To ensure full capacity of the battery, complete-
ly charge the battery in the battery charger be-
fore using your power tool for the first time.
The lithium ion battery can be charged at any
time without reducing its service life. Interrupt-
ing the charging procedure does not damage the
battery.
The lithium-ion battery is protected against
deep discharging when used in the product.
When the battery is discharged the product is
switched off by a protective circuit and the
product no longer operates.
Do not continue to press the On/Off switch
after an automatic shut-off of the machine.
The battery can become damaged.
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 8 is inserted in-
to the charging compartment 16.
Due to the intelligent charging method, the
charging condition of the battery is automatical-
ly detected and the battery is charged with the
optimum charging current, depending on bat-
tery temperature and voltage.
This gives longer life to the battery and always
leaves it fully charged when kept in the charger
for storage.
Meaning of the Indication Elements
Control of the charging procedure is indicated
via the charge control LEDs 18 and 19:
Rapid-charging Procedure
The rapid-charging procedure is
indicated by flashing of the
green charge control LED 19.
Bosch Power Tools
During the 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 pos-
sible when the battery temperature is within the
allowable charging temperature range, see sec-
tion "Technical Data".
Battery Charged
Continuous lighting of the
green charge control LED 19
signals 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 im-
mediate use.
With no battery inserted, continuous lighting of
the green charge control LED 19 indicates that
the mains plug is plugged into the socket and
that the battery charger is ready for operation.
Battery Temperature below 0 °C and above
45 °C
Continuous lighting of the red
LED 18 indicates that the bat-
tery 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 charg-
ing.
When the battery is not within the allowable
temperature range, the red battery LED lights
up when inserting the battery 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 con-
trol LED 18.
