are to be used exclusively to connect Bosch industrial cord-
less screwdrivers to the 4EXACT constant voltage regulator.
Operating and storage conditions
The power tool is suitable only for operation at
enclosed work sites.
To ensure smooth operation, the permitted
ambient temperature should be between -5 °C and +50 °C
(23 °F and 122 °F), at a permitted relative humidity of
between 20% and 95%, free of condensation.
The battery should be stored at a temperature of between 0
°C (32 °F) and 45 °C (113 °F) in order to avoid damaging the
battery cells.
Charging process
Note: Batteries and chargers not included.
The mains plug pictured here may differ from that on your
power tool.
Make sure that the charger and battery are suitable
u
for your country's mains voltage.
Charger AL 2450 DV (see figure A)
Connect the charger (11) to the power supply with the
mains plug (12) and insert the battery (5) correctly into the
charging slot on the charger.
Do not use force to insert/remove the battery. Batter-
u
ies with APT contact (Akku Pack Top, English: battery
pack top) are designed such that they can only be inser-
ted into the power tool or charger in the correct position.
The green LED indicator (13) will start to flash. This indic-
ates that charging current is flowing. The charging process
will stop automatically once the battery is fully charged.
When the charging process is complete, the green LED indic-
ator will stop flashing and will be continuously lit. An sound
is emitted for approximately two seconds, indicating that the
battery is fully charged.
If the red LED indicator (14) is continuously lit, this indicates
that charging is being carried out with a reduced charging
current. If the red LED indicator is flashing, charging is not
possible.

Note: As an alternative to battery operation, industrial cord-
less screwdrivers can also be operated with a constant
voltage regulator. Constant voltage regulator and voltage ad-
apter not included.
The mains plug pictured here may differ from that on your
power tool.
Make sure that the constant voltage regulator is suit-
u
able for your country's mains voltage.
In addition to the 4EXACT constant voltage regulator and
compatible mains cable, you will also need a voltage adapter
with the same rated voltage as your screwdriver.
The voltage on the constant voltage regulator (LED in-
u
dicator) must match the voltage of the screwdriver.
The constant voltage regulator is only suitable for Bosch
industrial cordless screwdrivers from the EXACT, ANGLE
EXACT and BT‑EXACT series with a voltage of between
9.6 V and 14.4 V. Otherwise there is a risk of fire and ex-
plosion.
Connecting to the power supply
Note: On delivery, neither a battery nor a voltage adapter
are inserted in the power tool.
Never store batteries inside a battery-powered tool.
u
Batteries will remain functional for longer and can be
charged more easily if they are stored separately. Please
remember to fully charge the battery prior to use after
longer periods of storage.
Battery Charging
Charge the battery using a suitable charger before inserting
it in the power tool. The charging process in described in de-
tail in the charger's operating manual and the instructions of
this manual (see (see "Charging process", page 19)).
The battery features NTC temperature monitoring, which
only permits charging in a temperature range between 0 °C
(+32 °F) and 45 °C (+113 °F). This achieves a long battery
life. If used correctly, the battery can withstand up to 3000
charging cycles.
A new battery or one that has not been used for a long time
will only operate at full capacity after approximately five
