Operation
Start-up
Note the mains voltage! The voltage of the power source
u
must match the voltage specified on the rating plate of
the charger. Chargers marked with 230 V can also be op-
erated with 220 V.
Charging process
The charging process begins as soon as the mains plug for
the charger is inserted into the mains socket and the battery
(1) is inserted into the charging slot (2).
Thanks to the intelligent charging process, the charge condi-
tion of the battery is automatically detected and then
charged up with the optimal charge current depending on
battery temperature and voltage.
In this way, the battery is treated with care and remains per-
manently fully charged when it is stored in the charger.
Note: The charging process is only possible when the tem-
perature of the battery is within the permitted charging tem-
perature range, see section "Technical data".
What the display elements mean
Flashing battery charge indicator (3)
The charging process is indicated by the flash-
ing of the battery charge indicator (3).
Solid light on battery charge indicator (3)
A solid light on the battery charge indicator
(3) signals that the battery is fully charged or
that the temperature of the battery is not
within the permitted charging temperature
range, and can therefore not be charged. The battery is
charged as soon as the allowable charging temperature
range is reached.
When the battery is not inserted, a solid light on the battery
charge indicator (3) signals that the mains plug is inserted in
the plug socket and that the charger is ready for operation.

Practical advice
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
When the charger is used continuously, or for several con-
secutive charge cycles without interruption, the charger may
heat up. This is, however, harmless and does not indicate
that the charger has a technical defect.
Maintenance and Service
Maintenance and cleaning
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
