Starting Operation
 Observe the mains voltage! The voltage of the power
supply must correspond with the data given on the name-
plate of the battery charger. Battery chargers marked with
230 V can also be operated with 220 V.
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 1 is inserted into the charging compartment 3.
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.
Note: The charging procedure is only possible when the bat-
tery temperature is within the allowable charging tempera-
ture range, see "Technical Data" section.
Meaning of the Indication Elements
Flashing Battery Charge Indicator 2
The charging procedure is signalled by a
flashing battery charge indicator 2.
Continuous Lighting of the Battery Charge Indicator 2
Continuous lighting of the battery
charge indicator 2 indicates that the
battery is fully charged or that the
temperature of the battery is not with-
in the allowable charging temperature range, and cannot be
charged for this reason. The battery is charged as soon as the
allowable charging temperature range is reached.
Bosch Power Tools
When the battery is not inserted, continuous lighting of the
battery charge indicator 2 indicates that the mains plug is in-
AL 1820 CV
serted in the socket and that the battery charger is ready for

Working 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.
Maintenance and Service
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
