Please observe the article number on the type plate of your battery
charger. The trade names of individual battery chargers may vary.
Operation
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.
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 7 is inserted into the charging compartment 6.
For charging Bosch batteries without contact APT 1, use
adapter 3.
To remove the adapter 3 from the charging compartment 6,
press release button 2.
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 Section "Technical Data".
Meaning of the Indication Elements
Flashing Green Battery Charge Indicator 4
The rapid-charging procedure is signalled
by a flashing green battery charge indica-
tor 4.
Afterwards, the battery can be removed for immediate use.
Note: The rapid-charging procedure is only possible when the
battery temperature is within the allowable charging temper-
ature range, see section "Technical Data".
