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. 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 4.
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.
Meaning of the Indication Elements
Flashing Green Battery Charge Indicator 2
The rapid-charging procedure is signalled
by a flashing green battery charge indica-
tor 2.
Note: The rapid-charging procedure is only possible when the
battery temperature is within the allowable charging temper-
ature range, see section "Technical Data".
Continuous Lighting of the Green Battery Charge Indica-
tor 2
Continuous lighting of the green battery
charge indicator 2 indicates that the bat-
tery is fully charged.
Additionally, a signal tone sounds for ap-
prox. 2 seconds, which acoustically indicates that the battery
is fully charged.
Afterwards, the battery can be removed for immediate use.
Bosch Power Tools
When the battery is not inserted, continuous lighting of the
AL 1860 CV
battery charge indicator 2 indicates that the mains plug is in-
Professional
serted in the socket and that the battery charger is ready for
operation.

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.
Battery Cooling (Active Air Cooling)
The fan control integrated in the battery charger controls the
temperature of the inserted battery. When the battery tem-
perature is above 30 °C, a fan cools down the battery to the
optimal charging temperature. The switched-on fan produces
a fan noise.
The battery temperature is within the optimal charging tem-
perature range when the fan is not running. Another reason

Continuous lighting of the red battery
charge indicator 3 indicates that the tem-
perature of the battery is not within the al-
lowable charging temperature range, see
A flashing red battery charge indicator 3
indicates a different malfunction of the
charging procedure, see section "Trouble-
shooting – Causes and Corrective Meas-
ures".
Causes and Corrective Meas-
–
Corrective Measure

Clean the battery contacts
(e.g. by inserting and remov-
ing the battery several times)
or replace the battery
Replace the battery
