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 indicator 2.
The battery can be removed at any time and
used.
Note: The charging procedure is only possible when the bat-
tery temperature is within the allowable charging tempera-
ture range, see "Technical Data" section.
Once approx. 80 % of the battery capacity has
been reached, the flashing of the green battery
80 %
charge indicator slows down. The rapid-charg-
ing process is now completed. If the battery re-
mains in the charger, the charging process will be completed
in the Long Life charging mode.
Continuous Lighting of the Green Battery Charge
Indicator 2
Continuous lighting of the green battery
charge indicator 2 indicates that the battery is
fully charged.
Afterwards, the battery can be removed for immediate use.
When the battery is not inserted, continuous lighting of the
battery charge indicator 2 indicates that the mains plug is in-
serted in the socket and that the battery charger is ready for
operation.
Continuous Lighting of the Red Battery Charge Indicator 3
The continuous light of the red battery charge
indicator 3 shows that the temperature of the
battery is outside of the permitted charge-tem-
perature range, see section "Technical Data".
The charging process begins as soon as the permitted tem-
perature range has been reached.

Flashing Red Battery Charge Indicator 3
A flashing red battery charge indicator 3 indi-
cates a different malfunction of the charging
procedure, see section "Troubleshooting –
Causes and Corrective Measures".
Indications on 36 V Batteries
During the charging procedure, the three green charge-con-
trol indicators 5 of the battery light up one after the other
and briefly go out. The battery is fully charged when the three
green indicators light up continuously. After approx.
5 minutes after the battery has been fully charged, the three
green indicators go out again.
When the red temperature control indicator 6 lights up
when placing the battery into the charger, the temperature of
the battery is not within the charge-temperature range (see
section "Technical Data"). The battery cannot be charged un-
til after the allowable operating temperature range has been
reached.
Troubleshooting – Causes and Corrective
Measures
Cause
Flashing red battery charge indicator 3
No charging procedure possible
Battery not (properly)
inserted
Battery contacts
contaminated
Battery pack defective
Battery charge indicators 2 or 3 do not light up
Mains plug of battery charger
not plugged in (properly)
Socket outlet, mains cable or
battery charger defective

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 into the charger monitors the tem-
perature of the inserted battery. If the battery temperature is
above approx. 10 °C, the battery will be cooled by a fan. The
fan generates a ventilation sound when switched on.
If the fan is not running, the battery temperature is within the
optimum charge-temperature range or the fan is defective. In
this case, the charging time of the battery may increase.
Corrective Measure
Properly insert battery into
battery charger
Clean the battery contacts
(e.g. by inserting and remov-
ing the battery several times)
or replace the battery
Replace the battery
Insert mains plug (fully) into
the socket outlet
Check the mains voltage;
have the battery charger
checked by an authorised
after-sales service agent for
Bosch power tools
