Technical Data
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
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 Indica-
tor 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.
