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
2
.
The battery charge indicator
3
is not a charge-control indica-
tor. The lit indicator signalises the flow of charging current.
The charging procedure is not ended automatically. There-
fore, disconnect the battery charger from the mains supply af-
ter the battery has been charged and remove the battery. A
temperature increase of the battery indicates that the battery
is fully charged.
Troubleshooting – Causes and Corrective
Measures
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 charger.
A battery that is new or that has not been used for a longer pe-
riod will not achieve its full capacity until after approx. 5
charging and discharging cycles. Leave such a battery in the
battery charger until it has warmed up considerably.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
