Operation
Start-up
Note the mains voltage! The voltage of the power source
u
must match the voltage specified on the rating plate of
the charger. Chargers marked with 230 V can also be op-
erated with 220 V.
Charging process
The charging process begins as soon as the mains plug for
the charger is inserted into the mains socket and the battery
(1) is inserted into the charging slot (2).
Thanks to the intelligent charging process, the charge condi-
tion of the battery is automatically detected and then
charged up with the optimal charge current depending on
battery temperature and voltage.
In this way, the battery is treated with care and remains per-
manently fully charged when it is stored in the charger.
