Battery and charger heat up during the
charging process. This is perfectly normal!
Lithium-ion batteries do not exhibit the
established "memory effect". Nevertheless,
a battery should be completely discharged
before charging and the charging process
should always be fully completed.
If batteries are not used for an extended
period of time, store them partially charged
in a cool place.
Charging process
CAUTION!
Insert only original batteries in the supplied
charger.
 Insert the charger mains plug. The display
backlighting lights up green for 2 seconds
and then goes out again. OK is displayed.
 Insert the battery fully into the charger
until it clicks into place.
– The time remaining in the charging
process (until the battery is fully
charged) and a graphic representation
of the state of charge are shown
alternately in the display.
– The display backlighting lights up
orange when the battery is charged
less than 80%.
– When the battery charge reaches 80%
