Thanks to the intelligent charging process, the state of charge
of the battery is automatically detected and then charged up
with the optimal charge current depending on battery temper-
ature and voltage.
In this way, the battery is treated with care and remains per-
manently fully charged when it is stored in the battery charger.
A significantly reduced operating time after charging indicates
that the battery has deteriorated and must be replaced.
When the charger is used continuously, or for several consecut-
ive charge cycles without interruption, the charger may heat
up. This is, however, harmless and does not indicate that the
charger has a technical defect.

What the display elements mean
Flashing light battery charge indicator
The rapid-charging procedure is indicated by the
quick flashing of the green battery charge indic-
ator (3).
The battery can be removed at any time and
used.
Once approx. 80% of the battery capacity has been reached,
the flashing of the green battery charge indicator will slow
down. The rapid-charging process is now completed. If the bat-
tery remains in the charger, the charging process will be per-
formed at a slower pace.

Continuous light green battery charge
indicator
The continuous light of the green battery charge
indicator (3) signals that the battery is fully
charged. The battery can then be removed for im-
mediate use.
When there is no battery connected, the continu-
ous light of the battery charge indicator (3) signals that the
mains plug is plugged into the plug socket and that the charger
is ready to be used.
Continuous light red temperature monitoring
indicator
The continuous light of the red indicator (2) sig-
nals that the temperature of the battery is outside
of the permitted charging temperature range (0–
45 °C). The charging process begins as soon as
the permitted temperature range has been
reached.
Flashing light red error indicator
The flashing light of the red indicator (2) signals
that the charging process has been interrupted
by a different fault (see "Battery is not being
≈35
charged", page 7).
