Important Information
deep discharge during extended storage periods, charge such battery
packs once before storing them and then regularly every 3 months. The
allowed storage temperature for extended storage is also between 0 °C
and 35 °C.
3 Always charge new or stored battery packs without any interruption
before using them. The same applies to battery packs of an unknown
charge degree. The recommended charging times can be taken from the
Operating Manual.
4 If you detect that new battery packs or packs that have been stored for
an extended period considerably fall below the service time stated in
your Operating Manual of your unit following the first charging (item 3),
please apply the battery pack cure described in item 8.
5 Charge discharged batteries without delay. Or at least separate them
from the unit. This avoids deep discharge of the battery packs -
However, pay attention to the particularities regarding the storage of
battery packs with built-in electronics as mentioned above in item 2!
Discharged battery packs can be identified by the "battery-low" indication
or by the failing unit function.
6 Ensure that the battery pack is not permanently 100% charged. For the
battery-powered unit, this means: Do not put it back into the charger
immediately after a few or short uses, but leave it in stand-by mode for
an extended time, e.g. overnight next to the charger, if possible until the
"battery-low" indication appears on the unit. Regular and complete
discharging and charging of the battery pack avoids early capacity
losses of the cells.
7 Do not constantly change half-charged or even almost fully charged
battery packs. When operational reasons request changing the battery
pack, you should extend the change intervals so that the battery pack is
discharged to the greatest possible extent before it is replaced, but
without endangering safe unit function due to a discharged battery
(provide a operational standby period!).
8 If the service times of the unit are considerably shorter after extended
use of the unit, try the battery pack cure:
Discharging: Use the unit (handset) until the "battery-low" indication
appears.
Charging: Charge the battery pack as described in the Operating Manual.
