Important Information
Caring for NiCd and NiMH battery packs
This section contains information on how to obtain optimum service life
from your battery pack. Use only system-compatible chargers for charging
the batteries!
1 Both discharged and charged battery packs without built-in electronics
can be stored during extended periods (up to several years) without
damage at a storage temperature of 0 °C to 35 °C when separated from
the units. Charged batteries discharge themselves within a few weeks or
months. This self-discharge is harmless since this is no deep discharge.
2 Battery packs with built-in electronics (e.g. protective circuit for realizing the
explosion protection in explosion-proof battery packs) discharge themselves
completely after some time due to the current consumption of the built-in
electronics even when disconnected from the unit and will be permanently
damaged by this deep discharge. To avoid this noxious 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
