surfaces of the battery with one another by a conductive material
involves a fire and explosion hazard to the battery.
• After two years of normal use or storage, a lithium ion battery will have
lost about half of its initial capacity due to ageing. The battery capacity is
also additionally reduced by frequent charge/unloading cycles. Such
capacity losses are normal and will not give rise to a warranty claim.
Care information for lithium ion batteries
This section contains information on how to obtain optimum service life
from your battery.
1 Use only the system-compatible charger for charging the batteries!
2 Half-charged batteries can be stored separately from the units for an
extended period (up to several months) at a storage temperature of
0 °C to 15 °C.
3 Batteries mounted on the unit become discharged during an extended
storage period due to the idling current consumption of the phone and
the battery. Charge the batteries in the unit once before the storage
period and then at regular 3-month intervals.
4 Charge flat batteries immediately by placing the unit into its charger.
Discharged batteries can be identified by the ‘Battery flat‘ message or by
the failing unit function. Discharged batteries can be identified by the
‘Battery flat‘ message or by the failing unit function.
5 If the service times of the unit are considerably shorter after extended
unit use, you should replace the battery by a new one.
6 The strongest adverse effect on battery service life for which we cannot
be held responsible is any heavy heating of the battery during storage or
operation. For this reason, never leave the handset or the batteries in
the blazing sun or near heat sources for an extended period.
