Commissioning the device
3.3 Power supply
Service life of the battery
Due to the technology used, the capacity of the lithium ion battery used in the device
reduces with each charge/discharge process. A gradual reduction in capacity also takes
place if stored at too high or too low temperatures. The operating times of one battery charge
in a network-independent operation can therefore gradually reduce over time.
The battery has a typical life span of c. 300 charges and is therefore designed in such a way
that with standard handling within six months after purchase of your device it can still be
charged and discharged. A loss of capacity over time is technology-dependent and, as with
all manufacturers of comparable devices, it is excluded from the warranty. In the case of a
significant drop of efficiency we recommend that you replace the battery. Use only Siemens
original spare parts.
You should note the following with regard to the life span of the battery:
● If possible, the battery should always be completely discharged/charged.
● Frequency of use: The more often the battery is used, the faster it reaches the end of its
effective life span. A lithium ion battery has a typical life of around 300 charge cycles.
