Figure 10 Fastening the battery.
The lithium battery needs no charging and for this reason there is a blocking diode
which prevents charging from the serial measurement board.
Two types of lithium battery are available:
- a 3-cell battery, art.no. 3HAB 9999-1
- a 6-cell battery, art.no. 3HAB 9999-2
The service life of the lithium battery depends on how frequently the user switches off
the power. The estimated max service life in years for the different types of lithium
battery and the recommended exchange intervals are shown below:
* Because of material ageing the maximum service life is 5 years.
Voltage of batteries, measured at power off:
User type: Exchange 3-cell: Exchange 6-cell:

2. Weekend power off + user type 1 every 2 years every 4 years
3. Nightly power off + user types 1 and 2 every year every 2 years
