7.5.1 Batteries to Power the Device
The device is powered by a
B-03
battery with a nominal voltage of 3.6 V and a capacity of 17 Ah.
Instead of this battery, the device ELCOR
plus
can be equipped with a
B-03D
battery that has a
higher capacity (30 Ah).
The modem module is not powered from this battery in the device variant with the modem. Its
power supply is provided by its own battery.
During operation, the consumed capacity is measured and calculated. The remaining battery
capacity is stored directly in the internal battery memory.
The battery life depends mainly on the device configuration, the frequency of communication, the
time of display illumination and weather conditions.
Defined conditions for declared battery life:
30 s measurement period (not applicable to encoders)
archive period of data archive 1 hour
period of input pulses from the gas meter ≤10 Hz
generating output pulses with frequency f ≤ 1 Hz
operating communication (local or remote) with the device for 2 min per day
service communication (local or remote) with the device for 5 min per week
firmware update (locally or remotely) once a year

Under these conditions, the lifetime of the batteries supplied for typical ELCOR and ELCOR
plus
configurations is shown below:

) Temperature range when lithium battery power supply B-03, B-03D is used.
21
) Temperature range when alkaline battery power supply B-03A is used.
In special cases, the
B-03A
alkaline battery can be used to power the ELCOR
plus
and ELCOR
plus
indexer
. When using this battery, an internal modem cannot be
used in the device.
If the battery capacity drops to 10% before the expected discharge, the device will
alert you of the need to replace the battery (error message
E9
, see Table 14).
