2.4.6 Battery
The lithium battery (3 V, 950 mAh) buffers both the internal real-time clock (RTC) as well as data stored in the
SRAM of interface cards. It is located behind the black cover on the front of the device. The battery's buffer lifespan
is at least 4 years (at 50°C, 8.5 μA for the components being supplied and a self-discharge of 40%; if an interface
board with SRAM is installed, then the lifespan is reduced to 2½ years). The battery has a limited lifespan and
should be replaced regularly (after the specified service life at the latest).

Battery status evaluation
The status of the battery is determined immediately after the device is started and subsequently checked by the
system every 24 hours. During this measurement, the battery is subjected to a brief (approximately 1 second) load
and then evaluated. Once determined, the battery status is displayed in BIOS (under OEM Features - CPU Board
Features - CPU Board Monitor) and in the B&R Control Center (ADI driver); it can also be read in a customer
application using the ADI library.
Battery status
Meaning
N/A
The hardware or firmware being used is too old and does not support reading the battery status.
GOOD
Data buffering is provided.
BAD
Data buffering is provided for approximately another 500 hours from the point when battery capacity is recognized as insufficient
(BAD).
Table 11: Meaning of the battery status
Data buffering is provided for approximately another 500 hours from the point when battery capacity is recognized
as insufficient. When replacing the battery, data is buffered for approximately 10 minutes by a gold leaf capacitor.
