2.4.14 Battery
The lithium battery (3 V, 950 mAh) buffers the internal real-time clock (RTC). It is located on the back of the Panel
PC. The battery is installed in a battery holder, making it very easy to replace.
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 SRAM interface option has been installed, this lifespan is reduced to 2½ years. The battery
has a limited service life and should be replaced regularly (after the specified service life at the latest).

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 load (approximately 1 second)
and then evaluated. Once determined, the battery status is displayed in BIOS (Advanced - OEM Features - System
board features - Voltage values) and in the B&R Control Center (ADI driver); it can also be read in a customer
application using the ADI library.

Description
N/A
The hardware or firmware being used is too old and does not support reading the battery status.
GOOD
Data buffering is intact.
BAD
From the point when battery capacity is recognized as insufficient (BAD), data buffering is intact for approximately another 500
hours.
From the point when battery capacity is recognized as insufficient, data buffering is intact for approximately another
500 hours. When replacing the battery, data is buffered for approximately 10 minutes by a gold leaf capacitor.
