2.6.13 Battery
The lithium battery (3 V, 950 mAh) buffers the internal real-time clock (RTC) as well as the
individually saved BIOS settings and is located behind the black cover. The buffer duration of the
battery is at least 2½ years (at 50°C, 8.5 µA current requirements of the supplied components
and a self discharge of 40%). The battery is subject to wear and should be replaced regularly (at
least following the specified lifespan).
Battery status evaluation
The battery status is evaluated immediately following start-up of the device and is subsequently
checked by the system every 24 hours. The battery is subjected to a brief load (1 second) during
the measurement and then evaluated. The evaluated battery status is displayed in the BIOS
Setup pages (under Advanced - Main board monitor) and in the B&R Control Center (ADI driver),
but can also be read in a customer application via the ADI Library.
