Backup battery
The lithium battery on the mainboard powers the real-time clock (RTC)
in the absence of power. When the battery starts to weaken, it loses
voltage, and the server settings stored in CMOS RAM in the RTC (for
example, the date and time) might be incorrect.
For a list of approved replacement batteries, contact your customer
service representative or dealer.
Warning! Danger of explosion if battery is incorrectly
replaced. Replace with only the same or equivalent type
recommended by the manufacturer. Dispose of used
batteries according to the manufacturer's instructions.
