System Battery
The HP ProLiant server uses nonvolatile memory that requires a battery to retain system
information when power is removed. The battery, a 3 V 200-mAh internal lithium battery, is
located on the system board (BT1).

If the server no longer automatically displays the correct date and time, the system battery
that provides power to the real-time clock may need to be replaced. Under normal use, battery
life is 5 to 10 years.

•
Replace the battery with the same type as the battery recommended by HP. Use of
another battery may present a risk of fire or explosion.
•
A risk of fire and chemical burn exists if the battery is not handled properly. Do not
disassemble, crush, puncture, or short external contacts, or expose the battery to
temperatures higher than 60
°
C (140
°

•
Do not dispose of used battery in water or fire. Dispose of used batteries according
to manufacturer's instructions.
CAUTION: Loss of BIOS settings occurs when the battery is removed. BIOS settings must be
reconfigured whenever the battery is replaced.
