Removing and replacing the system battery

If the compute module no longer automatically displays the correct date and time, replace the system battery. The system battery provides power to the real-time clock. Under normal use, battery life is 5–10 years.

  • Do not attempt to recharge the battery.
  • Do not expose the battery to temperatures higher than 60°C (140°F).
  • Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
  • Replace only with the spare designated for this product.

    IMPORTANT: Replacing the system board battery resets the system ROM to its default configuration. After replacing the battery, use BIOS/Platform Configuration (RBSU) in the UEFI System Utilities to reconfigure the system.

To replace the component, reverse the removal procedure.
