R660xs RAID Battery

Last Updated : Aug 18, 2025 |

With the introduction of the Dell R660xs, the RAID battery is no longer a separate orderable entity. In the event of a failure of the RAID battery, you need to order a replacement RAID card.

Note:

ASP R6.0.0.1 or later includes perccli command support to enable users to query RAID battery health. For more information, see Chapter 31: Dell R660xs and R640 perccli debugging.

  • Slow server write performance.

  • Slow or failed software upgrades.

  • Error displayed on power up screen or LCD panel when server is powered on.

  • Avaya's application or iDRAC alarming has indicated a RAID battery failure.
