✅ Confirmed Compatibility

Compatibility is based on the installed RAID controller rather than the server model alone. The system must be configured with a supported PERC 5/E or PERC 6/E external controller and the correct battery cable, molding and mounting hardware.

⚙️ Fit Notes

• Confirm the printed battery part number, connector, molded housing and mounting arrangement before ordering.
• This battery family is intended primarily for PERC 5/E and PERC 6/E external controllers.
• Do not substitute an internal-controller battery solely because it has the same 3.7V and 7Wh ratings. Internal PERC 5/i and 6/i batteries such as NU209, U8735, FR345, FR463, P9110, XJ547 and UF302 can use different exterior molding or mounting arrangements.
• The battery cable is not included. Cable length and routing vary by controller and chassis.
• Some PERC 5/E assemblies specify cable U9203. Match the original cable part number whenever possible.
• The linked YH927 and RY631 cables should only be used when their connector, pinout and length match the original installation.
• After installation, allow the battery to charge and verify its status through the controller-management utility.
• The controller may temporarily disable write-back caching until the replacement battery completes its initial charge, health verification or learn cycle.
• Shut down the system, disconnect power and follow proper electrostatic-discharge precautions before servicing the controller.
• Recycle the removed lithium-ion battery through an approved battery-recycling facility.
