Product information

Description

Replacement cache backup battery IBM SS DS3000 39R6520-RFB 3.6V 1000mAh is a dedicated backup power unit designed for IBM System Storage DS3000 series controllers. Rated at 3.6 volts and 1000 mAh, this cache battery provides short-term power to preserve cached data and allow controlled shutdown of cache functions during mains power loss. The unit is intended as a direct replacement for the original 39R6520-RFB module and is compatible with supported DS3000 storage controller assemblies to maintain data integrity and reduce the risk of data loss in enterprise storage environments.

Advantages

This IBM-branded cache battery offers a compact form factor and the specified 3.6 V / 1000 mAh rating that matches OEM requirements for DS3000 systems. By supplying temporary power to the controller cache, it helps ensure cached write operations are committed or safely held until normal power is restored. The battery’s compatibility with the 39R6520-RFB reference and its OEM-grade electrical characteristics make it suitable for use as a reliable service replacement in maintenance and repair scenarios.

How to use
