DS4700 FAST T BATTERY

The IBM DS4700 FAST T battery, MPN 41Y0679-RFB, is a replacement module for IBM DS4700 storage arrays. It provides backup power for cache protection and controlled shutdown when normal power is interrupted, supporting the array’s battery-backed functions.

The distributor identifies it as a rechargeable lithium-ion industry battery. It replaces article 41Y0679, a reference that helps distinguish this module from other battery assemblies. Its listed dimensions are 150 mm long, 100 mm wide and 50 mm high.

For array maintenance, this module restores battery support for cache protection and shutdown processes. It is intended for IBM DS4700 storage systems that use the FAST T battery assembly. This is a component for enterprise storage equipment, not a notebook battery or general-purpose portable power source.
