HP 96W Smart Storage Battery
The HP 727258-B21 is a 96W rechargeable battery module designed for HPE ProLiant DL, ML and SL servers. It protects write-cache data on Smart Array controllers during unexpected power loss. This accessory is intended for administrators maintaining compatible HPE server infrastructure.
Fits supported HPE server chassis
The unit ships with a 145mm cable for connection to the controller. Its proprietary form factor measures 2.3in high, 7.5in wide and 9.5in deep, weighing approximately 1lb. It installs internally to preserve cache without occupying drive bays or PCIe slots. Servers outside the DL/ML/SL families cannot use this battery.
Passive operation with no added noise
The battery operates without fans, adding no acoustic load to the server. It draws power only during recharge cycles after a discharge event. Thermal output is negligible under normal float conditions. No active cooling provision is required for the module itself.

What heat or noise does the unit add when it runs continuously in a server?
The sealed battery has no fan or moving parts, so it generates no audible noise and contributes only passive heat within the chassis.
