HP Smart Array RAID Controller Battery

The NShi MC96 is a 7.2V 8Wh 1100mAh replacement battery designed for HP Smart Array P440AR, P840AR, P440 and P840 RAID controller modules. It restores cache backup power so the controller can preserve write data during unexpected power loss.

Replaces OEM Part Numbers 750450-001 and HSTNN-IS6A

This unit substitutes for the original HP batteries listed under part numbers such as 750450-001, 727260-002, HSTNN-IS6A and HSTNS-BB02. The upgrade is worth it when the existing battery no longer holds charge and the controller reports a cache backup failure.

For Administrators Maintaining HP Smart Storage

It suits IT staff who need a direct drop-in cell matching the MC96 form factor and connector. Buyers who require a different voltage, capacity or physical layout for non-Smart Array hardware should look at something else.
