Compatible RAID Controller Battery

This replacement battery fits HP Smart Array P440, P440AR, P840 and P840AR RAID controllers. It supplies 7.2V and 8Wh capacity using lithium-ion cells. The unit matches part numbers MC96, MC96G9, 750450-001, 786761-001, 815983-001 and HSTNN-IS6A. It is designed for cache backup in supported Smart Storage controllers.

Cache Backup Duration Limits

The 1100mAh capacity determines how long write cache data is preserved during a power loss. Actual hold-up time depends on the controller model, cache size and system load. The battery connects only to the designated cache module socket on the listed controllers. No other interface or charging method is supported by this part.

Verify Controller Model Before Ordering

Confirm the exact Smart Array controller model installed in your server matches the supported list above. Check that the existing battery connector and mounting orientation correspond to the original part. Ensure the server firmware recognises the battery for cache protection functions. This battery does not fit controllers outside the specified P440 and P840 series.

Questions about this item

Which part numbers does this 7.2 V 8 Wh battery replace?

It replaces MC96, MC96G9, 750450-001, 786761-001, 815983-001 and HSTNN-IS6A in HP Smart Array P840AR, P440AR, P840 and P440 controllers.

What runtime can I expect from the 1100 mAh capacity inside a RAID controller?

The 8 Wh pack powers the controller cache during a power loss long enough to flush data to disk; actual hold-up time depends on the controller load.

What connector standard does the MC96G9 use and what does it limit?

The pack uses the proprietary HP Smart Storage battery connector, which limits use to the listed P840AR, P440AR, P840 and P440 RAID controllers.
