Due to a slip of the keyboard we've accidently ordered the wrong batteries for our HP servers. Consequently I have now got three HP 383280-B21 kits (link) and three 24" leads for the same.

The battery's HP part number is 384573-001 and the HP Spares number is 398648-001. The lead Kit number is 417836-B21 (link).

They are for the Smart Array P400 series and fit onto the memory module DIMM.

The are brand new and boxed (I opened one before I realised it was the wrong type though) and I'm looking to recoup some of the cost since I can't return them as it was a special order. Each battery pack cost just short of £100 and the leads were around £25 each.
