FREQUENTLY ASKED QUESTIONS ABOUT 727260-001
What is the difference between 727260-001, 727258-B21 and 750450-001?
They identify the same physical battery at different levels. 727260-001, this page, is a model number, which is the identifier tied to the manufactured unit itself. 727258-B21 is the option part number, the number HPE used to sell the item as an orderable option. 750450-001 is a spare part number, used for service replacement. This family also includes one further OEM drive model number and two additional spare part numbers, all listed in the cross-reference block on this page.
Which servers does 727260-001 support?
This battery is listed for HPE ProLiant Gen9 servers: DL20 Gen9, DL60 Gen9, DL80 Gen9, DL120 Gen9, DL160 Gen9, DL180 Gen9, DL380 Gen9, DL388 Gen9, DL560 Gen9, and the tower models ML110 Gen9, ML150 Gen9 and ML350 Gen9. Confirm the cable length required by your chassis before ordering, as this unit ships with the 145mm cable.
What does the 145mm cable specification mean here?
The 145mm (5.7 inch) power cable is the cable supplied with this battery and connects it to the system board power header. Cable length varies across Smart Storage Battery variants because the battery mounting point differs by chassis. When cross-referencing an OEM number to an HPE number, verify that both the 96W Megacell rating and the 145mm cable length match, not the wattage alone.
What is the difference between an assembly part number and an OEM model number?
An assembly part number identifies a complete built unit as HPE assembles and ships it, including any attached cabling. An OEM model number identifies the product as designated by the manufacturer that builds it, and is the number you are most likely to see printed on the hardware itself. Both can point to the same physical battery, which is why cross-referencing between the two is often necessary.
