727260-002 is the HPE model number for 96W Megacell Smart Storage Battery with 145mm Cable. If you have pulled a battery from a Gen9 chassis and are reading the label to find the matching HPE number, this is the model-level identifier stamped on the unit itself rather than the number used on a boxed option kit. The battery is a Smart Storage Battery rated at 96W Megacell and ships with a 145mm (5.7 inch) power cable. It is used in HPE ProLiant Gen9 servers including the DL20, DL60, DL80, ML110, DL120, ML150, DL160, DL180, ML350, DL380, DL388 and DL560.

FREQUENTLY ASKED QUESTIONS ABOUT 727260-002
What is the difference between 727260-002, 727258-B21 and 750450-001?
They identify the same physical battery. 727260-002, this page, is a model number: the identifier carried on the unit and used when cross-referencing a part you already hold. 727258-B21 is the option part number, the number HPE assigns to the orderable kit. 750450-001 is a spare part number, used for service replacement. This family also includes one further OEM drive model and two additional spare part numbers, all listed in the cross-reference block on this page.
What does the 145mm cable length mean for my install?
The battery ships with a 145mm (5.7 inch) power cable, which determines how far the battery can sit from its board connector inside the chassis. HPE supplies different cable lengths for different Gen9 chassis layouts, so confirm the length called out for your server before fitting. If your chassis routing was built around a 145mm run, 727260-002 is the matching configuration.
Which servers does 727260-002 support?
This 96W Megacell Smart Storage Battery is listed for HPE ProLiant Gen9 servers: DL20 Gen9, DL60 Gen9, DL80 Gen9, ML110 Gen9, DL120 Gen9, ML150 Gen9, DL160 Gen9, DL180 Gen9, ML350 Gen9, DL380 Gen9, DL388 Gen9 and DL560 Gen9. That list spans both rack and tower models. Servers outside the Gen9 ProLiant range are not covered by the compatibility data for this part.
I only have an OEM model number from the label. How do I map it to an HPE number?
An OEM model number is the identifier applied by the manufacturer that built the unit, and it will not always match the HPE-facing numbers. Use the cross-reference block on this page: it shows the option, model, spare and OEM identifiers that all describe this same 96W Megacell Smart Storage Battery, so you can move from whichever number you have in hand to the one your procurement or service process requires.
