For owners of the listed HP models needing

This unit matches the voltage, capacity and form factor of the factory battery, so it fits the same bay and connects to the same header without modification. Buyers whose laptops fall outside the stated EliteBook and ZBook series should verify their part number before ordering, as the connector and physical dimensions differ across other HP lines.

56Wh capacity at 11.55V across three cells

The energy rating of 56Wh and the 11.55V nominal voltage are the decisive figures; they must match the original battery label exactly for the notebook to charge and report capacity correctly. If the original pack shows a different watt-hour value or voltage, this replacement will not be compatible.
