The pack delivers 11.4 volts and 48 watt-hours from four lithium-polymer cells. This voltage and capacity combination is the single figure that determines whether the battery will power the listed notebooks correctly. Systems requiring a different voltage or watt-hour rating will not operate with this unit.

Two screwdrivers included for installation

A pair of screwdrivers ships in the box so the battery can be swapped without sourcing tools separately. The bundled drivers cover the fasteners used on the compatible EliteBook and ZBook chassis. No software, calibration utilities or additional cables are supplied.

Questions about this item

What does the 48 Wh capacity mean for daily runtime on my EliteBook?

The 48 Wh rating stores enough energy for several hours of typical office work; actual time varies with screen brightness, workload and power settings.

How does the 11.4 V voltage interact with the laptop's charging circuit?

The 11.4 V matches the original HP specification, so the notebook's built-in controller manages charge and discharge without modification.

What physical fit should I expect when installing this 4-cell pack in a ZBook 15u G3?

The pack uses the same form factor and screw positions as the original CS03XL, and two screwdrivers are included for the swap.
