Check your part number first

Verify that your original battery carries one of the listed part numbers such as LK03XL, L09281-855, 916814-855 or HSTNN-LB7U before ordering. This unit is not suitable for HP Envy X360 models outside the specified 15-inch and 17-inch series or for laptops requiring a different voltage or cell count. Buyers needing a higher capacity pack or a different form factor should look elsewhere.

Build and daily handling

The black casing uses standard lithium-ion cells in a 3-cell layout matching the original dimensions for a secure fit inside the chassis. Supplied screwdrivers let you remove the bottom cover and swap the pack without sourcing extra tools. Once installed, the battery connects to the existing motherboard header, restoring portable power with no adapter changes required.
