NShi LK03XL 55.8Wh replacement battery

This 11.55V lithium-polymer pack is built for HP Envy X360 Convertible 15-inch and 17-inch models listed in the compatibility data. It suits owners whose original cell has lost runtime or no longer holds charge. Buyers needing a different voltage or form factor should verify their part number before ordering.

3-cell 55.8Wh capacity and runtime

The three-cell design delivers 55.8Wh at 11.55V, matching the factory specification for the supported Envy X360 series. It will restore typical mixed-use runtime for web browsing, document work and media playback. Heavy workloads such as sustained rendering or gaming will drain the pack more quickly and may require more frequent recharging.

Questions about this item

Will the LK03XL 11.55V 55.8Wh battery fit my HP Envy x360 15-bp112dx without any chassis modifications?

Yes, the LK03XL is listed as a direct replacement for the 15-bp112dx and shares the original form factor, so it seats in the existing battery bay without modifications.

How can I verify the LK03XL is delivering the rated 11.55V and 55.8Wh after installation?

Check the battery information in the UEFI BIOS or the HP Support Assistant; both report the design voltage and full-charge capacity, confirming the pack is recognised at 11.55V and 55.8Wh.

Does the LK03XL package include the Torx T5 and Phillips #0 screwdrivers needed to open the Envy x360 bottom cover?

No, the box contains only the 3-cell lithium-polymer battery; the T5 and #0 drivers must be sourced separately.
