Direct replacement for HP Envy X360

The PISKEKAT LK03XL is a new laptop battery built to replace original part numbers including LK03XL, 916814-855 and L09281-855. It fits HP Envy X360 15-bp, 15-bq and 15-cn convertibles as well as Envy 17-ae, 17-bw and 17-ce clamshell models. Install it to restore mobile power without adapter changes.

Fits existing chassis and connector

The cell pack uses the factory connector and mounting points, so it slots into the same bay and plugs into the same motherboard header. No cable routing, BIOS updates or chassis modifications are required. The design frees the owner from tethered outlet dependence while preserving the original form factor.

Restores factory runtime for listed models

Capacity matches the OEM specification for the compatible Envy X360 15-inch and 17-inch series, delivering the same full-charge endurance the laptop shipped with. It will not extend runtime beyond the original design limit, and it does not support models outside the listed part-number range.

The LK03XL matches the original voltage and chemistry, so thermal output under sustained load is comparable to the factory pack.
