Replacement Battery for HP Envy X360 Convertibles

This 3-cell lithium-polymer battery delivers 11.55V and 52.5Wh capacity for compatible HP Envy X360 15-inch and 17-inch convertible models. It replaces part numbers including LK03XL, L09281-855, 916814-855 and 916368-421. The package includes the battery, two screwdrivers and an instruction sheet for user installation.

Sustained Power Delivery

The 2600 mAh cell configuration maintains a steady 11.55V output during extended sessions, supporting consistent run-time for convertible workloads. Rated at 52.5Wh, it is designed to hold charge across repeated cycles without rapid voltage sag. The chemistry is built for daily recharge routines rather than occasional top-ups.

Build and Daily Handling

The black pack measures 14.33in W x 12.83in H x 9.06in D and weighs 8 ounces, fitting the internal bay of the listed Envy X360 series. Included screwdrivers match the chassis fasteners so no extra tools are required. Buyers needing a higher-wattage pack or a different voltage for non-listed models cannot use this unit.

Questions about this item

How much heat does the 11.55 V 52.5 Wh lithium-polymer pack generate during a full day of use?

The battery itself produces minimal heat; any warmth comes from the laptop's charging circuit and workload rather than the 3-cell pack.

Which screwdriver bits are required to swap the LK03XL in an HP Envy X360 15m-bp112dx?

The box includes two screwdrivers matched to the case screws used on compatible Envy X360 models.

Will the LK03XL fit a legacy HP Envy X360 15-bp0xx that originally shipped with a 31 Wh battery?

Yes, the 52.5 Wh LK03XL replaces the lower-capacity pack and shares the same 11.55 V voltage and connector.
