3-cell 55.8 Wh replacement battery

This 2-Power LK03XL unit is a 3-cell lithium-ion battery rated at 55.8 Wh and 11.55 V. It is built as a direct replacement for compatible HP Envy x360 convertible notebooks in the 15-inch and 17-inch series. The pack ships with two screwdrivers and an instruction sheet for user installation.

500-cycle service life under normal use

The manufacturer rates the cell chemistry for up to 500 charge cycles over the battery's lifespan. Capacity will gradually decline with repeated deep discharges and high-temperature exposure, so runtime in later years will be lower than when new.

11.55 V nominal voltage constraint

The pack operates at a fixed 11.55 V nominal voltage; the laptop's charging circuit must match this value exactly. Using the battery in a system that expects a different cell count or voltage will prevent charging or cause the firmware to reject the pack.

Questions about this item

Does the 55.8 Wh, 3-cell LK03XL battery generate noticeable heat during all-day use?

The lithium-ion pack is rated at 11.55 V and 55.8 Wh; under normal loads it runs at typical laptop-battery temperatures and does not require active cooling.

Must the HP Envy x360 already have a working 20 V, 100 W AC adapter for this battery to charge?

Yes, the replacement cell charges from the laptop’s own 20 V, 100 W power supply, which must be present and functional.

Will this LK03XL pack fit the original battery bay on a 15-bp or 17-ae series Envy without modification?

It matches the OEM dimensions and connector for the listed 15-bp, 15-bq, 15-cn, 17-ae, 17-bw and 17-ce models, so no chassis changes are needed.
