Replacement battery for HP Envy X360 convertibles

This 55.8Wh lithium-ion unit replaces part numbers LK03XL, L09281-855 and 916814-855 across the 15m-cn, 15-bp, 15-bq, 15-cp, 17m-ae, 17-bw and 17-ce model families. It delivers 11.55V and 4835mAh from new cells with an integrated smart chip. The pack is black and weighs 320 grams.

Voltage and capacity limits for this pack

The battery operates at 11.55V and stores 55.8Wh, so it cannot supply the 20V required by the laptop's AC adapter. Runtime depends on the host system's power draw and the charge controller's firmware calibration. No higher-capacity version of this exact form factor is listed in the compatibility data.

Verify the exact model code before ordering

Open Windows System Information (msinfo32) and confirm the System Model matches one of the listed variants such as 15m-cn0011dx, 17m-ae111dx or 15-bp112dx. Cross-check the old battery's part-number sticker against the replace list including HSTNN-LB7U, TPN-W127 or L09281-855. Mismatched codes will prevent proper fit and communication.
