Replacement Battery for HP Envy Series

This new GreenTech battery replaces OEM part LK03XL and compatible variants across the HP Envy 17-AE, 17-BW, 17-CE and Envy x360 15-BP, 15-CN, 15-CP families. It is built for owners whose original pack no longer holds a useful charge and who need a direct drop-in replacement with the same physical fit and connector layout. The three-cell lithium-ion design matches the factory form factor for straightforward installation.

11.55 V Operating Voltage

The single specification that determines fit is the 11.55 V output. Your laptop’s charging circuit expects this exact voltage; a pack rated differently will not charge correctly or may trigger protection faults. Verify that the original battery label shows 11.55 V before ordering, as some similar-looking Envy models use other voltages.

56 Whr Capacity and Runtime

At 56 Whr and 4848 mAh the pack restores the runtime the laptop delivered when new, typically covering a full workday of mixed office tasks and media playback. Heavy workloads such as sustained video rendering or gaming will drain the cells faster, so users who regularly push the CPU and GPU should keep the charger handy for longer sessions.

Questions about this item

How long will the 56WHR rating actually run my laptop?

The 56WHR capacity translates to roughly 4848mAh at 11.55V, so real-world runtime depends on your model's power draw; lighter workloads on an ENVY 17 or x360 15 will yield several hours.

What connector standard does the LK03XL use and does it limit charging speed?

It uses the original HP internal battery connector for the listed ENVY 17-AE, 17-BW, 17-CE and x360 15-BP series, so charging is governed by the laptop's own power-management circuitry.

Will this 3-cell pack physically fit my ENVY 17-AE chassis?

Yes, the LK03XL is built to the same form factor as OEM part numbers 916814-855 and HSTNN-UB70, matching the battery bay dimensions for all listed 17-inch and 15-inch ENVY models.
