Compatible HP Envy Models

This 4-cell lithium-ion battery replaces the original KC04XL pack for HP Envy 13-AH, 13-AQ, X360 13-AG and X360 13-AR series laptops. It delivers 15.4V and 53.2WHR capacity to restore factory runtime. The GreenTech unit is brand new and carries CE, FCC and RoHS safety certifications.

Installation Notes

Replacing the pack requires opening the bottom case and disconnecting the internal cable; most Envy 13 models use a multi-screw chassis that can strip if the wrong driver size is used. The connector keying matches the OEM part, but forcing it bent pins in a small number of field reports.

Capacity Decides Fit

The 3454mAh rating at 15.4V equals 53.2WHR; if your service tag lists a different watt-hour value this pack will not seat correctly or the firmware will reject it. Buyers needing a higher-capacity option cannot use this model.

Questions about this item

How do I confirm the 15.4V 53.2WHR battery is working after installation?

The laptop should power on without the charger, show the correct 53.2WHR capacity in the system battery report, and hold charge through normal use with stable current and low self-discharge.

What comes in the box and do I need any extra parts to fit the KC04XL?

The box contains the 4-cell 3454mAh replacement battery only; no tools, screws or cables are included, and the original laptop hardware is reused for installation.

Which GreenTech model matches my HP ENVY 13-ah0010NR — KC04XL or L08496-855?

Both part numbers refer to the same 15.4V 4-cell battery; either KC04XL or L08496-855 fits the ENVY 13-ah0010NR and the other listed ENVY 13-AH, 13-AQ and X360 13-AG models.
