Not for other voltages or form factors

Buyers whose laptop requires a different voltage or a different physical pack cannot use this unit. It is not suitable for models outside the listed HP Envy M6-K and 14-K series. Anyone needing a higher or lower watt-hour rating should look elsewhere.

11.1V 50Wh three-cell specification

The battery operates at 11.1V and stores 50Wh across three lithium-ion cells. This voltage and capacity combination determines whether it matches the original hardware. Verify the voltage and watt-hour rating on the old battery before ordering.

Questions about this item

Which HP laptop models accept this PX03XL 50Wh 11.1V battery as a direct replacement?

It replaces part numbers PX03XL, 715050-001, 714762-421, 714762-422, 714762-1C1, 714762-2C1, HSTNN-LB4P, TPN-C109, TPN-C110 and TPN-C111 in HP ENVY Touchsmart M6-K, Sleekbook and 14-K series laptops.

Will the three-cell 11.1V layout fit the same bay and connector used by the original HP battery in my Envy Touchsmart 14-k000?

Yes, the 3-cell 11.1V design matches the original form factor and connector for the listed 14-k000 and 14-k100 models, so it seats in the existing bay without modification.

How can I confirm the battery is delivering its rated 50Wh capacity after installation?

Charge it fully, then check the reported design capacity in the OS battery report or BIOS; it should read 50Wh, and the battery should hold charge consistent with the 11.1V 3-cell specification.
