What this battery replaces

This 50Wh 11.1V Li-polymer unit replaces the PX03XL and HSTNN-IB4P packs used in several HP ENVY 14 Sleekbook models. It is a brand-new replacement part, not an upgrade or a different chemistry. The black housing matches the original appearance.

Check your exact model first

Verify that your laptop carries one of the TPN-C109, TPN-C110 or TPN-C111 board codes before ordering. The same ENVY 14 or ENVY M6 marketing name can hide different internal revisions that take incompatible packs. Cross-reference the part number printed on your old battery against the list above.

Daily fit and finish

The pack uses the same connector layout and mounting points as the factory unit, so it seats without forcing cables or screws. Li-polymer construction keeps the profile slim while delivering the rated 4350mAh capacity. No extra adapters or firmware steps are required after installation.

Questions about this item

Does the POWER-FENG 50Wh battery ship with any cables or tools, or do I need to buy them separately?

The listing covers the battery unit only; no cables, screws or opening tools are included, so you will need to supply your own if the laptop requires them.

My HP ENVY model shows TPN-C110 on the service tag — is this the correct 50Wh 11.1V replacement?

Yes, the battery replaces part numbers PX03XL and HSTNN-IB4P and is listed as compatible with TPN-C110 among other ENVY 14 Sleekbook and M6 series models.

How long will the 50Wh 4350mAh capacity actually run my ENVY 14 Sleekbook under normal office work?

At 11.1V and 50Wh the pack stores the same energy as the original PX03XL; real-world runtime depends on screen brightness, CPU load and battery health, but it matches the factory-rated capacity.
