Replacement battery for HP Envy and Pavilion x360

This lithium-polymer pack is built for HP Envy 15 and Pavilion 13 x360 convertibles listed in the compatibility data. It restores mobile power for owners whose original cell no longer holds a charge. The 3.75 Ah capacity matches the factory specification for the supported models. Buyers with other laptop lines will need a different part.

Sustained discharge at rated capacity

The cell delivers its rated 3.75 Ah steadily across a normal work session rather than only in short bursts. Internal resistance stays stable so voltage does not collapse under typical productivity loads. Runtime scales with the workload of the host machine. Systems drawing significantly more current than the original design target will see reduced endurance.

Thermals noise and power draw in normal use

Lithium-polymer chemistry runs cool during everyday charging and discharging. No moving parts means silent operation inside the chassis. Power draw follows the laptop's own management profile without adding measurable overhead. The pack does not require active cooling or produce audible noise.

Questions about this item

Does the 3.75 Ah Li-Polymer cell run hot during all-day use?

The Li-Polymer chemistry typically stays cooler than older cylindrical cells, so the battery remains within normal operating temperature during continuous use.

Must my HP Envy or Pavilion model appear in the listed part numbers such as 15-U011DX or 13-A001NF for this battery to fit?

Yes, the battery is built for the exact models shown — 15-U011DX, ENVY 15-U001XX, Pavilion 13-A001NF and the other listed part numbers — so your laptop must match one of them.

Will this DS-CS-HPX361NB work alongside the original HP charger I already own?

The battery charges through the laptop's standard charging circuit, so your existing HP AC adapter will charge it normally.
