4-Cell 14.8V Lithium-Ion Replacement

This FOCUSTEC battery replaces HP spare numbers such as 807956-001 and 807957-001 in Pavilion 14 and 15 series laptops. It delivers 2600mAh capacity at 38Wh using four lithium-ion cells. Buyers must verify their original battery number or regulatory code before ordering.

Upgrade From Worn 3-Cell Packs

A jump from a degraded three-cell unit restores full voltage and roughly one-third more watt-hours. The improvement matters when the original battery no longer holds charge through a typical work session. Users whose machines already shipped with a four-cell 38Wh pack will not gain additional runtime.

Limited By Proprietary Connector && Firmware

The pack fits only HP models that accept the HS03 or HS04 form factor and recognise the matching regulatory identifiers. It cannot be used in laptops requiring a different pin layout, higher cell count or vendor-locked firmware authentication. Compatibility must be confirmed against the exact spare or battery number printed on the old unit.
