14.8V 2600mAh replacement battery for HP 14

This new lithium-ion pack delivers 14.8 volts and 2600 milliampere-hours across four cells. It replaces HP part numbers HS03, HS04, 807956-001 and 807957-001. The unit fits HP 14, 14g, 14q, 15, 15g, 15q and 240, 245, 246, 250, 255, 256 G4 notebooks listed in the compatibility data. Black housing matches the original colour.

Simple swap with basic tools

Most listed models use a bottom-access battery bay secured by one or two screws; removing the old pack and inserting the new one takes minutes. The connector is keyed, so it only fits one way — forcing it can bend pins. If the laptop does not recognise the battery after fitting, reseat the connector and allow a full charge cycle before judging capacity.

Verify exact model and part number before ordering

HP 14 and 15 families share similar chassis but use different battery part numbers across sub-series. Match the part number on your existing battery — 807956-001, 807957-001, HSTNN-LB6U, HSTNN-LB6V, HSTNN-PB6T, HSTNN-DB7I, TPN-I120, 807611-421 or 807612-421 — to this SKU. Buyers needing a different voltage, cell count or form factor cannot use this pack.

Questions about this item

How do I verify the 14.8V 2600mAh battery is working after fitting it to my HP 15-ay009dx?

Insert the battery, power on the notebook and confirm the operating system reports a charging state; the firmware should show the correct voltage and capacity within a few minutes.

What comes in the box with the HSTNN-LB6U and do I need any extra parts for my HP 14-an012nr?

The package contains the 4-cell lithium-ion battery only; no cables, screws or tools are included, so reuse the original hardware from the old pack.

My HP 250 G4 lists both HSTNN-LB6U and HSTNN-LB6V — which one should I choose?

Both part numbers are listed as direct replacements; the HSTNN-LB6U matches the 807956-001 spare and fits the same 14.8V 2600mAh specification.
