Compatible 56Wh replacement battery

This 56Wh lithium-polymer battery replaces part numbers PK03XL, 789116-005, 788237-2C3 and HSTNN-DB6S. It fits HP Spectre X360 13-4000 and 13-4100 series models along with select Envy X360 13-y and 15-ay units. The pack is brand new and rated for 300 to 500 charge cycles. Check the original battery part number before ordering.

Voltage and capacity limits

The cell delivers 11.4V and 56Wh in a 3-cell configuration. That voltage is fixed by the laptop's charging circuit, so the pack cannot be used in systems that require a different nominal voltage. Capacity determines runtime; 56Wh is the exact figure the original design expects. No higher-capacity alternative exists in this form factor.

Verify the part number match

The single specification that decides fit is the part number printed on the original battery. The laptop model list is long, but only a PK03XL or 789116-005 label guarantees the correct connector, shape and firmware handshake. If the sticker shows a different code, this battery will not work.
