Replacement Battery for HP Spectre x360 15

The KB06XL lithium-ion battery delivers 11.55V and 79.2Wh capacity for HP Spectre x360 15 series laptops. It replaces original part numbers including HSTNN-DB7R and TPN-Q179. The unit is new from the manufacturer with integrated smart-chip circuitry.

Verify Model and Part Number Before Ordering

Confirm your laptop model appears in the supported list such as 15-BL012DX or 15T-BL100. Cross-reference the existing battery part number against KB06XL or 902499-855 to ensure correct fit. Check that the voltage rating matches 11.55V.

Smart Chip Enables Accurate Reporting

The onboard smart chip communicates charge status to the system for correct percentage readouts. If the battery is not recognised at first install, reseat the connector and cycle the charge down to 10 percent. This process calibrates the fuel gauge for reliable runtime estimates.

Questions about this item

Does the KB06XL battery ship with any tools or cables, or do I need to buy a screwdriver kit separately?

The package contains the 11.55V 79.2Wh Li-ion battery only; a compatible screwdriver set for the HP Spectre x360 15 chassis must be sourced separately.

My HP Spectre x360 15-bl012dx shows part number 902499-855 on the old cell — is KB06XL the correct match?

Yes, KB06XL replaces part numbers 902499-855, 902499-856, 902401-2C1, HSTNN-DB7R and TPN-Q179 used in the 15-bl012dx and related 15-bl0xx models.

What does the 79.2Wh rating mean for daily runtime on a 15-bl0xx series laptop?

The 79.2Wh capacity restores the original factory runtime; expect comparable hours per charge to when the notebook was new, depending on screen brightness and workload.
