Direct replacement for HP Spectre x360 15-bl series

This 79.2Wh lithium-polymer battery matches the original KB06XL specification at 11.55V and 6860mAh. It fits the Spectre x360 15-bl models including 15-bl002xx, 15-bl012DX, 15-bl018CA and the TPN-Q179 platform. The unit arrives new and ready to install.

Simple internal swap with connector alignment

Installation requires opening the chassis and disconnecting the old pack before seating the new one into the same bay. The plug orientation is fixed, so reversing it is the only common mistake. No soldering or firmware steps are involved; the system recognises the battery on first boot.

79.2Wh capacity supports typical mobile workloads

The 6860mAh cell delivers a full day of office tasks, web browsing and video playback on a single charge. Heavy GPU loads or sustained high brightness will drain it faster, and the pack cannot exceed its rated watt-hour limit. Runtime scales with the power profile you choose in Windows.

Questions about this item

How do I confirm the 11.55V 79.2Wh battery is charging correctly after installation?

The laptop battery indicator should display a charging animation; HP Support Assistant or the built-in BIOS diagnostics can verify the 6860mAh capacity and voltage are recognised.

What comes in the box with the KB06XL replacement and do I need any extra parts?

The package contains the 11.55V Li-polymer battery only; no tools, screws or AC adapter are included, so reuse the original fixings from the HP Spectre x360 15.

Which KB06XL version fits my Spectre x360 15-bl012dx versus a 15-bl051sa?

The KB06XL (also listed as HSTNN-DB7R, 902401-2C1, 902499-855) fits all listed 15-bl models including bl012dx and bl051sa; choose this single 79.2Wh capacity.
