Replacement Battery for HP Spectre x360 15-BL

This 11.55V lithium-ion pack delivers 79.2Wh and 6858mAh across six cells. It replaces OEM part numbers KB06XL, 902499-855, HSTNN-DB7R, 902401-2C1, 902499-856 and KB0607. The unit fits HP Spectre x360 15-BL000, 15-BL100 and other 15-BLXXX models.

Installation Notes and Common Issues

The battery sits inside the chassis and requires removing the bottom cover and disconnecting the original pack. Most problems arise when the connector is not fully seated or when screws are overtightened and strip the plastic posts. A clean workspace and the correct Torx driver prevent damage.

Sustained Load Behaviour

Under continuous discharge the six-cell design maintains stable voltage thanks to built-in circuit protection and low self-discharge. CE, FCC and RoHS certifications confirm the safety circuitry handles prolonged current draw without overheating. Capacity remains consistent across long sessions rather than dropping after a short burst.
