Replacement battery for HP Spectre x360 15-BL series

This 6-cell lithium-polymer pack delivers 11.55V and 79.2Wh of capacity to restore mobility to compatible HP Spectre x360 15-BL and Pavilion 15T-BL notebooks. It replaces part numbers including HSTNN-DB7R, KB06XL, and 902499-855. The unit ships new with an instruction manual. Buyers needing a higher-wattage or 8-cell design should verify their original specification first.

Sustained output and cell balance

Six matched cells share the load evenly during long work sessions, keeping voltage stable as the pack discharges toward empty. Lithium-polymer chemistry resists memory effect, so partial top-ups do not reduce usable capacity over time. The 79.2Wh rating supports extended unplugged use on supported 15-inch convertible models. Units that have sat on a shelf for months may arrive at storage charge and need a full cycle to reach rated runtime.

Installation notes and common pitfalls

The package contains one battery and a manual; no tools are included. Before fitting, compare the connector position, cable length, and overall outline with the original battery shown in the listing images. Two physical variants exist for this part number, so visual confirmation prevents ordering the wrong shape. Forcing a mismatched connector or skipping the manual’s first-charge steps are the usual causes of early failure.

Questions about this item

Does the 11.55V 79.2Wh battery run hot or drain quickly when the Spectre x360 15-bl0XX is used all day?

The 6-cell lithium-polymer pack is rated at 11.55V and 79.2Wh, matching the original KB06XL specification so thermal behaviour and runtime stay the same as the factory battery.

What must I already have inside my HP Spectre x360 15-bl0XX for this HSTNN-DB7R to connect and work?

Your laptop needs the original KB06XL connector and cable routing; the replacement fits the same socket used on the 15-bl0XX, 15-bl1XX and Z6K96EA through Z6L02EA series.

Will this 6-cell 79.2Wh pack fit the older HP Pavilion 15T-BL000 and Z6K97EA models I still use?

Yes, the HSTNN-DB7R replaces part numbers 902499-855, 902499-856 and TPN-Q179, which are listed for Pavilion 15T-BL000, 15T-BL100 and the Z6K96EA to Z6L02EA family.
