Compatible Replacement Battery

This 41.7Wh lithium polymer battery replaces the BK03XL and several HP part numbers including 916366-421 and HSTNN-LB7S. It fits HP Pavilion x360 convertible models across the 14-ba0xx, 14-ba1xx and 14-ba2xx series as well as 14m-ba0xx and 14m-ba1xx variants. The pack supplies 11.55V and comes in black.

Who This Suits

Owners of the listed HP Pavilion x360 14-inch convertibles who need a direct replacement for a worn or failed original battery will find the correct voltage and connector here. Buyers who cannot confirm their exact battery model by opening the back cover should not purchase, as fit is not guaranteed for other series.

Capacity And Runtime

The 41.7Wh capacity delivers the same energy rating as the original BK03XL, providing comparable run time for typical productivity and media use on these 14-inch systems. Heavy workloads that push the CPU and display brightness will deplete the charge faster, and the pack offers no provision for extended-capacity upgrades beyond this rating.

Questions about this item

Does the BK03XL battery require any additional hardware to install in my HP Pavilion x360 14-ba0xx?

No extra hardware is needed; the package includes the 41.7Wh 11.55V battery and you only need a screwdriver to open the back cover and swap the old unit.

Will this 11.55V 3615mAh replacement work correctly alongside the original AC adapter that came with my 14-ba1xx series laptop?

Yes, the 11.55V output matches the original specification, so the existing charger will charge the new BK03XL to its full 41.7Wh capacity without any compatibility issues.

How can I verify the BK03XL is delivering its rated 41.7Wh after the initial charge cycles?

After completing the recommended three full charge-to-discharge cycles, check the battery report in Windows; the design capacity should read 41.7Wh and the full-charge capacity should be close to that figure.
