41.7Wh Li-polymer replacement for HP Pavilion X360

This E-buy battery supplies 41.7Wh at 11.55V using a Li-polymer cell pack finished in black. It is built as a direct swap for the original BK03XL unit installed in Pavilion X360 14-BA convertibles. The part arrives new and ready to install without additional adapters. Owners of compatible models can restore original run time with a single component change.

Check your current part number

Verify that the existing battery carries one of the listed part numbers such as BK03XL, HSTNN-LB7S, HSTNN-UB7G, 916366-421 or 916811-855. Confirm the laptop model matches the supported 14-BA series including suffixes like 033TX, 034TX, 035TX through 049TX and 100TX, 101TX, 104TX, 105TX, 106TX, 107TX or 111TX. Mismatched part numbers or model codes will prevent correct fit and electrical connection.

Replaces the factory BK03XL pack when capacity has

This unit takes the place of the original 41.7Wh battery once it no longer holds a useful charge. The upgrade is worthwhile when the laptop shuts down early, reports reduced capacity in the OS or requires constant mains power. It restores the same voltage and watt-hour rating without altering the chassis or connector layout. Users needing a higher capacity than 41.7Wh will not find that option in this listing.
