Replacement battery for HP Envy X360 15-bp series

This 52.5Wh lithium-ion battery operates at 11.55V across four cells and weighs roughly 0.63lb. It replaces part numbers including LK03XL, 916814-855, L09281-855 and HSTNN-LB7U. The pack ships new with two screwdrivers to simplify installation. Grade A cells are specified for fast charging and low power draw.

Check your current part number and voltage

Verify that the existing battery carries one of the listed part numbers such as 916368-421, L09280-855 or HSTNN-UB71. Confirm the laptop model appears in the supported list, covering Envy X360 15-bp, 15-bq, 15m-bp, 15m-bq, 15m-cp, 15m-cn and Envy 17-ae, 17m-ae, 17-bw series. Ensure the system voltage requirement matches 11.55V before ordering.

Upgrade from a depleted or lower-capacity original

This unit replaces the factory 4-cell pack when runtime has dropped or the battery no longer holds charge. The 52.5Wh capacity restores the original design runtime for compatible Envy models. The jump is worth it when the old cell shows swelling, rapid discharge or failure to calibrate. Buyers needing higher capacity than 52.5Wh or a different voltage should look elsewhere.
