55.8 Wh lithium-ion replacement battery

This 55.8 Wh lithium-ion battery replaces the original power cell in compatible HP Envy X360 convertibles. It ships new with a smart protection circuit built to the listed 11.55 V specification. The three-cell pack matches the OEM form factor for direct installation.

Replaces LK03XL L09281-855 and related part numbers

The unit covers the LK03XL, L09281-855, 916814-855 and a long list of alternate HP part numbers including HSTNN-LB7U and HSTNN-UB71. It is the correct swap when the original pack no longer holds a useful charge. The upgrade is worth it when runtime has dropped below your daily workload.

Verify your exact model code before ordering

Check the service tag or BIOS for the precise 15-bp, 15-bq, 15-cn, 15-cp, 17-ae, 17-bw or 17-ce variant listed in the compatibility data. Confirm the original battery carries one of the approved part numbers shown above. Ensure the laptop chassis accepts a three-cell 11.55 V pack before purchase.

Questions about this item

What dimensions or connector does the LK03XL battery need to fit the HP Envy X360 15-bp1xx chassis?

The LK03XL is a 3-cell lithium-ion pack built to the 11.55 V, 55.8 Wh form factor used in the HP Envy X360 15-bp, 15-bq, 15-cn and 15-cp series; it matches the original L09281-855 and 916814-855 part numbers.

How is the battery installed and which step do people often miss?

Power off the laptop, remove the bottom case screws, disconnect the old pack's cable from the motherboard, connect the new LK03XL cable firmly, then refit the case and screws before turning the system on.

When will the LK03XL need replacement and what should I watch for?

As a lithium-ion cell, the LK03XL will gradually lose capacity; plan to replace it once run-time drops below your needs or the smart chip reports a permanent capacity fault.
