Direct replacement for Envy X360 15 series

This 55.8Wh lithium-ion battery fits HP Envy X360 convertible models across the 15-bp, 15-bq, 15-cn and 15-cp families. It carries part number LK03XL and replaces OEM codes such as L09281-855, 916814-855 and HSTNN-LB7U. The black pack weighs 0.64 and is supplied new for owners who need a like-for-like power source.

Thermals noise and power draw in daily use

The cell operates at 11.55V and delivers 4835mAh capacity for typical office and media workloads. Internal resistance stays low during normal discharge, so the pack runs cool and silent inside the chassis. No fan or active cooling is involved, keeping acoustic output at zero while the system draws power steadily.

Behaviour under sustained load

Under continuous demand the 55.8Wh rating supports extended sessions without voltage sag that would trigger early shutdown. The lithium-ion chemistry maintains stable output across the discharge curve, letting the laptop run demanding tasks for longer periods. Capacity remains consistent over repeated cycles when the pack is kept within normal temperature limits.

Questions about this item

How do I install the LK03XL battery in my HP Envy X360 15-bp series and which step is often missed?

Remove the bottom case screws, disconnect the old battery connector from the motherboard before lifting it out, then connect the new 11.55V pack and secure it; many forget to unplug the connector first.

What maintenance will the 55.8Wh Li-ion battery need over its life?

No scheduled maintenance is required; the 4835mAh cell will gradually hold less charge and should be replaced once runtime drops below your needs.

What limit appears first during sustained use of this 11.55V battery?

The 55.8Wh capacity determines how long the laptop runs before the voltage drops and the system shuts down to protect the cells.
