Replacement battery for HP Pavilion X360 14-BA

This lithium-polymer battery delivers 11.55V and 41.7Wh across three cells. It is built as a direct replacement for the original BK03XL unit in compatible Pavilion X360 convertible laptops. The black housing matches the original appearance. It is intended for owners of the listed models who need to restore mobile runtime.

Two screwdrivers included for installation

The package supplies two screwdrivers so you can open the chassis and swap the battery without sourcing tools separately. This reduces the friction of a user-serviceable repair. No software or drivers are bundled because the component is a pure hardware replacement. The accessories change the practical difficulty of the job, not the electrical function.

Li-polymer cells with multi-circuit protection

The pack integrates overcharge, overdischarge, over-temperature and short-circuit safeguards to protect both the battery and the laptop. Rated for up to 500 recharge cycles over its service life. The internal connector matches the motherboard header on the supported 14-BA and 14M-BA models. Buyers whose laptop uses a different battery part number or form factor cannot use this unit.
