LXHY LA04 43Wh 11.4V laptop battery

Replacement battery for HP convertibles

This 11.4 V lithium-ion pack replaces the NP03XL and compatible part numbers across HP Envy X360 and Pavilion X360 models. It is built for owners who need a direct swap without adapter cables or firmware tricks. The cell chemistry matches the original specification for voltage and form factor. Buyers with non-listed HP chassis or other brands should look elsewhere.

43 Wh capacity for daily mobility

The 43 watt-hour rating supports typical mixed workloads such as web browsing, document editing and video playback on the supported 13-inch and 15-inch convertibles. Runtime scales with screen brightness, CPU load and background services; heavy compute or sustained gaming will deplete the pack faster. The three A-grade cells provide stable output until the low-voltage cutoff engages. Users expecting all-day operation under maximum load will find the capacity insufficient.

Drop-in fit with included tools

The battery occupies the same internal bay as the factory unit and uses the existing screw points; two screwdrivers are supplied in the package. No soldering, ribbon-cable adapters or BIOS updates are required for installation. Physical dimensions match the original envelope, so chassis clearance is unchanged. Builders who need a higher-capacity alternative or a different voltage platform cannot use this unit.
