Replacement battery for HP convertibles

The KingSener NP03XL is a 43WH lithium-ion unit built for HP Pavilion X360 13-A010DX and ENVY x360 15 models including u010dx, u011dx, u110dx, u111dx and u170ca. It replaces part numbers NP03XL, TPN-Q146, TPN-Q147, TPN-Q148, TPN-Q149, HSTNN-LB6L, HSTNN-UB6L, 760944-421 and 760944-541. Buyers needing a different voltage or capacity should look elsewhere.

Black lithium-ion pack at 11.4V

The pack uses lithium-ion cells assembled in China and ships in a black housing that matches the original chassis colour. It fits the internal battery bay of the listed convertibles without adapters or cable modifications, so installation follows the standard service procedure for those models. Units requiring a proprietary connector not listed above will not be compatible.

43WH capacity for everyday mobility

Rated at 43WH and 11.4V, the battery delivers the energy budget designed for the target platforms under normal workloads. Thermal behaviour follows the laptop's own management firmware, and power draw stays within the original specification envelope. Systems with higher-wattage CPUs or discrete GPUs that exceed the original design envelope may see reduced run time.
