HP Envy X360 15 & Pavilion X360 13 battery
This 43Wh 11.4V Li-polymer pack replaces the original NP03XL cell in HP Envy X360 15-u series and Pavilion X360 13-a series convertibles. It uses Grade A four-cell construction rated for roughly 300 to 500 full charge cycles. The unit ships with two screwdrivers and a manual for immediate installation. Buyers needing a higher capacity pack for longer unplugged runtime cannot use this model.
Thermal and power behaviour in daily use
The battery operates at 11.4 volts and delivers 43 watt-hours without active cooling, so it adds no fan noise to the chassis. Built-in circuitry provides short-circuit, over-voltage, over-current and discharge protection during charging and heavy loads. The pack weighs about nine ounces and fits the existing bay without increasing system heat output. Users who require a 20V 85W AC adapter specification will find that detail absent from this battery.
Build quality and connector implications
The black Li-polymer housing meets CE, FCC and RoHS certification and uses the original NP03XL connector layout for a direct fit. Included screwdrivers simplify the bottom-case removal on compatible Envy and Pavilion X360 models. The four-cell design keeps the profile slim so the convertible hinge and 360-degree rotation remain unobstructed. Owners of laptops outside the listed HP part numbers 761230-005 and 760944-421 cannot use this replacement.

Questions about this item
How do I install the NP03XL battery and what step is often missed?
Remove the bottom cover screws with the included screwdrivers, disconnect the old battery cable, connect the new NP03XL 11.4V 43Wh pack, then reattach the cover screws — many forget to reconnect the cable before closing the case.
What maintenance or replacement will the NP03XL battery need later?
The 4-cell Li-polymer pack is rated for about 300 to 500 charge cycles; after that capacity drops and the battery should be replaced.
What limit appears first during sustained use of the NP03XL battery?
The 43Wh capacity sets runtime; under continuous load the battery will reach its discharge limit before any thermal protection triggers.
