Replacement battery for HP Envy and Pavilion x360

This 11.4V lithium-polymer pack is built as a direct replacement for the NP03XL part used in select HP Envy X360 15-inch and Pavilion X360 13-inch convertibles. It matches the original 43Wh capacity and four-cell layout so the laptop recognises it without BIOS updates. The unit ships new and ready to install.

Thermals noise and power draw

Li-polymer chemistry keeps self-discharge low and the pack runs cool during typical charge and discharge cycles. Built-in protection circuits guard against short circuit, over-voltage, over-current and deep discharge, which helps maintain stable temperatures. No moving parts mean silent operation.

Capacity and cycle life

Rated at 43Wh, the battery delivers the same energy budget as the factory unit and is rated for about 300 to 500 full charge cycles before capacity drops noticeably. Buyers needing longer runtime per charge or a higher-wattage pack for intensive workloads should look elsewhere.

Questions about this item

How do I install the NP03XL 43Wh battery in my HP Envy X360 15-u010dx, and what step do people often miss?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery connector before lifting it out, then connect the new NP03XL connector firmly before reassembling; the step most often missed is unplugging the old battery cable first.

What maintenance or replacement will the NP03XL 11.4V Li-polymer battery need later?

The battery is rated for about 300 to 500 charge cycles; after that capacity drops noticeably, so plan to replace the NP03XL pack once runtime no longer meets your needs.

What limit shows up first under sustained use of the NP03XL 43Wh pack?

The 43 watt-hour capacity and 11.4 volt output set the runtime ceiling; under continuous load the pack will hit its cycle-life limit of 300 to 500 cycles before any other constraint appears.
