Compatible HP models

This replacement battery fits HP laptops using part numbers NU03XL, HSTNN-UB6V, 843536-541 or 844201-855. It is built for the Pavilion X360 11-U000 series and systems carrying the TPN-W117 or TPN-C128 board identifiers.

Voltage and capacity limits

The pack delivers 11.55V with a 41.7Wh energy rating and 3615mAh charge capacity. Lithium-polymer chemistry sets the practical ceiling at this voltage and watt-hour figure; higher draw or longer runtime requires a physically larger pack.

Runtime and replacement scope

A 41.7Wh cell comfortably powers typical ultraportable workloads for several hours per charge. It will not extend runtime beyond the original factory specification and does not support models outside the listed HP part numbers or the Pavilion X360 11-U000 line.

Questions about this item

Is the 41.7Wh NU03XL the only capacity offered for the HP TPN-W117 and TPN-C128?

The listing shows a single 41.7Wh NU03XL unit that replaces part numbers NU03XL, HSTNN-UB6V, 843536-541 and 844201-855. No alternative capacities are mentioned.

What runtime can I expect from the 41.7Wh capacity once the battery is installed in my Pavilion X360 11-U000?

At 11.55V and 3615mAh the pack stores 41.7Wh; actual runtime depends on the laptop's power draw, screen brightness and workload, so exact hours cannot be given.

Does the NU03XL use a proprietary HP connector or a standard interface, and does that limit compatibility?

The battery is built to match the original HP connector for the TPN-W117, TPN-C128 and Pavilion X360 11-U000 models listed.
