HP Pavilion X360 Replacement Battery - Replaces NP03XL

Why this battery

Fits HP Pavilion X360 convertible laptops; replaces NP03XL, HSTNN-LB6L, 760944-421, and 761230-005 OEM part numbers.
11.4V and 3750mAh capacity delivers 42.75Wh — enough to sustain full CPU plus display load without voltage sag on this 13-inch 2-in-1.
Connector seats straight into the battery bay slot with a single locking tab on the right side; no rotation needed.
We bench-tested the cell against a Pavilion X360 13-A010DX under sustained load; BMS held steady at 11.4V nominal, no early cutoff.
After installation, run one complete discharge to hibernation-cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings.

About this replacement

HP Pavilion X360 — 11.4V Li-Polymer Replacement Battery (NP03XL)

This is an 11.4V, 3750mAh (42.75Wh) lithium-polymer battery for the HP Pavilion X360 convertible notebook. It fits the TPN-Q146, TPN-Q147, TPN-Q148, and TPN-Q149 board revisions, along with the Pavilion X360 13-A010DX and the broader Pavilion X360 range. OEM cross-references include HSTNN-LB6L, 760944-421, 761230-005, and 767068-005.

Pavilion X360 TPN-Q146 through TPN-Q149 compatibility: These four board variants share the same 11.4V three-cell lithium-polymer rail, connector pinout, and BMS handshake protocol — which is why a single cell replaces all of them without modification.
Bench tested on actual hardware: We ran this cell on a TPN-Q147 unit. The BMS completed charge acceptance without flagging a fault, voltage held steady under combined CPU and display load, and the fuel gauge IC registered cell capacity within one calibration cycle.
Post-installation discharge cycle on the X360: After fitting this cell, run the laptop on battery until it hibernates at low charge, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting the NP03XL

The HP BIOS stores learned capacity data from the previous cell in a battery learn table. When a new cell goes in, that table still reflects the old, degraded values — so the system flags the health as poor before it has measured the new cell at all. This is not a fault with the replacement. The BIOS needs one full discharge-to-hibernate followed by an uninterrupted charge to 100% to rewrite the learn table against the new chemistry. After that cycle, the health indicator should return to normal.

Pavilion X360 shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge maps a voltage reading to a percentage based on old cell data, so it under-reports remaining charge — and the laptop hits its low-voltage cutoff while the screen still shows 20–30%. The fix is to complete two or three full discharge-and-charge cycles without interruption. After calibration, the cutoff aligns with the displayed percentage, and the laptop should reach the screen-off hibernate point below 5%.
