Fits HP Spectre X360 13-W001NF and replaces SH03XL, HSTNN-LB7L, TPN-Q178 battery packs.
11.55V 5000mAh lithium-polymer cell restores full charge cycles on this convertible ultrabook.
Connector seats into the internal slot below the keyboard deck without mechanical modification.
We cycled the pack across CPU and display load — BMS regulated thermal output cleanly through all discharge phases.
After installation, run one full discharge to hibernate-cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

HP Spectre X360 13-W001NF — 11.55V Li-Polymer Replacement Battery (SH03XL)

This is an 11.55V, 5000mAh (57.75Wh) Li-Polymer cell for the HP Spectre X360 13-W001NF and the broader SH03XL platform. It fits the convertible's three-cell bay and communicates directly with the EC via the standard HP smart battery interface. Replaces OEM part numbers SH03XL, 859026-421, 859356-855, HSTNN-LB7L, SH03057XL, and TPN-Q178.

  • SH03XL platform coverage: The Spectre X360 13-W and 13-AC series share the same battery bay geometry, connector pinout, and BMS handshake protocol — that is why one cell covers both lines. Voltage rail and SMBus communication requirements are identical across these models.
  • Bench tested on actual hardware: We ran this cell on a Spectre X360 13 unit and logged the BMS negotiation at startup. The EC recognised the cell immediately, accepted the charge cycle without interruption, and the fuel gauge IC initialised without a manual reset.
  • EC calibration after install: After fitting this cell, run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity curve and clears the inaccurate health warning that appears after every cell swap on this platform.

Why the Spectre X360 BIOS reports poor battery health after a cell swap

The Spectre X360 EC stores cycle count, charge history, and health data in the old cell's EEPROM. When a new cell installs, that EEPROM data is gone — the BIOS reads this as a degraded or unknown battery until it collects fresh data. The fuel gauge IC also needs several full cycles to map the new cell's discharge curve accurately. Running one complete discharge-to-hibernate followed by an uninterrupted charge to 100% starts that recalibration. After two to three full cycles, the health status in HP Support Assistant updates to reflect the actual cell condition.

Spectre X360 shutting down at 20–30% after battery replacement

This happens when the fuel gauge IC is still using the old cell's voltage-to-capacity curve. Under full CPU plus display load, the new cell's voltage drops faster than the EC predicts, hitting the firmware cutoff while the gauge still shows charge remaining. It is a calibration gap, not a fault with the replacement cell. Force a full discharge to the hibernate cutoff — do not interrupt it — then charge to 100% without unplugging. The EC recalculates the voltage cliff for the new cell and the premature shutdowns stop.

Frequently Asked Questions

The Spectre X360 shows 0% battery and "plugged in, not charging" right after I installed the new cell — what's wrong?

The EC sometimes fails to re-initialise the fuel gauge IC when a new cell is installed cold. Shut the laptop down completely, disconnect the charger, hold the power button for 15 seconds to drain residual charge from the board, then reconnect the charger before powering on. This forces the EC to restart the BMS handshake from scratch and the gauge should read correctly within one charge cycle.

HP Support Assistant is reporting the new battery's capacity as lower than the listed 57.75Wh — is the cell underspec?

No. The Wh figure in HP Support Assistant pulls from the EEPROM on the new cell, which reports rated chemistry values. The fuel gauge IC has not yet mapped actual capacity against the new cell's discharge curve. Run two full discharge-to-hibernate and charge-to-100% cycles — after the second cycle the reported Wh figure stabilises to match the cell's real output, typically within 1–2Wh of the rated 57.75Wh.

The Spectre X360 charges fine but the battery percentage jumps erratically — drops 10% in minutes then holds for an hour — is the cell faulty?

This is fuel gauge IC drift, not a defective cell. The IC is still using a lookup table built from the old battery's chemistry profile. We see this consistently on the bench for the first two or three cycles after a swap on this platform. Run a full uninterrupted discharge to hibernate, then charge to 100% without pulling the charger — repeat twice. The IC recalibrates its curve against the new cell and the percentage steps stabilise.
