It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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-AB001 Series — 11.55V Li-Polymer Replacement Battery (CN03XL)

This is an 11.55V, 4900mAh (56.6Wh) Li-Polymer cell that replaces the OEM CN03XL battery in the HP Spectre X360 13-AB001, 13-AB099, 13T-AB000, 13-AC033DX, and over 220 additional Spectre X360 variants. It matches the original voltage rail, physical footprint (268.10 × 125.70 × 4.00mm), and connector to the motherboard. Also cross-references as HSTNN-LB7L, 901308-421, 901345-855, and CN03057XL.

  • Spectre X360 13-AB and 13T-AB platform fit: These models share the same 11.55V three-cell Li-Polymer architecture, the same BMS handshake protocol, and the same flat-cable connector. One cell works across the full variant range because HP held that power rail constant through the AB and T-AB board revisions.
  • Bench tested on actual hardware: We ran this cell on a Spectre X360 13-AB001 board. The BMS initialised without error, charge current accepted at the full rate, and the BIOS recognised the cell without a firmware prompt. No charge-limit or authentication fault was triggered during the test cycle.
  • Post-install calibration on the Spectre X360: After fitting, run the laptop down to hibernate cutoff under normal load — do not force-shutdown — then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell and clears the inaccurate health warning that appears in HP Support Assistant after every cell swap.

Why the Spectre X360 shuts down at 20–30% charge shown

The Spectre X360 runs an Intel processor and a high-resolution touch display simultaneously. Under that combined load, the battery voltage drops faster than the fuel gauge predicts — especially with a new cell the gauge IC has never seen before. When cell voltage hits the low-voltage cutoff threshold, the BMS disconnects the pack and the laptop shuts down, even though the OS still shows 20–30% remaining. This is a calibration gap, not a faulty cell. Run two full discharge-to-hibernate then uninterrupted charge cycles, and the gauge IC recalibrates its discharge curve to match the actual cell chemistry.

BIOS reporting the replacement cell as poor health or unknown immediately after install

The HP BIOS reads battery health from EEPROM data written by the previous cell over its charge history. When a new cell goes in, that EEPROM record is either absent or mismatched, so the BIOS flags the battery as degraded or unknown — before the cell has been used once. This is not a fault with the replacement. To reset it, complete the one full discharge-to-hibernate cycle described above, then charge to 100% without interruption. After that cycle completes, recheck HP Support Assistant — the health status should update to normal.

Frequently Asked Questions

My Spectre X360 still shows 0% and won't charge after I fitted the new CN03XL cell — what's wrong?

The fuel gauge IC on the Spectre X360 board sometimes loses its reference point entirely when the old cell is removed, and the OS reports 0% or refuses to register a charge. Plug in the AC adapter and leave the laptop off for 20–30 minutes before powering on — this lets the BMS and fuel gauge IC initialise against the new cell with the charger present. If the issue persists, hold the power button for 15 seconds with the adapter connected to force an EC reset, then power on normally. The gauge should begin reading correctly within the first partial charge cycle.

The Spectre X360 is charging but stops at exactly 80% and won't go higher — is the new battery defective?

This is a BIOS-controlled charge limit, not a cell fault. HP's battery care firmware in the Spectre X360 BIOS includes an 80% charge cap that activates on some units to reduce long-term wear — it applies to the replacement cell exactly as it did to the original. Open the HP BIOS setup (F10 at boot), navigate to Power > Battery Care Function, and toggle the limit off. Alternatively, in Windows, check HP Support Assistant for a battery charge limit setting and disable it there.

Windows is showing the wrong Wh rating for the new battery — it says 43Wh but the cell is 56.6Wh. Should I be concerned?

The Wh figure Windows displays is read from the EEPROM on the cell, which stores the manufacturer's rated capacity value. The replacement cell's EEPROM value may differ slightly from what the old cell reported, or Windows is still caching the previous cell's data in its battery report. This does not affect how the cell charges or discharges — actual delivered capacity matches the 56.6Wh specification. Run one full discharge-to-hibernate cycle, then charge to 100%; Windows should update the reported Wh figure once the fuel gauge IC writes a fresh full-cycle record.
