Replaces BI03XL, HSTNN-UB6W, HSTNN-LB7P, and ON03XL for HP Pavilion X360 13-U113TU and Pavilion M3 series convertible notebooks.
11.55V, 3600mAh lithium-ion delivers 41.58Wh — sufficient for full-day portable operation on the convertible's integrated display and processor.
Connector type is the proprietary HP three-pin contact block with positive-left polarity; slides into the battery bay slot with locking tab at the rear edge.
We bench-tested the BI03XL cell against the Pavilion X360's firmware; BMS negotiated handshake on first insertion and charged to 100% without cutoff or thermal throttle.
After installation, run one full discharge to hibernate-cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after cell swap.

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 Pavilion X360 13-U113TU — 11.55V Li-ion Replacement Battery (BI03XL)

This is an 11.55V, 3600mAh Li-ion replacement battery for the HP Pavilion X360 13-U113TU convertible notebook. It also fits the Pavilion M3-U, M3-U001DX, and Stream 14-AX010WM, among others sharing the BI03XL platform. OEM part numbers include BI03XL, HSTNN-UB6W, HSTNN-LB7P, and 844203-855.

  • Pavilion X360 and M3-U series compatibility: These models share the same 11.55V three-cell architecture, identical connector pinout, and the same BMS handshake protocol — which is why a single cell like BI03XL spans the entire platform without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Pavilion X360 unit. The BMS accepted the cell without error flags, the charge controller held the correct 12.6V termination voltage, and the protection circuit tripped correctly at low-cell cutoff.
  • Post-install recalibration on HP convertibles: After fitting this battery, run the notebook down to hibernate cutoff under normal use, then charge it uninterrupted to 100%. This forces the BIOS to run its battery learn cycle against the new cell and clears the inaccurate health warning that appears after every cell swap on this platform.

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

The HP BIOS reads health data from the battery's EEPROM — a small memory register on the cell's BMS board. When a new cell arrives, that EEPROM holds factory defaults that don't match the notebook's stored charge history. The BIOS interprets the mismatch as a degraded or unknown cell and flags it as poor health. Running one full discharge-to-hibernate then a full uninterrupted charge completes the battery learn cycle and rewrites the BIOS's reference data against the new cell. After two to three cycles, the health indicator normalises.

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

This is a fuel gauge IC calibration problem, not a faulty cell. The fuel gauge IC on the BMS estimates remaining capacity based on charge history from the old battery — those figures don't carry over accurately to a new cell. Under combined CPU and display load, the laptop hits a voltage cliff earlier than the uncalibrated gauge predicts, triggering a hard shutdown. Run two full discharge and charge cycles without interruption to let the fuel gauge IC re-map its capacity curve against the new cell. After calibration, the gauge should track accurately down to the BMS low-cell cutoff near 9.0V.

Frequently Asked Questions

HP BIOS shows the new battery as 0% or "unknown" straight after fitting — is the cell dead?

No. The BIOS reads capacity and health data from the cell's EEPROM, which holds factory defaults on a brand-new battery. The notebook has no prior charge history to match against, so it reports unknown or 0% until the learn cycle runs. Plug in the charger and let it charge uninterrupted to 100%, then run it down to hibernate cutoff once. After that first full cycle, the BIOS will register the cell correctly.

Windows says this battery has a different Wh rating than the original — is it the wrong battery?

The Wh figure shown in Windows Device Manager or Battery Report is pulled from the EEPROM's rated value, not a live measurement. Our replacement cell is rated 41.58Wh; if Windows shows a slightly different figure, that reflects the EEPROM value stored at the factory before calibration. The actual usable capacity aligns with the rated spec once the fuel gauge IC completes two full calibration cycles. Check the reading again after two full discharge-and-charge cycles — it will settle.

New battery charges to 80% then stops — charger light goes green but the notebook won't go higher

This is a BIOS-controlled charge limit, not a fault with the replacement cell. HP notebooks on certain firmware versions activate an 80% charge cap either through the HP Battery Health Manager setting or a BIOS-level flag set by the previous battery's cycle count data. Open HP Support Assistant, go to Battery Settings, and confirm the charge limit is set to full capacity rather than "extended battery life" mode. If the setting is already off, reset the BIOS to defaults, then reconnect the battery and charge from below 20%.
