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 11-S001TU Series — 7.6V Li-ion Replacement Battery (PP02XL)

This is a 7.6V, 4750mAh (36.1Wh) Li-ion replacement battery for the HP Pavilion 11-S001TU, 11-S002TU, and 11-S003TU notebooks. It matches the original PP02XL cell format, connector, and BMS communication protocol. Drop voltage or capacity mismatches cause charging refusal — this cell avoids both.

  • Pavilion 11-S series compatibility: The S001TU, S002TU, and S003TU share the same 7.6V battery rail, TPN-Q166 board designation, and four-pin SMBus connector. Any cell deviating from these specs will trip the charge controller and refuse to charge.
  • Bench tested on actual hardware: We ran this cell on a Pavilion 11-S unit and monitored BMS handshake, charge acceptance, and cutoff thresholds. The controller recognised the cell immediately, charged to full without interruption, and hit the expected 8.4V peak before taper.
  • Post-install calibration on the Pavilion 11-S: After fitting this battery, run the laptop on battery only until it reaches hibernate cutoff — do not interrupt it. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false "poor health" warning that appears after any cell swap on this platform.

Pavilion 11-S shutting down at 20–30% shown after battery swap

This happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell has different internal resistance, so the voltage drops faster under combined CPU and display load than the gauge predicts. The controller reads voltage and concludes the pack is near empty — even when the percentage shown says otherwise. Running two full discharge-to-hibernate cycles recalibrates the IC against the new cell and brings the reported percentage back in line with actual voltage.

BIOS reporting wrong Wh rating after fitting the PP02XL

The Wh figure shown in BIOS or Windows Battery Report is pulled from the cell's EEPROM, not measured live. Some PP02XL-compatible cells carry EEPROM data reflecting the OEM rated value rather than the actual chemistry capacity of the replacement cell. This is a data mismatch, not a fault. Check the live "Full Charge Capacity" value in Windows — open PowerShell and run powercfg /batteryreport, then look at the HTML report for the FULL CHARGE CAPACITY column to confirm the cell is charging to its actual 36.1Wh.

Frequently Asked Questions

My HP Pavilion 11-S is showing "plugged in, not charging" straight after fitting the new PP02XL — what's wrong?

This usually means the BIOS charge controller didn't complete its handshake with the new cell's BMS on first boot. Shut the laptop down completely, remove the AC adapter, hold the power button for 15 seconds to drain residual charge from the board, then reconnect AC and boot. This forces the charge controller to re-initiate the SMBus communication cycle with the new cell and clears the stuck "not charging" state.

Windows battery report shows the PP02XL at 0% health and flags it as "unknown" — is the cell faulty?

It isn't faulty. The health percentage in Windows is calculated against the EEPROM design capacity from the old cell stored in the BIOS battery learn table. The new cell hasn't completed a learn cycle yet, so the OS has no valid baseline and defaults to 0% or "unknown." Run one full discharge to hibernate cutoff followed by an uninterrupted charge to 100% — after that cycle, the BIOS learn table updates and the health reading normalises.

The fuel gauge on the Pavilion 11-S jumps around wildly in the first few days — reads 60%, then drops to 15% within minutes. Is this a bad cell?

The fuel gauge IC in this platform calibrates its discharge curve against cycle history. A new cell has no history, so the IC is extrapolating from old data and the percentage output is unreliable. The jumps are a calibration lag, not a cell defect. Run two complete discharge-to-hibernate cycles with an uninterrupted charge to 100% each time — by the third cycle the IC has enough data to track the new cell accurately and the gauge stabilises.
