I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.

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 Envy 14 Series — 10.8V Li-ion Replacement Battery (HSTNN-LB4N)

This 10.8V, 4400mAh (47.52Wh) Li-ion battery replaces the original cell in the HP Envy 14, Envy 14t, Envy 14z, and Envy 14 Touch series notebooks. It matches the OEM voltage rail and connector pinout for the HSTNN-LB4N, PI06, TPN-Q117, TPN-Q119, TPN-Q120, and TPN-Q121 part numbers. Install it when the original cell no longer holds adequate charge or fails to charge at all.

  • Envy 14 platform compatibility: The Envy 14, 14t, 14z, and 14 Touch share the same 10.8V three-cell architecture and identical six-pin smart connector. The BMS handshake protocol is consistent across these variants, so one cell covers the full range without firmware conflict.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an Envy 14 Touch unit. The BMS initialised correctly on first connection, charge acceptance registered immediately, and the protection circuit tripped at the expected low-voltage cutoff threshold without anomaly.
  • Post-install calibration on Envy 14: After fitting this cell, run the laptop down to hibernate cutoff under normal use — do not force-shutdown — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Envy 14 hardware.

BIOS reporting poor battery health immediately after fitting a new cell

The HP Envy 14 BIOS reads health data from EEPROM registers stored on the battery's fuel gauge IC — not from the cell chemistry directly. When a new cell installs, those registers still reflect the degraded state of the old battery. The BIOS flags "poor health" or "consider replacing" because it hasn't yet run a full learn cycle against the new cell's actual capacity curve. One complete discharge-to-hibernate followed by a full uninterrupted charge resets the register values and clears the warning.

Laptop shutting down at 20–30% charge shown on screen

This is a voltage cliff issue, not a calibration problem. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC predicts — the BMS hits the low-voltage cutoff threshold while the OS gauge still shows 20–30% remaining. It happens most often in the first few cycles before the fuel gauge IC has mapped the new cell's discharge curve. Run two to three full discharge-and-charge cycles; the IC recalibrates its voltage-to-percentage mapping and the early shutdowns stop. If the problem persists past five cycles, check that the battery resting voltage reads at least 10.8V on a multimeter before load is applied.

Frequently Asked Questions

HP Envy 14 showing "0% available (plugged in, charging)" after fitting the new battery — what's happening?

The fuel gauge IC on the new cell hasn't synchronised its EEPROM state with the HP BIOS yet. The BIOS is reading stale register data and reporting 0% even though the cell is physically charging. Shut the laptop down completely, leave it charging for 30 minutes powered off, then boot. If it still reads 0%, run the laptop to hibernate cutoff on battery only, then charge uninterrupted to 100% — this forces a full learn cycle and corrects the readout.

System info shows the wrong Wh rating for this battery — HP Support Assistant lists a different number than what's printed on the cell. Is the battery faulty?

The Wh figure in HP Support Assistant is pulled from the EEPROM on the battery's fuel gauge IC, which stores the rated design capacity — not the measured capacity of the actual cells inside. A 47.52Wh cell may report a slightly different value in software if the EEPROM was programmed to a nominal figure during manufacturing. This is not a fault. Cross-check the physical label on the battery against the product spec; if voltage reads 10.8V on a multimeter at rest, the cell is correct.

New battery charges fine but the HP Envy 14 won't go above 80% — is charge limiting on?

HP BIOS includes a Battery Care function that caps charge at 80% to reduce cell wear — it ships enabled on many Envy units and survives a battery swap because the setting lives in BIOS, not on the battery. Open HP Support Assistant, go to Battery Check, and look for the Battery Care Mode or Adaptive Battery Charging toggle. Turn it off, then plug in and let the cell charge past 80% to confirm it reaches 100%.
