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.
Sincerely,
Michael

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.

Lenovo IdeaPad 330-15ICH / 330-17ICH — 11.34V Li-Polymer Replacement Battery (L17M3PB1 / 5B10Q71251)

This is an 11.34V 3900mAh (44.23Wh) Li-Polymer battery for the Lenovo IdeaPad 330-15ICH and 330-17ICH series laptops. It replaces a degraded or failed original cell and restores full portable operation. It cross-references multiple OEM part numbers including L17M3PB1, L17C3PB0, L17D3PB0, and 5B10Q71251.

  • IdeaPad 330-15ICH and 330-17ICH fitment: Both the 15-inch and 17-inch 330 ICH variants share the same 11.34V three-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. One battery covers the full ICH sub-family without any modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on IdeaPad 330-series hardware. The BMS authenticated correctly, the fuel gauge IC initialised without error flags, and the BIOS accepted the cell without throwing an unknown battery warning on first boot.
  • Post-install calibration cycle: After fitting this battery, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Lenovo Vantage after every cell swap.

Laptop shuts down at 20–30% remaining after battery swap

The IdeaPad 330 BIOS maps its shutdown threshold against the old cell's discharge curve stored in EEPROM. A new cell with a different internal resistance profile hits a voltage cliff under combined CPU and display load before the fuel gauge IC registers zero. The system reads a valid percentage but the cell voltage drops below the BMS protection floor under load, triggering an abrupt cutoff. Run two full calibration cycles — full discharge to hibernate, full uninterrupted charge to 100% — and the fuel gauge IC will remap its curve against the new cell, resolving the premature shutdowns.

BIOS reports battery health as "Poor" or "Replace Now" on first boot

This flag is triggered by the BIOS comparing the new cell's EEPROM data against the health history logged from the old battery. It is not a defect in the replacement cell. The Lenovo EC (embedded controller) needs at least one complete learn cycle to overwrite the cached health data. Charge to 100%, discharge fully to hibernate cutoff, then charge back to 100% without interruption — after that cycle the health status in Lenovo Vantage will update to reflect the actual condition of the new cell.

Frequently Asked Questions

The battery percentage on my IdeaPad 330 jumps around — it shows 60% then suddenly drops to 15% with no warning. Is the new cell faulty?

The fuel gauge IC on the IdeaPad 330 mainboard calibrates its charge curve against real discharge data from the physical cell. After a cell swap, the IC is still using the old curve, so the percentage reading is unreliable until it learns the new cell's behaviour. Run two full cycles — discharge to hibernate cutoff, then charge uninterrupted to 100% each time — and the readings will stabilise. After the second cycle, the fuel gauge IC will have enough data to track the new cell accurately.

Windows shows my IdeaPad 330 battery as 44Wh in Device Manager but the system info page in Lenovo Vantage shows a different Wh figure. Which one is correct?

The Wh figure in Lenovo Vantage is pulled from the EEPROM on the battery controller, which stores the rated capacity of the original cell. Windows Device Manager calculates Wh from the actual voltage and current the cell is delivering in real time. The product data Wh rating of 44.23Wh is the correct figure for this cell. Disregard the Vantage figure until after one full calibration cycle, at which point the EC re-reads the cell and updates its stored value.

My IdeaPad 330 stops charging at 80% and will not go higher, even with the new battery installed.

The IdeaPad 330 BIOS includes a firmware-controlled charge limit called Conservation Mode, which caps charging at 60% or 80% depending on the setting. This is a BIOS policy — not a cell fault and not caused by the replacement battery. Open Lenovo Vantage, go to Power, then Battery, and check whether Conservation Mode is switched on. Turn it off and the charge ceiling will return to 100%.
