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,

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 3-17ADA05 Series — 15.2V Li-Polymer Replacement Battery (L19L4PF2)

This is a 15.2V, 3600mAh (54.72Wh) Li-Polymer battery for the Lenovo IdeaPad 3-17ADA05, IdeaPad 3-17ARE05, IdeaPad 3-17IML05, and IdeaPad 3-17IIL05. It replaces OEM part numbers L19L4PF2, SB10W89847, and 5B10W89846. If your original cell has degraded or failed, this swap restores portable power to the machine.

  • IdeaPad 3 17-inch series fit: The ADA05, ARE05, IML05, and IIL05 variants all use the same 15.2V four-cell rail, identical connector pinout, and the same BMS handshake protocol — which is why one part number covers all four models.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on an IdeaPad 3 chassis. The BMS communicated correctly with the BIOS, charge current tapered as expected at top-of-charge, and no fault codes were logged during the test session.
  • Post-install calibration on IdeaPad 3: After fitting this battery, run the laptop down to hibernate-cutoff on battery only, then charge uninterrupted to 100% without unplugging. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

Why the IdeaPad 3 shuts down at 20–30% remaining after a battery swap

The IdeaPad 3 BIOS tracks a discharge curve learned from the original cell. When a new cell goes in, the stored curve no longer matches the actual voltage-to-capacity relationship of the fresh chemistry. Under full CPU plus display load, the new cell's real voltage drops faster than the BIOS expects, and the firmware triggers an emergency shutdown before the gauge reads zero. This is not a fault with the replacement cell. One full calibration discharge — run to hibernate, then charge to 100% uninterrupted — rewrites the learned curve and stops the premature cutoff.

BIOS reporting the new battery as "Unknown" or showing 0% on first boot

The BIOS reads health and capacity data from the EEPROM on the battery's BMS board. On first install, the system hasn't yet completed a handshake cycle against the new cell's EEPROM, so it reports unknown status or zero charge. This clears after the first complete charge cycle — plug in, charge to 100% without interruption, then reboot. If the warning persists after two full cycles, check that the battery connector is fully seated; a partial connection breaks the data line even when the power pins are making contact.

Frequently Asked Questions

My IdeaPad 3 shows the new battery's Wh rating as lower than the original — is something wrong with the cell?

The Wh figure displayed in Lenovo Vantage or Device Manager is read from the EEPROM on the BMS board, and different cell batches can carry slightly different rated values even at the same nominal capacity. The actual delivered energy is determined by the cell chemistry, not the EEPROM label. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — after that cycle the OS fuel gauge IC will have measured the real cell capacity and the displayed figure will stabilise.

The fuel gauge is jumping around wildly — it reads 60%, then 80%, then 45% within a few minutes of use. What's happening?

The fuel gauge IC inside the laptop calculates state-of-charge by tracking voltage and current against a stored model of the battery's discharge curve. A brand-new cell has a discharge curve the IC has never seen, so its estimates are erratic for the first few cycles. This is not a fault — it corrects itself. Run two to three full discharge-to-hibernate cycles followed by full uninterrupted charges, and the gauge will lock onto the new cell's actual curve and read accurately.

Lenovo Vantage is showing battery health as "Poor" immediately after fitting the new cell — should I be worried?

No. Lenovo Vantage reads health status from EEPROM data written during the BIOS battery learn cycle. Until the laptop has completed at least one full calibration cycle against the new cell, the BIOS has no valid data and defaults to a poor-health flag. Run the laptop down to hibernate on battery only — no AC connected — then charge uninterrupted to 100% and reboot. Vantage should clear the poor-health warning after that cycle completes.
