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 ThinkPad T570 — 15.28V Li-Polymer Replacement Battery (00UR891)

This 15.28V, 2050mAh (31.32Wh) lithium-polymer cell replaces the internal battery in the Lenovo ThinkPad T570 15.6-inch business laptop. It matches OEM part numbers 00UR891, 00UR892, SB10L84122, SB10L84123, 00UR890, 01AV493, and SB10L84121. Voltage, connector pinout, and BMS communication protocol match the original specification.

  • ThinkPad T570 compatibility: All T570 variants in this listing share the same 15.28V four-cell architecture, identical flex connector, and the same BMS handshake required by the EC firmware — so one cell covers the full T570 lineup regardless of sub-model suffix.
  • Bench tested on actual hardware: We ran this cell on a T570 motherboard and confirmed the BMS authenticated correctly, the EC reported a valid battery presence, and charge current stepped down normally through CC to CV without tripping a fault state.
  • First-cycle recalibration on ThinkPad T570: After fitting this cell, let the laptop discharge fully until it hibernates on its own, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false "poor health" warning the EC generates whenever it detects EEPROM data from a previous cell.

Why the T570 BIOS flags a new battery as poor health immediately after install

The ThinkPad EC reads charge history and wear data stored in the old cell's EEPROM. When a new cell arrives with a blank or mismatched EEPROM profile, the EC has no learned capacity baseline to compare against and defaults to a poor-health flag. This is a firmware behaviour, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the EC enough data to build a new baseline and clear the warning.

T570 shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual chemistry. The gauge still uses voltage curves mapped to the old, degraded cell, so it misreads the remaining charge and triggers a shutdown well before the cell is actually empty. It is not a fault in this replacement cell. Run two to three full discharge-to-hibernate and full-charge cycles — after that the gauge re-maps its curve and the shutdowns stop. Confirm calibration is complete by checking that the EC reports voltage above 14.8V at the 20% display mark.

Frequently Asked Questions

The T570 shows the replacement battery as "0% available (plugged in, charging)" and won't move off zero — what's happening?

The EC is failing to read valid EEPROM data from the new cell and is holding charge display at zero until it authenticates a known profile. Disconnect the AC adapter, hold the power button for 15 seconds to clear the EC state, reconnect AC, and let the laptop charge without interruption. If the gauge still sticks at 0% after a full charge cycle, enter ThinkPad Setup (F1 at boot), navigate to Config → Power, and run the battery reset from there to force a fresh learn cycle.

System Information shows this battery as 31Wh but Windows reports a much lower "designed capacity" — is the cell faulty?

This is an EEPROM rated-versus-actual mismatch. The Wh figure Windows reads comes from the value written into the cell's EEPROM at manufacture, while the 31.32Wh on the listing reflects the actual electrochemical capacity of the new cells. The two numbers will converge after the EC completes a full battery learn cycle — discharge to hibernate, then charge uninterrupted to 100%, and check Windows Battery Report again with `powercfg /batteryreport` to confirm the designed capacity has updated.

The T570 charge stops at 80% and the battery never reaches 100% even after hours on AC — is this a fault?

This is almost always the BIOS charge threshold, not a cell fault. Lenovo's Power Manager firmware lets the EC cap charging at 80% to reduce calendar aging — check Start → Lenovo Vantage → Power → Battery Charge Threshold and confirm the upper limit is set to 100%. If Vantage is not installed, enter ThinkPad Setup (F1 at boot), go to Config → Power → Battery Charge Threshold, and set the stop-charging value to 100.
