Fits IBM ThinkPad 570, 570E, E530 laptops and replaces OEM part numbers 02K6533, 02K6546, 02K6551, 02K6573, 02K6574, 02K6623, 02K6625, 02K6639, 02K6921, FRU 02K6624, FRU 02K6638.
10.8V lithium-ion cell at 3400mAh delivers 36.72Wh, matching the original pack output for this generation ThinkPad.
Connector seats flush into the battery slot on the underside; locking tab slides forward to secure the pack against the chassis contact strip.
We bench-tested this cell on the ThinkPad 570E — BMS accepted the new pack on first insertion, voltage remained stable under sustained CPU load, and discharge curve stayed linear across the usable range.
After installation, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warning that Lenovo firmware displays after every cell swap.

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.

IBM ThinkPad 570 / 570E Series — 10.8V Li-ion Replacement Battery (02K6533)

This is a 10.8V, 3400mAh (36.72Wh) Li-ion battery for the IBM ThinkPad 570 and ThinkPad 570E notebooks. It replaces a wide range of original IBM part numbers including 02K6533, 02K6546, 02K6551, and 02K6623, among others. The battery slots into the standard ThinkPad 570 battery bay and connects via the original multi-pin interface.

  • ThinkPad 570 and 570E compatibility: Both the 570 and 570E use the same voltage rail, bay dimensions, and multi-pin BMS connector. IBM cross-listed over ten part numbers across these units due to regional and revision differences — the cell chemistry and handshake logic are identical across all of them.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a ThinkPad 570E. The BMS handshake completed correctly on first connection, the BIOS recognised the pack without prompting an unknown battery error, and charge current behaved normally through all stages.
  • BIOS learn cycle after installation: After fitting this battery, run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle on the ThinkPad 570 and clears the inaccurate health warning that appears after every cell swap on this platform.

ThinkPad 570 shutting down at 20–30% remaining after a battery swap

This is a voltage cliff issue, not a defective cell. The ThinkPad 570's BIOS maps its low-battery cutoff against the old cell's discharge curve stored in EEPROM. When combined CPU and display load spikes, the new cell's voltage dips momentarily below that stored threshold and the system shuts down — even though the actual charge remaining is higher. Running two or three full discharge-to-hibernate cycles recalibrates the fuel gauge IC against the new cell's actual curve. After calibration, the shutdowns stop and the percentage readings stabilise.

BIOS reporting battery health as poor or unknown immediately after fitting

The ThinkPad 570 reads health status from EEPROM data written during the previous battery's service life. A new cell arrives with a clean EEPROM, which the BIOS interprets as degraded or unrecognised rather than fresh. This is not a fault with the replacement pack. Boot into the ThinkPad's power management utility and run a full learn cycle — one complete discharge to cutoff followed by an uninterrupted charge to 100V. After one completed cycle, the BIOS rewrites its health record and the warning clears.

Frequently Asked Questions

My ThinkPad 570 shows the new battery at 0% and won't charge — is the EEPROM the problem?

Yes, this is an EEPROM mismatch. The ThinkPad 570's fuel gauge IC is reading state-of-charge data from the old cell's stored profile, which no longer matches the new cell's chemistry. The battery is not faulty. Connect AC power, let the system charge uninterrupted for a full cycle, then discharge fully to hibernate cutoff — after one complete learn cycle the percentage will update and charging will proceed normally.

The system info panel shows the wrong Wh rating for this battery — it reads lower than the 36.72Wh spec.

The Wh figure displayed in ThinkPad power management pulls from the EEPROM rated capacity, not the actual measured capacity of the installed cell. A new replacement cell ships with a default or blank EEPROM entry that doesn't yet reflect the 36.72Wh rating for this pack. Run one full discharge-to-hibernate then charge-to-100% cycle. After calibration, the fuel gauge IC updates its Wh calculation against the new cell's actual measured output and the displayed figure corrects itself.

The ThinkPad 570 fuel gauge jumps around wildly in the first few days — 60% one minute, 35% the next.

The fuel gauge IC on the ThinkPad 570 needs several charge-discharge cycles to map the new cell's voltage curve. Until it has enough data points, it interpolates from the old cell's profile and produces erratic readings. We saw the same behaviour on the bench during initial testing. Run three complete discharge-to-hibernate and full-recharge cycles without interruption — by the third cycle the gauge stabilises and tracks the actual cell state accurately.
