11.31V, 4100mAh lithium-polymer cell matches the original pack voltage and capacity for this 14-inch ultrabook.
Connector slides straight in; no physical modification needed; verify the locking tab seats flush before closing the battery door.
We bench tested this pack on the Lenovo platform; the BMS initialized without fault codes and held voltage under sustained CPU load.
After installation, run one full discharge to hibernate cutoff then charge uninterrupted to 100% to reset the BIOS battery learn cycle and clear false health warnings.

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 Slim 5 14ABR8 — 11.31V Li-Polymer Replacement Battery (5B11K39362)

This is an 11.31V, 4100mAh (46.37Wh) Li-Polymer battery for the Lenovo IdeaPad Slim 5 14ABR8 series. It fits the 82XE variant range, including 82XE0001RK through to the broader 82XE lineup. Cross-reference OEM part numbers L22B3PA3, L22C3PA3, L22D3PA3, L22L3PA3, L22M3PA3, 5B11N45396, or SB11K39363 before ordering.

  • IdeaPad Slim 5 14ABR8 series compatibility: All 82XE variants share the same three-cell Li-Polymer pack, connector pinout, and BMS handshake. The voltage rail sits at 11.31V nominal — any deviation trips the EC and prevents charging from starting.
  • Bench tested on actual hardware: We ran this pack on a 14ABR8 chassis. The BMS initialised on first boot, the EC recognised cell chemistry without firmware prompts, and charge current ramped correctly through CC/CV phases to full capacity.
  • Post-install discharge cycle: After fitting, 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 appears after every cell swap on this platform.

BIOS reporting battery health as poor immediately after replacement

The IdeaPad Slim 5 EC reads health data from the battery's EEPROM on first connection. When a new cell arrives with factory EEPROM values that differ from the old pack's learned data, the BIOS flags it as degraded or unknown. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate then a full uninterrupted charge — the BIOS battery learn cycle rewrites the stored health data against the new cell's actual charge curve. The warning clears after one to two calibration cycles.

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

The fuel gauge IC on this platform maps state-of-charge against the old cell's discharge curve stored in memory. A new cell has a different voltage-versus-capacity profile, so the IC misreads remaining charge and triggers shutdown well before the pack is actually empty. The cutoff happens because the reported voltage hits the low-threshold before the gauge recalibrates. To fix it, run two full discharge-to-hibernate and charge-to-100% cycles — by the second cycle, the fuel gauge IC recalibrates to the new cell and the percentage readout stabilises above 11.1V at the point the laptop would otherwise shut down.

Frequently Asked Questions

The Lenovo battery health widget says "poor health" or shows 0% capacity on a brand-new replacement — is the cell dead?

No — the BIOS is reading stale EEPROM data from the old pack, not measuring the new cell. Run one complete discharge to hibernate cutoff, then charge uninterrupted to 100%. That triggers the battery learn cycle on the IdeaPad Slim 5 EC and rewrites the health data. The poor health flag clears within one to two full cycles.

Windows is showing the wrong Wh rating in Device Manager after swapping the battery on my IdeaPad Slim 5 — it says 41Wh but the new cell is 46Wh. Which is correct?

The 46.37Wh figure from the cell's chemistry is correct. What Windows reports in Device Manager pulls the rated design capacity from the EEPROM on the old pack's learned data, not from a fresh measurement of the new cell. After one full discharge-to-hibernate and charge-to-100% cycle, the EC updates the stored Wh value to match the new pack. Verify in Device Manager under the Battery section — it should read 46Wh or close to it after recalibration.

My IdeaPad Slim 5 14ABR8 cuts out abruptly when I open a heavy application right after the replacement — the charge shows 25% when it dies. Why?

This is a voltage cliff issue, not a capacity issue. Under combined CPU and display load, the new cell's voltage drops faster than the fuel gauge IC expects based on its old calibration data — it reads 25% but the actual cell voltage has already fallen past the EC's low-voltage cutoff threshold. Two full discharge-to-hibernate cycles recalibrate the IC against the new cell's load curve. After calibration, the shutdown threshold aligns with actual remaining voltage, typically stabilising above 10.8V at the point the laptop previously cut out.
