Fits Lenovo ThinkPad Air 14 and replaces OEM part L17C4PB0, 5B10Q16067, 5B10Q16066, 5B10Q22883, 5B10W67403, L17M4PB0, SB10W67331.
7.68V lithium-polymer cell rated 5800mAh delivers 44.54Wh — matches original capacity for full runtime restoration on Air 14.
Connector seats flush into the battery slot with standard Lenovo latch; no adapter needed on this platform.
We bench-tested this cell on Air 14 hardware; BMS negotiated full voltage on first insertion without fault codes or charge limiting.
After installation, run one complete discharge to sleep mode then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears false health warnings that appear after cell swaps.

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 Air 14 / Flex 6-14 / IdeaPad 530S — 7.68V Li-Polymer Replacement Battery (L17C4PB0)

This 7.68V, 5800mAh (44.54Wh) lithium-polymer battery replaces the L17C4PB0 cell in the Lenovo Air 14, Flex 6-14, Flex 6-14IKB, and IdeaPad 530S-15IKB (81EV), along with 139 additional compatible models. It uses the same connector, BMS pinout, and voltage rail as the original Lenovo cell. Capacity figures are taken directly from product data — not estimated.

  • Air 14 / Flex 6-14 / IdeaPad 530S-15IKB platform fit: These models share the L17C4PB0 form factor because they run the same 7.68V two-cell Li-Polymer architecture with identical BMS handshake requirements. The BIOS on each reads cell voltage and EEPROM data through the same SMBus protocol — one cell swap covers all variants in this cluster.
  • Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the Air 14 platform. The BMS authenticated correctly, the BIOS acknowledged the cell without error flags, and charge current stepped down at the expected voltage threshold approaching 100%.
  • Post-install discharge cycle: After fitting this cell, run one full discharge to the hibernate-cutoff point, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears on almost every cell swap in this platform.

Why the IdeaPad 530S shuts down at 20–30% remaining after a battery swap

The fuel gauge IC on this platform tracks cell capacity using learned data from the previous cell. When a new cell goes in, that stored data is wrong — the IC thinks the voltage cliff arrives earlier than it actually does on fresh chemistry. Under combined CPU and display load, the laptop hits what it believes is the safe-cutoff threshold and shuts down, even though real charge remains. Running two to three full discharge-to-hibernate cycles recalibrates the fuel gauge against the new cell's actual voltage curve and moves the shutdown point back to the correct level.

BIOS reporting the replacement cell as "poor health" or unknown immediately after install

The BIOS reads health status from EEPROM data embedded in the battery's BMS — not from live cell measurements. On first boot with a new cell, the EEPROM cycle count and wear data have not yet been written by the Lenovo firmware, so the BIOS flags the battery as unknown or degraded. This is a firmware-state issue, not a fault with the cell. Complete the full discharge-to-hibernate and uninterrupted charge cycle described above, then check battery status again — the BIOS should report normal health once the learn cycle has written fresh data to the EEPROM.

Frequently Asked Questions

My Lenovo Air 14 is showing the wrong Wh rating in system info after I swapped the battery — is something wrong with the cell?

No. The Wh figure shown in system info is pulled from the EEPROM on the battery's BMS, and on a fresh replacement cell that data hasn't been written by Lenovo's firmware yet. The actual chemistry is correct at 44.54Wh — the display mismatch is a reporting lag, not a cell fault. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%, and the system info readout should update to the correct value.

My Lenovo IdeaPad 530S-15IKB stops charging at 80% and won't go higher — did I get a faulty battery?

Almost certainly not. Lenovo's BIOS includes a built-in charge limit setting that caps charging at 80% to reduce long-term cell stress — it ships enabled on many units and survives battery swaps. Open Lenovo Vantage (or the older Energy Management utility), navigate to Power, then Battery, and check whether "Conservation Mode" or "Battery Charge Threshold" is active. Disable it, then plug in and confirm the charge climbs past 80%.

The fuel gauge on my Flex 6-14 is jumping around wildly — showing 60%, then 45%, then 70% within minutes of unplugging.

This is the fuel gauge IC recalibrating against unfamiliar chemistry after a cell swap. The IC uses a model built on the old cell's behaviour, and until it sees several real discharge cycles on the new cell, its state-of-charge estimates will be erratic. Run two to three full discharge cycles — drain to the point the laptop hibernates, then charge uninterrupted to 100% each time. After the third cycle the gauge IC will have enough data to track the new cell accurately and the jumping will stop.
