Lenovo Yoga 920 L16C4P61 Compatible Battery 7.68V 8800mAh

Lenovo Yoga 920-13IKB — 7.68V Li-Polymer Replacement Battery (L16C4P61)

This is a 7.68V, 8800mAh (67.58Wh) Li-Polymer battery for the Lenovo Yoga 920 and Yoga 920-13IKB convertible laptop. It replaces OEM parts L16C4P61, L16M4P60, and 5B10N01565. If your original cell is failing to hold charge or BIOS is flagging poor battery health, this swap restores portable operation.

• Yoga 920-13IKB platform fit: The 920 series runs a 7.68V two-cell Li-Polymer architecture with a dedicated BMS that handshakes directly with the Lenovo EC firmware. Every variant in the 920-13IKB lineup — including 80Y7 and 80Y8 submodels — shares the same connector pinout, voltage rail, and BMS communication protocol, which is why all three OEM part numbers cross-reference to this single cell.
• Bench tested on actual hardware: We ran this cell on a Yoga 920-13IKB unit and confirmed the BMS completed full handshake with the EC, accepted charge from the 65W USB-C adapter, and held voltage across a full discharge cycle without triggering low-voltage cutoff prematurely.
• First-cycle reset after install: After fitting this cell, run the laptop down until it hibernates on battery cutoff, then charge uninterrupted to 100% without using the machine. This forces the BIOS battery learn cycle to complete against the new cell's actual capacity data and clears the inaccurate health warning that appears after every cell swap on Lenovo firmware.

BIOS reporting battery health as poor after replacement

The Yoga 920 BIOS reads health data from EEPROM registers written by the original factory cell. When a new cell is installed, those registers don't match the new cell's chemistry profile, so the firmware flags poor or unknown health immediately. This is a firmware calibration issue, not a cell defect. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% rewrites the learn cycle data and clears the warning. If the warning persists past three full cycles, check that the EC firmware is on the latest Lenovo update for the 920-13IKB platform.

Laptop shuts down at 20–30% shown on the fuel gauge

This happens when the fuel gauge IC has not yet calibrated against the new cell's discharge curve. The old cell's voltage-to-capacity table is still cached, so the IC calls 20–30% remaining at a voltage point that is actually near cell minimum under load — the CPU and display draw together create enough sag to trigger the hardware cutoff. Run two full discharge-to-hibernate cycles and the fuel gauge IC will rebuild its curve against the actual chemistry. After calibration, the shutdown threshold should align with the reported percentage at approximately 3.0V per cell under load.
