Lenovo Yoga Tab 3 10 L15D3K32 Replacement Battery 3.6V 8200mAh

Lenovo Yoga Tab 3 10 — 3.6V Li-ion Replacement Battery (L15D3K32)

This is a 3.6V, 8200mAh Li-ion replacement battery for the Lenovo Yoga Tab 3 10. It fits the YT3-X50 series, including YT3-X50F and ZA1N0039NZ variants. It matches OEM part numbers L15D3K32, L15C3K32, and 5B18C03587.

• YT3-X50 series compatibility: The YT3-X50 line shares a common battery bay geometry and connector pinout across the F and M sub-variants. The BMS on each uses the same voltage thresholds and communication protocol, so one cell spec fits all units in this series.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a YT3-X50F board. The BMS accepted the cell without fault codes, charge current ramped correctly through CC/CV phases, and the protection circuit triggered cleanly at low-voltage cutoff.
• Fuel gauge recalibration after swap: After installation, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. The Yoga Tab 3's fuel gauge IC is calibrated against the old cell's impedance curve. One complete cycle resets that baseline against the new cell and clears inaccurate percentage readings.

This happens when the fuel gauge IC still holds calibration data from the old, degraded cell. The tablet's power management interprets a voltage dip under combined display and Wi-Fi load as a critically low state and forces shutdown — even though usable charge remains. It is not a fault with the new cell. Run one full discharge cycle to automatic shutoff, then charge to 100% without interruption. After that cycle, the fuel gauge re-anchors its empty-voltage reference and the early shutdowns stop.

The percentage display is driven by a fuel gauge IC that tracks charge by counting coulombs against a stored capacity model built on the original cell. Fit a new cell and that stored model no longer matches actual cell behaviour, so the reported percentage drifts — often reading 100% while the tablet still charges, or jumping from 40% to 5% with no load change. The fix is a single recalibration cycle: discharge fully to automatic shutoff, then charge uninterrupted to 100%. After one complete cycle the IC updates its model to match the new cell's actual voltage curve.
