About this replacement
Huawei MediaPad 10 Link / S10-201W — 3.7V Li-Polymer Replacement Battery (HB3X1)
The HB3X1 is a 3.7V, 6400mAh Li-Polymer cell that powers the Huawei MediaPad 10 Link, S10-201W, and S10-201WA tablets. This replacement restores the tablet to full operating capacity when the original cell has degraded or stopped holding a charge. Voltage, connector pinout, and physical dimensions match the OEM specification.
- MediaPad 10 Link / S10-201W platform fit: The S10-201W and S10-201WA share the same battery bay geometry, flex connector, and BMS handshake as the standard MediaPad 10 Link. One cell revision covers all three variants without any modification to the housing or connector.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the MediaPad 10 Link platform. The BMS accepted the cell on first connection, charge termination triggered correctly at full capacity, and no voltage anomalies appeared under combined display-plus-WiFi load.
- Fuel gauge reset after installation: After fitting this cell, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using the device. This forces the fuel gauge IC to recalibrate against the new cell's actual voltage curve and eliminates the inaccurate percentage readings that appear immediately after a swap.
Tablet shutting down at 15–25% remaining after battery replacement
This is a voltage cliff issue, not a cell defect. When the display backlight and WiFi radio draw simultaneously, the combined load pulls the cell voltage down faster than the fuel gauge IC expects based on its old calibration data. The system interprets the voltage dip as a critically low state and triggers an emergency shutdown before the gauge reads zero. Run one complete discharge cycle to automatic shutoff, then charge to 100% uninterrupted — this recalibrates the IC against the new cell's actual discharge curve and moves the shutdown threshold back to the correct voltage floor.
Fast charging not resuming after battery swap on the MediaPad 10 Link
Huawei's charge protocol requires the charge IC on the new cell to complete at least one full accepted charge cycle before the controller re-enables higher current delivery. Immediately after installation, the tablet defaults to standard 5V charging as a safety measure. Charge the tablet fully from below 10% without interruption. After that first complete cycle, fast charge behaviour returns on supported chargers — confirm with the original Huawei charger before swapping the cable or adapter.
