Huawei dtab Compatible Battery HB3484V3EAW-12 3.8V 6000mAh

Huawei dtab / Mediapad M2 10.1 — 3.8V Li-Polymer Replacement Battery (HB3484V3EAW-12)

This 3.8V, 6000mAh Li-Polymer battery replaces OEM part HB3484V3EAW-12 in the Huawei dtab, d-01H, Mediapad M2 10.1 LTE, and M2-A04L. It restores power to the display, processor, and radio stack when the original cell can no longer hold a usable charge. Rated at 22.8Wh, it matches the factory cell's footprint at 210.90 × 82.65 × 3.00 mm.

• dtab / d-01H / Mediapad M2 10.1 compatibility: These four models share the same battery bay dimensions, 3.8V charge rail, and connector pinout. The BMS handshake across this group is identical, so one cell covers the full set without firmware conflicts.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Mediapad M2 10.1 LTE. The BMS accepted the charge curve without tripping overcurrent protection, and the fuel gauge IC communicated correctly once a full calibration cycle was completed.
• Fuel gauge IC reset after installation: After fitting this battery, run the tablet down to automatic shutoff — do not force-power-off — then charge uninterrupted to 100% before unplugging. The fuel gauge IC calibrates its reference window against the new cell during this first full cycle, correcting the inaccurate percentage readings that appear immediately after a swap.

Tablet shutting down at 15–25% remaining after battery replacement

This happens when the fuel gauge IC still holds the voltage-to-capacity curve mapped to the old, degraded cell. The new cell has a steeper voltage cliff under combined display and Wi-Fi load, so the system hits its low-voltage cutoff while the gauge still reads 15–25%. Running one complete discharge cycle to automatic shutoff and then a full uninterrupted charge resets the fuel gauge's reference points. After that cycle, the reported percentage will track actual cell voltage accurately.

Fast charging unavailable on the Mediapad M2 10.1 after a battery swap

The Mediapad M2 10.1's charge IC uses a protocol handshake on the first accepted charge cycle to enable higher-rate charging modes. Immediately after installation, the controller defaults to standard 5V input until that first cycle completes. Plug in using the original Huawei charger — third-party adapters can suppress the handshake — and let the tablet charge to 100% without interruption. Fast charge becomes available from the second cycle onward once the charge IC logs a completed session.
