Huawei MediaPad M2 10.1 Compatible Battery HB26A510EBC 3.8V

Huawei MediaPad M2 10.1 — 3.8V Li-Polymer Replacement Battery (HB26A510EBC)

This is a 3.8V, 6650mAh lithium-polymer replacement battery for the Huawei MediaPad M2 10.1 tablet series. It carries OEM part number HB26A510EBC and fits the standard MediaPad M2 10.1, TD-LTE variant, Youth edition, and Youth TD-LTE edition. Capacity is rated at 25.27Wh, matching the original cell specification.

• MediaPad M2 10.1 series compatibility: All listed variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The charge IC on the mainboard reads cell identification data from the same register across the standard and Youth models, so one part number covers the full lineup.
• Bench tested on actual hardware: We cycled this battery through charge and discharge on a MediaPad M2 10.1 mainboard. The BMS accepted the new cell without error flags, the charge IC transitioned through CC and CV phases correctly, and the protection circuit tripped at the expected low-voltage cutoff threshold.
• Fuel gauge recalibration after swap: After fitting this battery, run the tablet down to automatic shutoff — do not force-power it off — then charge it uninterrupted to 100% without using the tablet. This gives the fuel gauge IC one full cycle against the new cell and clears the percentage drift that almost always appears after a replacement.

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

This happens because the fuel gauge IC is still calibrated to the discharge curve of the old, degraded cell. When the new cell hits a voltage the IC associates with a lower state of charge, it signals a shutdown before the battery is actually empty. The display backlight and active Wi-Fi together draw enough current to cause a sharp voltage sag at that threshold, which triggers the cutoff. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — after that cycle, the IC maps its curve to the new cell and the early shutdowns stop.

MediaPad M2 10.1 showing wrong battery percentage after swap

The percentage shown on screen comes from the fuel gauge IC, not the battery directly. That IC stores a learned model of the old cell's capacity and voltage profile, so a new cell with full capacity reads as mismatched from the first boot. You'll typically see the percentage jump or drop several points during light use, or read 100% and then drop to 85% within minutes. Fix it by discharging the tablet fully to automatic shutoff, then charging in one uninterrupted session to 100% — the IC writes a new baseline at the 4.35V full-charge point and the display stabilises.
