About this replacement
Xiaomi MiPad 7.9 — 3.8V Li-Polymer Replacement Battery (BM60)
The BM60 is a 3.8V, 6500mAh lithium-polymer cell for the Xiaomi MiPad 7.9 tablet. It fits the standard MiPad 7.9, MiPad 7.9 WiFi, and A0101 variants including the 16GB model. This battery replaces the original when the tablet fails to hold charge, shuts down unexpectedly, or no longer powers on from a depleted state.
- MiPad 7.9 and A0101 compatibility: The MiPad 7.9, MiPad 7.9 WiFi, and A0101 variants share the same physical cell footprint, connector pinout, and BMS handshake protocol. Swapping between these models is not necessary — one BM60 cell covers all listed variants.
- Bench tested on actual hardware: We ran the BM60 through charge and discharge cycles on a MiPad 7.9 unit. The BMS accepted the charge cycle without fault flags, and the charge IC reached full cutoff at the correct 4.35V ceiling.
- Fuel gauge recalibration after swap: After fitting this battery, run the tablet down to automatic shutoff without plugging in, then charge uninterrupted to 100%. This single full cycle resets the fuel gauge IC against the new cell and eliminates the inaccurate percentage readings that typically appear after a battery swap.
Tablet shutting down at 15–25% remaining after battery swap
The MiPad 7.9 drives a backlit display and active WiFi simultaneously, which creates a combined load spike that can pull cell voltage below the BMS cutoff threshold before the fuel gauge reads zero. The fuel gauge IC is still calibrated to the discharge curve of the old, degraded cell — so its percentage estimate does not match the new cell's actual voltage. When real voltage drops under load, the BMS trips before the reported percentage reaches 0%. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resyncs the gauge to the new cell's curve.
Fast charging not available after fitting the BM60
Xiaomi's fast charge protocol requires the charger and the device to complete a handshake negotiation. On a freshly installed cell, this negotiation sometimes fails during the first charge cycle because the BMS has not yet completed an accepted full charge event. Plug the tablet into the original Xiaomi charger and allow one full charge from low battery to 100% without interruption. After that cycle completes, fast charge negotiation resumes normally on subsequent sessions.
