Asus MeMO Pad ME172 Replacement Battery C11-ME172V 3.75V

Asus MeMO Pad ME172V — 3.75V Li-Polymer Replacement Battery (C11-ME172V)

This is a 3.75V, 4250mAh Li-Polymer replacement battery for the Asus MeMO Pad ME172 series 7-inch Android tablet. It fits the ME172, ME172V, and ME172-GY08 variants using OEM part number C11-ME172V. Swap it in when the original cell no longer holds a charge or the tablet shuts down unexpectedly under load.

• ME172 series compatibility: All ME172 variants share the same 3.75V single-cell architecture, C11-ME172V connector pinout, and BMS handshake — the charge IC reads cell state through the same communication line across the entire model range.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an ME172V unit. The BMS accepted the charge IC handshake without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• Fuel gauge recalibration after swap: After installing this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate against the new cell and clears the inaccurate percentage readings that appear after a swap.

MeMO Pad ME172 shutting down at 15–25% remaining

When the display backlight and WiFi radio draw current simultaneously, the combined load causes a sharper voltage sag than the fuel gauge IC anticipates. The BMS sees the cell voltage drop below the protection threshold and cuts power before the reported percentage reaches zero. This is a fuel gauge calibration problem, not a faulty battery. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets the calibration curve — after that, the shutdown point should track accurately below 5%.

Battery percentage jumping or freezing after installation

The ME172's fuel gauge IC stores a learned discharge curve from the original cell. A new cell with a different internal resistance profile causes the IC to report incoherent state-of-charge values — jumps of 10–20% or a percentage that stays frozen for extended periods are both symptoms of this mismatch. The fix is a single recalibration cycle: discharge fully until the tablet shuts itself off, then charge to 100% without interruption. After one complete cycle, the IC maps the new cell's voltage curve and percentage reporting stabilises.
