About this replacement
Asus MeMO Pad ME170C — 3.8V Li-Polymer Replacement Battery (C11P1327)
This is a 3.8V 3900mAh Li-Polymer battery for the Asus MeMO Pad ME170C 7-inch Android tablet. It fits the ME170C, Fonepad 7" Dual SIM phablet, and K012 variants that share the same cell footprint and connector. Use the OEM part number C11P1327 or 0B200-00950000 to confirm fitment before ordering.
- ME170C and K012 platform fit: These models share the same 3.8V single-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol — which is why one cell covers both the standard MeMO Pad and the Fonepad dual-SIM variant without modification.
- Bench tested on actual hardware: We cycled this cell on the ME170C mainboard and confirmed the BMS initialised correctly, charge termination triggered at 4.35V, and the protection circuit responded to overcurrent within spec.
- Fuel gauge recalibration after swap: After fitting this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC calibration against the new cell and clears the inaccurate percentage readings that appear immediately after a replacement.
Why the ME170C shuts down at 15–25% remaining
The fuel gauge IC on the ME170C is calibrated against the original cell's internal resistance profile. When a new cell is installed, the IC does not yet know where the actual voltage cliff sits. Under combined display and Wi-Fi load, the cell voltage drops faster than the gauge predicts, and the protection circuit cuts power before the displayed percentage reaches zero. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets this mapping and resolves the early shutdown.
Fast charging unavailable on the ME170C after battery replacement
The ME170C charge IC negotiates charge rate based on a completed charge handshake with the battery BMS. On a fresh cell, this negotiation has not yet occurred, so the charger defaults to standard rate on the first cycle. After one full accepted charge cycle at standard rate, the IC recognises the cell and fast charge becomes available through supported chargers. If it still does not activate after two full cycles, check that the original Asus charger is in use — third-party adapters often lack the voltage negotiation signal the charge IC expects.
