HTC MTeoR Replacement Battery BERR160 3.7V 1250mAh

HTC MTeoR / Breeze Series — 3.7V Li-Polymer Replacement Battery (BERR160)

This 3.7V, 1250mAh Li-Polymer cell replaces the original battery in the HTC MTeoR, Breeze, Breeze 100, and Breeze 160. It matches OEM part numbers BERR160 and 35H00068-01M. Voltage and physical dimensions are exact — 64.58 × 41.71 × 5.94mm.

• MTeoR and Breeze platform compatibility: These four models share the same battery bay dimensions, connector pinout, and 3.7V supply rail. The BMS handshake protocol is identical across the series, so one cell covers all four devices without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the MTeoR platform. The BMS accepted the cell immediately, charge termination triggered correctly at 4.2V, and the protection circuit tripped as expected under a deliberate over-discharge test.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.

Why the MTeoR reports wrong battery percentage after a cell swap

The fuel gauge IC on the MTeoR stores a discharge curve from the old cell in its coulomb counter. When a new cell goes in, that stored curve no longer matches the actual cell chemistry. The phone reads voltage against the old curve and reports a percentage that drifts — sometimes showing 80% and then cutting to low battery without warning. One full discharge-to-cutoff followed by a full charge resets the coulomb counter and aligns it to the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops below the modem or screen load threshold before the displayed percentage reaches zero — a voltage cliff rather than a slow drain. The fuel gauge is still referencing the old cell curve, so it reports 25% remaining while the actual cell voltage has already fallen below 3.5V under load. The BMS then triggers a hard cutoff to protect the cell. Run one full calibration cycle — discharge until the phone shuts off on its own, then charge uninterrupted to 100% — to correct the curve.
