HTC P3300 ARTE160 Replacement Battery 3.7V 2400mAh

HTC P3300 / Artemis Series — 3.7V Li-ion Replacement Battery (ARTE160)

This 3.7V, 2400mAh Li-ion battery is a direct replacement for the HTC P3300, P3350, Artemis, and Love smartphones. It slots into the original battery bay and restores power to devices where the factory cell has degraded. Voltage and capacity match OEM spec: 3.7V nominal, 8.88Wh.

• P3300 / P3350 / Artemis / Love compatibility: All four models share the same battery bay dimensions and connector pinout, drawing power through the same 3.7V rail with an identical BMS handshake — one cell fits all four without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the P3300 platform. The BMS accepted the cell on first connection, charge current ramped normally, and the protection circuit triggered correctly at the low-voltage cutoff threshold.
• Fuel gauge recalibration on first use: After fitting this cell, run one full discharge to auto-shutoff followed by an uninterrupted full charge before using the device normally. The P3300's fuel gauge IC needs one complete cycle to map the new cell's discharge curve — skip this and the percentage readout will drift from the first charge.

Why the P3300 reports wrong battery percentage after a cell swap

The P3300 uses a coulomb counter that stores a discharge curve calibrated to the original cell's impedance profile. A new cell has a different internal resistance, so the counter's stored curve no longer maps accurately to actual charge state. The device reads stored data, not live cell chemistry. One complete discharge-to-cutoff followed by a full charge resets the reference and brings percentage reporting back into alignment.

Sudden shutdown at 20–30% on the replacement cell

This happens when the Windows Mobile OS triggers a screen-on or data-sync load spike and the cell voltage drops sharply under current draw — crossing the BMS undervoltage threshold before the gauge reaches 0%. It is a voltage-cliff issue, not a capacity defect. On a freshly installed cell that has not been calibrated, the fuel gauge overstates remaining charge and the BMS cuts power without warning. Run a full recalibration cycle first; if shutdowns persist after that, check that the battery contacts are clean and seated flat — a high-resistance connection amplifies voltage sag at load.
