Orange SPV M650 Replacement Battery ARTE160 3.7V 2400mAh

Orange SPV M650 — 3.7V Li-ion Replacement Battery (ARTE160)

This is a 3.7V, 2400mAh Li-ion replacement battery for the Orange SPV M650 smartphone. It fits the original battery bay using the same connector and cell format as the factory unit. OEM part references are ARTE160 and 35H00062-04M.

• SPV M650 fit: The M650 uses a single-cell Li-ion pack with a proprietary connector that carries both power and fuel gauge data back to the Windows Mobile charge IC. This cell matches that footprint — 51.43 × 38.47 × 13.08mm — and the BMS communicates correctly with the onboard fuel gauge hardware.
• Bench tested on actual hardware: We cycled this cell through charge and load on the bench. The BMS held cutoff cleanly at low voltage and accepted charge from the standard SPV M650 charge circuit without tripping the protection circuitry.
• First-cycle fuel gauge reset: After fitting this cell, run one full uninterrupted discharge to near-empty, then charge to 100% before normal use. The M650's fuel gauge IC was calibrated to your worn original cell — one complete cycle lets it re-anchor the discharge curve to the new 2400mAh cell and stop reporting inaccurate percentages.

Sudden shutdown at 20–30% on the SPV M650

This is a voltage cliff failure, not a calibration issue. When the M650 pulls peak current for screen backlight, GSM radio bursts, or data sync, an aged or high-impedance cell drops its terminal voltage below the BMS cutoff threshold — even though the fuel gauge still shows charge remaining. The phone interprets the voltage collapse as a dead cell and shuts down instantly. Fitting a fresh 2400mAh cell with lower internal impedance eliminates the sag that triggers that cutoff. After fitting, run a full calibration cycle so the fuel gauge maps the new voltage curve correctly from 100% down to 3.0V.

Phone won't power on after the battery sat in storage

Li-ion cells in storage self-discharge slowly. If the SPV M650 was stored for several months with the battery installed, the cell may have dropped below 2.5V — the threshold where the BMS locks out to prevent damage. The phone will show no response to the power button and may not register on the charger immediately. Connect the phone to its original charger and leave it untouched for 20–30 minutes — the charge IC will trickle current into the cell until it recovers above the BMS re-enable threshold, typically around 2.9V, at which point normal charging resumes.
