Orange SPV C100 Replacement Battery BTR5600B 3.7V 2200mAh

Orange SPV C100 / C500 Series — 3.7V Li-ion Replacement Battery (BTR5600B)

This is a 3.7V, 2200mAh Li-ion cell built to fit the Orange SPV C100, C500, C500S, and C550 smartphones. It replaces the original battery when the cell has aged past the point of holding a usable charge. Capacity figure is 8.14Wh — taken from the product data, not estimated.

• SPV C100 / C500 family fit: These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol across the series. One cell covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through full discharge and recharge on the SPV platform. The BMS accepted the charge cycle without interruption and voltage held stable across the curve with no mid-cycle cutoff.
• Fuel gauge recalibration on first cycle: On first use after fitting, run one full discharge down to automatic shutoff, then charge uninterrupted to 100% before using the device heavily. The SPV fuel gauge IC reads a stored curve from the old cell — this single cycle overwrites it with data from the new cell and stops erratic percentage readings early on.

Sudden shutdown at 20–30% on the SPV C500 after a cell swap

The SPV's fuel gauge IC was calibrated against the discharge curve of the original aged cell. A new cell has a steeper voltage drop near the bottom of its capacity range. When the phone hits that drop under screen or modem load, the IC interprets the voltage sag as an immediate cutoff threshold — even though the cell still has charge left. This is not a faulty battery. Run one complete discharge-to-shutoff cycle followed by a full uninterrupted charge. After that single calibration cycle, the IC maps the correct voltage curve and shutdowns below 30% stop occurring.

SPV C100 not powering on after sitting in storage

Li-ion cells in long-term storage self-discharge. If the cell drops below approximately 2.5V per cell, the BMS enters lockout mode to prevent damage — and the phone will not respond to the power button or show any charging indicator. Connect the phone to a charger and leave it for 20–30 minutes without pressing anything. The charge IC will trickle current into the cell until it clears the BMS recovery threshold, typically around 2.8V, at which point normal charging resumes and the phone powers on.
