Orange SV10B Replacement Battery 3.7V 950mAh Li-ion SPV E200

Orange SPV E200 — 3.7V Li-ion Replacement Battery (SV10B / SV16A)

This is a 3.7V Li-ion replacement battery rated at 950mAh (3.52Wh) for the Orange SPV E200 smartphone. It replaces OEM part numbers SV10B and SV16A — the two original battery references used across SPV E200 production runs. Fit the cell, close the back cover, and the phone powers up as it should.

• SPV E200 compatibility: The SPV E200 uses a single-cell Li-ion pack with a 3.7V nominal rail. Both SV10B and SV16A share the same footprint, contact layout, and cell voltage, so this replacement covers either variant without modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the SPV E200 platform. The BMS accepted charge current without fault, the protection circuit tripped correctly at the low-voltage cutoff, and the phone held power through the full discharge curve without unexpected shutdowns.
• Fuel gauge recalibration on first use: After fitting this replacement, run the SPV E200 down to automatic shutdown on first use, then charge it uninterrupted to 100% before switching off. The Windows Mobile fuel gauge IC needs one full cycle against the new cell's discharge curve to report percentage accurately.

Why the SPV E200 shuts down suddenly at 20–30% after a cell swap

The SPV E200's fuel gauge IC stores a discharge curve calibrated to the original cell's internal resistance profile. A new cell has a different impedance, so the gauge's voltage-to-percentage mapping is off until it recalibrates. Under modem or display load, the phone draws a short current spike that pulls cell voltage below the hardware cutoff before the gauge has registered low battery. The fix is one complete discharge-to-shutdown, followed by a full uninterrupted charge — after that cycle, the gauge tracks the new cell correctly and shutdowns at low percentage stop.

Phone feels warm near the battery compartment on the first charge

A new Li-ion cell arrives from storage with higher internal impedance than a broken-in cell. The SPV E200's charge IC pushes its standard charge current into that higher-impedance cell, which generates slightly more heat than normal during the first cycle. This is not a fault — impedance drops after the first full cycle and heat returns to normal levels. If warmth continues past the second full charge, check that the battery contacts are clean and making firm connection, as a high-contact-resistance fit amplifies the same effect.
