Orange SPV E100 Compatible Battery PC26A 3.7V 1150mAh

Orange SPV E100 — 3.7V Li-ion Replacement Battery (PC26A)

This is a 3.7V 1150mAh Li-ion battery for the Orange SPV E100 smartphone. It matches the original PC26A part number and restores power to the handset when the stock cell has degraded. Voltage, connector, and form factor align with the SPV E100's power rails.

• SPV E100 platform fit: The E100 runs a single-cell 3.7V Li-ion architecture with a basic protection circuit. This cell matches that voltage rail and uses the same connector pinout, so the phone's charge IC can communicate with the BMS without modification.
• Bench tested on actual hardware: We cycled the cell through charge and discharge under simulated call and screen load. The BMS held cutoff correctly at both ends — no false low-voltage trips and no overcharge events above 4.2V.
• Fuel gauge recalibration on first use: On first installation, run one full discharge down to auto-shutdown then charge uninterrupted to 100%. The SPV E100's fuel gauge IC was calibrated to the original cell's discharge curve — one complete cycle resets that reference point against the new cell.

Why the SPV E100 reports wrong battery percentage after a cell swap

The E100 uses a fuel gauge IC that tracks charge state by learning the discharge curve of the installed cell. When the cell changes, the IC still applies the old curve, so the percentage reading drifts. This is most visible mid-charge, where the display may jump from 60% to 90% without explanation. One full discharge-to-shutdown followed by an uninterrupted charge to 100% forces the IC to recalculate its reference points. After that cycle, percentage readings track accurately against the new cell's actual capacity.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under load — specifically during a call or screen-on state — before the displayed percentage suggests it should. The fuel gauge IC has not yet mapped the new cell's voltage-to-capacity curve, so it misses the real voltage cliff. Under modem load, the cell momentarily dips below the BMS cutoff threshold even though the gauge still shows charge remaining. Run one full cycle first; after recalibration, the gauge will report the low-voltage region accurately and shutdowns move to below 5%.
