Orange SPV E600 Replacement Battery EXCA160 3.7V 2200mAh

Orange SPV E600 — 3.7V Li-ion Replacement Battery (EXCA160)

This is a 3.7V, 2200mAh Li-ion cell for the Orange SPV E600 smartphone. It replaces OEM part numbers EXCA160 and 35H00080-00M. If the original battery swells, drops capacity sharply, or refuses to hold a charge through a normal day, this cell is the direct swap.

• SPV E600 fit: The E600 uses a fixed connector pinout and BMS handshake tied to this cell format. The 55.82 × 35.90 × 10.11mm dimensions match the battery bay exactly — no modification needed to seat the cell or close the rear cover.
• Bench tested on actual hardware: We cycled this cell through charge and discharge under load conditions matching the E600's modem and display draw. The BMS responded correctly to charge termination and held voltage within expected bounds at both low and high state-of-charge.
• Fuel gauge recalibration on first use: On first use after installation, run one full discharge-to-charge cycle before enabling any high-current charging. This lets the E600's fuel gauge IC map its coulomb counter against the new cell's actual discharge curve — skipping this step causes the percentage readout to track against the old cell's profile.

Why the SPV E600 reports wrong battery percentage after a cell swap

The E600's fuel gauge IC builds a charge model from accumulated cycle data on the original cell. When you fit a new cell, that model still references the old discharge curve. The percentage display will read incorrectly — often showing full charge sooner than actual capacity justifies, or dropping suddenly in the lower range. One complete discharge from 100% down to automatic cutoff, followed by a full charge, forces the IC to reset its coulomb counter against the new cell. After that cycle, the percentage readout stabilises.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops below what the modem or display controller will tolerate under load — even though the fuel gauge still shows charge remaining. A fresh cell has slightly different internal resistance than the aged cell the IC was calibrated to, so voltage sag under high-draw moments hits the hardware cutoff before the software percentage reaches zero. Run the full recalibration cycle described above. If shutdowns persist below 3.6V under load after two full cycles, check that the rear cover is seating the cell contacts firmly — intermittent contact spikes apparent internal resistance.
