Orange New York AL-001 Replacement Battery 3.7V 750mAh

Orange New York — 3.7V Li-ion Replacement Battery (AL-001)

This is a 3.7V, 750mAh Li-ion replacement battery for the Orange New York smartphone. It uses OEM part number AL-001 and fits the New York model directly. Install it when the original cell has degraded, swells, or no longer holds a usable charge.

• Orange New York compatibility: The New York uses a single Li-ion cell at 3.7V nominal. This replacement matches that voltage rail and connector pinout. The BMS handshake on the New York is straightforward — no proprietary authentication chip blocks third-party cells.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the New York platform. The BMS accepted the cell cleanly, hit full charge termination at 4.2V, and cutoff triggered correctly at low voltage without tripping a protection lockout.
• First-cycle fuel gauge recalibration: On first use after installation, disable fast charging for one complete discharge-charge cycle. The fuel gauge IC is still calibrated to the old cell's discharge curve. Running one slow cycle lets it rebuild its coulomb-count baseline before higher charge current is applied.

Sudden shutdown at 20–30% on the Orange New York after a cell swap

This is a voltage cliff issue, not a capacity fault. When the modem transmits or the screen brightness peaks, current draw spikes briefly. A new cell with a slightly different internal resistance curve can sag below the BMS cutoff threshold at these load spikes — even when the fuel gauge still shows charge remaining. The phone reads 25% and shuts off because the actual cell voltage dropped below 3.2V under load. Running two full discharge-charge cycles recalibrates the coulomb counter and typically moves the cliff below 10%.

Orange New York reporting incorrect battery percentage after replacement

The fuel gauge IC stores a learned discharge model from the old cell. After a swap, that model no longer matches the new cell's actual voltage-to-capacity curve. The percentage display will read high or jump erratically — commonly 40% dropping to 15% in minutes. Fix this by letting the phone discharge fully until automatic shutdown, then charging uninterrupted to 100% without removing the charger. After one complete cycle, the IC resets its reference points against the new cell.
