Gionee GN600 Compatible Battery BL-G016 3.7V 1100mAh

GIONEE GN600 / GN868 Series — 3.7V Li-ion Replacement Battery (BL-G016)

This is a 3.7V 1100mAh Li-ion cell replacing part number BL-G016 in the GIONEE GN600, GN868, and GN868H smartphones. It fits all three models because they share the same battery bay dimensions, connector pinout, and charge IC handshake. Capacity is 1100mAh (4.07Wh) — matched to the original specification.

• GN600, GN868, GN868H fit: All three models run the same voltage rail and use an identical BL-G016 footprint — 58.93 × 46.05 × 5.23 mm. The connector and BMS handshake are electrically identical across the range, so one cell covers all three variants without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench, monitoring BMS cutoff thresholds and charge IC acceptance. The protection circuit trips correctly at the low-voltage floor and the charge IC recognised the cell without rejecting it on first connect.
• Fuel gauge recalibration on first use: After installation, disable any fast-charge mode and run one complete discharge-to-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging begins on an uncalibrated reference.

Sudden shutdown at 20–30% on the GN600 after a cell swap

This is a voltage cliff problem, not a capacity problem. When the modem fires a transmission burst or the screen hits full brightness, current draw spikes sharply. A new cell the fuel gauge IC hasn't yet characterised can drop below the BMS low-voltage cutoff under that load even while the reported percentage still looks healthy. The phone shuts off to protect the cell. Run one full discharge cycle — drain to automatic shutdown, then charge uninterrupted to 100% — so the coulomb counter builds an accurate internal model of the new cell before load spikes occur.

Phone reads 100% immediately after installation without charging

The fuel gauge IC retains the charge map from the old cell in its registers. When a new cell connects, the IC reads open-circuit voltage and maps it to the old curve — so a partially charged new cell can report a false full charge. This is a calibration state issue, not a fault with the replacement cell. Drain the phone completely until it shuts off automatically, then charge to 100% in a single uninterrupted session. After that cycle the reported percentage will track the actual cell state of charge accurately.
