GIONEE C500 Replacement Battery BL-C003 3.7V 1750mAh Li-ion

GIONEE C500 / C600 — 3.7V Li-ion Replacement Battery (BL-C003)

This is a 3.7V, 1750mAh Li-ion replacement battery for the GIONEE C500 and C600 smartphones. It uses OEM part number BL-C003 and fits the original battery slot without modification. Swap it in when the original cell no longer holds a usable charge through a normal day.

• C500 and C600 compatibility: Both models share the BL-C003 footprint, connector pinout, and 3.7V nominal voltage rail. The BMS handshake is identical across both devices, so one cell covers either phone without hardware changes.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the C500 platform. The BMS accepted charge without error flags, and protection circuits tripped correctly at the low-voltage cutoff threshold.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging and run one complete discharge-to-charge cycle before switching fast charging back on. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve — without this step, the OS percentage readout can drift by 10–15% within the first week.

Sudden shutdown at 20–30% on the GIONEE C500 after a cell swap

This happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. The new cell has a slightly different voltage-versus-capacity slope, so the gauge reports 25% remaining when the actual cell voltage has already dropped below what the modem and display need to stay on. The phone's hardware protection cuts power before the OS can react. One full discharge cycle — down to automatic shutdown — followed by an uninterrupted charge to 100% resets the coulomb counter and eliminates the false cutoff.

Phone feels warm near the battery during the first few charges

A new cell has higher internal impedance than a broken-in one. During the first two or three charge cycles, the charge IC pushes current into higher resistance, which dissipates more heat at the battery terminals. This is normal and typically drops off after three full cycles as impedance falls. If warmth persists past five cycles or the phone becomes hot to the touch, check that the charge IC is not stuck in fast-charge mode — drop to standard 5V/1A charging and confirm the temperature normalises within one cycle.
