BLPA45 Oppo Realme GT Neo6 SE Replacement Battery 7.82V 2650mAh

Oppo Realme GT Neo6 SE — 7.82V Li-Polymer Replacement Battery (BLPA45)

This is a 7.82V, 2650mAh (20.72Wh) Li-Polymer replacement battery for the Realme GT Neo6 SE smartphone. It fits the original BLPA45 cell slot and matches the OEM connector and BMS handshake required by the device. Swap it in when your original cell can no longer hold charge through a full day of normal use.

• Realme GT Neo6 SE fit: The GT Neo6 SE uses a dual-cell Li-Polymer pack at 7.82V nominal — that is two cells in series, not a single 3.7V cell. Any replacement must match this series configuration and the BMS communication protocol. This cell does both.
• Bench tested on actual hardware: We cycled this battery through charge and discharge on the GT Neo6 SE platform. The BMS accepted the cell without fault flags, fast charge engaged on the second cycle, and the fuel gauge IC tracked state-of-charge accurately after one full calibration cycle.
• Fuel gauge recalibration on first use: On first installation, disable fast charging and run one complete discharge down to auto-shutdown, then charge to 100% on standard charge. This gives the coulomb counter a clean reference curve against the new cell before high-current charging is applied to an uncalibrated pack.

Why the GT Neo6 SE reports wrong battery percentage after a cell swap

The fuel gauge IC on the GT Neo6 SE stores a learned discharge curve from the old cell. When you install a new cell, that stored curve no longer matches reality. The gauge reads percentage against the wrong reference, so it may show 30% and cut off, or show 100% before the cell is actually full. One full discharge-to-shutdown followed by a complete standard charge resets the coulomb counter to the new cell's actual capacity. After that cycle, percentage readouts track correctly.

Sudden shutdown at 20–25% on the replacement cell

This is a voltage cliff issue, not a capacity defect. Under high-load conditions — active modem, screen at full brightness, or background sync — the cell voltage drops faster than the fuel gauge expects at that state-of-charge. When cell voltage falls below roughly 3.2V per cell (6.4V total), the BMS triggers a hard cutoff before the OS can gracefully shut down. The fix is to complete the fuel gauge recalibration cycle first: one full discharge to auto-shutdown, then a full charge to 100% on standard current. After calibration, the system cuts load earlier and the cliff shutdown stops.
