About this replacement
Samsung Galaxy A5 2016 Duos — 3.85V Li-ion Replacement Battery (EB-BA510ABE)
This is a 3.85V, 2000mAh Li-ion replacement cell for the Samsung Galaxy A5 2016 Duos and its SM-A510 variants, including SM-A510F, SM-A510F/DS, and SM-A510Y/DS. It matches the OEM part number EB-BA510ABE (also catalogued as GH43-04563A) and fits the physical cavity at 94.80 × 42.00 × 4.40 mm. If your original cell no longer holds charge through a standard day, this is the direct swap.
- SM-A510 variant coverage: All SM-A510 models — single SIM, DS Duos, and regional variants — share the same battery bay dimensions, connector pinout, and 3.85V nominal rail. One cell fits the entire range because Samsung kept the hardware chassis consistent across those SKUs.
- Bench tested on actual hardware: We ran this cell on an SM-A510F and monitored BMS handshake, charge IC acceptance, and NTC thermistor response across three full cycles. The BMS accepted charge from cycle one with no rejection flags, and the protection circuit tripped correctly at over-discharge threshold.
- Fuel gauge recalibration after installation: On first use, disable fast charging and run one complete discharge down to automatic shutdown, then charge uninterrupted to 100%. The Galaxy A5's fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve during this cycle — skipping it causes percentage drift and early shutdown warnings on the replacement cell.
Why the Galaxy A5 2016 reports wrong battery percentage after a cell swap
The SM-A510 uses a fuel gauge IC that builds its state-of-charge model from the original cell's impedance and discharge curve. When a new cell goes in, the IC is still referencing the old cell's data. This mismatch causes the reported percentage to run ahead of or behind real capacity — you may see 30% drop to 5% with no warning. One full uninterrupted discharge-charge cycle forces the coulomb counter to relearn the new cell's characteristics. After that cycle, percentage reporting stabilises.
Sudden shutdown at 20–25% on the replacement cell
This happens when the cell's actual voltage drops below the SoC the fuel gauge thinks it's at — the phone shuts down before the percentage reaches zero. It's a voltage cliff: under modem, screen, or dual-SIM load, the cell cannot sustain voltage and the protection circuit cuts power to prevent damage. It's most visible on DS Duos models where both SIM slots are active simultaneously. Run the fuel gauge recalibration cycle described above, and confirm the cell rests at approximately 3.85V open-circuit after a full charge.
