About this replacement
Samsung Galaxy A9 Pro 2016 — 3.85V Li-Polymer Replacement Battery (EB-BA910ABE)
This is a 3.85V, 5000mAh Li-Polymer replacement battery carrying OEM part number EB-BA910ABE. It fits the Galaxy A9 Pro 2016, Galaxy A9 Pro 2016 Duos TD-LTE, SM-A910F/DS, and SM-A9100. Swap it in when the original cell degrades, swells, or no longer holds a usable charge.
- SM-A910F/DS and SM-A9100 compatibility: Both variants share the same voltage rail, connector pinout, and BMS handshake protocol — this cell covers both without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the SM-A910F platform. The BMS accepted the charge protocol without cutoff errors, and voltage held stable under simultaneous screen and modem load.
- First-cycle recalibration: On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging is applied to an uncalibrated cell.
Sudden shutdown at 20–30% on the replacement cell
This is a voltage cliff problem, not a capacity problem. A new cell has a steeper discharge curve than the aged cell the fuel gauge IC was calibrated to — at around 20–30% reported charge, the actual cell voltage drops below what the modem and display controller need to sustain operation. The phone shuts down even though the OS still reports charge remaining. One full discharge cycle — draining to automatic shutdown, then charging uninterrupted to 100% — forces the coulomb counter to recalibrate against the new curve and eliminates most false shutdowns.
Phone feels warm near the battery during the first few charges
A fresh Li-Polymer cell has higher internal impedance than a broken-in cell. During the first two or three charge cycles, the charge IC works against that higher impedance, which produces more heat than you'd see on a used cell. This is normal and typically resolves by the third full charge as internal impedance drops. If the phone remains hot to the touch after the third cycle or the case deforms near the battery, stop charging and inspect the cell seating.
