About this replacement
Samsung Galaxy On5 2016 Duos — 3.85V Li-Polymer Replacement Battery (EB-BG570ABE)
This is a 3.85V, 2600mAh Li-Polymer battery that replaces the original EB-BG570ABE cell in the Samsung Galaxy On5 2016 Duos. It fits the SM-G5700, Galaxy On5 2016 Duos TD-LTE, and Galaxy On5 Neo 2016, among other variants in this family. Same voltage, same connector, same BMS handshake as the factory cell.
- SM-G5700 and On5 Neo 2016 compatibility: These variants share the same 3.85V power rail, physical connector layout, and BMS communication protocol. One cell covers the full lineup without modification.
- Bench tested on actual hardware: We cycled this cell through a full discharge-charge sequence on a Galaxy On5 2016 unit. The BMS accepted the new cell without error flags, and the charge IC stepped through trickle, constant-current, and constant-voltage phases cleanly.
- Fuel gauge recalibration on first cycle: After installing this battery, run one complete discharge down to auto-shutoff, then charge uninterrupted to 100% with fast charging disabled. The fuel gauge IC needs this cycle to map the new cell's discharge curve — skipping it causes erratic percentage readings for the first several days of use.
Sudden shutdown at 20–30% on the Galaxy On5 2016 after a cell swap
A new Li-Polymer cell has a slightly different voltage-versus-capacity curve than the worn cell the fuel gauge IC was originally calibrated against. When the modem fires up for a call or the screen brightness peaks, current draw spikes and the cell voltage drops sharply. The fuel gauge IC sees that voltage drop, compares it against the old curve, and the device cuts out — even though actual charge remains. One full discharge-charge cycle with fast charging off forces the coulomb counter to relearn the new curve, and shutdowns at 20–30% stop.
Device will not power on after the replacement battery sat in storage
Li-Polymer cells self-discharge during storage. If this battery sat below approximately 2.5V per cell, the BMS enters a protective lockout and blocks normal charge current to prevent thermal runaway on an over-discharged cell. The phone appears completely dead — no boot, no charge indicator. Connect the device to a charger and leave it untouched for 20–30 minutes; the charge IC delivers a low trickle current that brings the cell voltage back above the BMS recovery threshold, typically around 2.9V, before normal charging resumes.
