About this replacement
Samsung Galaxy Note 10 Lite — 3.85V Li-Polymer Replacement Battery (EB-BN770ABY)
This is a 3.85V, 4300mAh (16.56Wh) lithium-polymer replacement battery for the Samsung Galaxy Note 10 Lite, including SM-N770F/DSM and SM-N770F/DS variants. It replaces OEM part EB-BN770ABY and fits the original battery slot without modification. The cell matches the voltage rail and connector pinout the Note 10 Lite's charge IC expects.
- SM-N770F platform fit: The SM-N770F/DS and SM-N770F/DSM share the same battery bay geometry, connector, and BMS handshake requirements. Both pull from the same 3.85V nominal rail, so one cell covers the full variant range without hardware differences.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an SM-N770F unit. The BMS accepted the cell without faults, fast charge negotiation triggered correctly after the first full cycle, and the charge IC reached cutoff at the expected 4.35V ceiling.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. This gives the fuel gauge IC a clean reference curve for the new cell before high-current charging pushes current into an uncalibrated state.
Sudden shutdown at 20–30% on the replacement cell
A new cell has a slightly different discharge curve than the aged cell the fuel gauge IC was trained on. When the modem fires or the screen peaks in brightness, the phone draws a surge of current. If the IC's stored curve maps that load to a safe voltage but the actual cell voltage dips below the cutoff threshold, the phone shuts down before the gauge reaches zero. This is a calibration gap, not a faulty battery. One full discharge-to-charge cycle with fast charging off resets the coulomb counter and aligns the IC to the new cell's actual curve.
USB-PD fast charge not triggering after installation
On the first cycle after a cell swap, the charge IC may not complete USB-PD handshake negotiation until the BMS has gone through one standard-rate charge. The phone charges but stays at 5W instead of stepping up to 25W. Connect to the original Samsung charger and let the first charge run to 100% at whatever rate the phone accepts. On the second charge, fast charging typically engages at the correct wattage without any settings change.
