About this replacement
Samsung Galaxy Pocket Neo / Pocket 2 Duos — 3.7V Li-ion Replacement Battery (EB-BG110ABE)
This is a 3.7V, 1250mAh Li-ion cell built to replace the EB-BG110ABE in Samsung Galaxy Pocket Neo and Galaxy Pocket 2 Duos handsets. It fits SM-G110, SM-G110B, SM-G110H, and related variants. Voltage and capacity match OEM spec exactly — no modifications needed to fit the battery compartment.
- SM-G110 series fit: The SM-G110 variants — G110, G110B, and G110H — all run the same 3.7V rail with the EB-BG110ABE footprint. The connector tab placement, BMS pin layout, and cell dimensions (56.53 × 43.00 × 4.55mm) are identical across these models, so one SKU covers the full range.
- Bench tested on actual hardware: We cycled this cell on an SM-G110 unit and monitored BMS handshake at connection. The protection circuit flagged correct voltage on first contact, charge IC accepted the cell without error codes, and the fuel gauge IC began tracking state-of-charge from the first cycle.
- Fuel gauge recalibration on first use: On first installation, disable fast charging if available and run one complete discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before higher charge currents are applied to an uncalibrated cell.
Sudden shutdown at 20–30% on the SM-G110 after a cell swap
This is a voltage cliff issue, not a capacity problem. When the modem transmits or the screen peaks brightness, current draw spikes sharply. A new cell with an uncalibrated fuel gauge IC can report 25% remaining while the actual resting voltage has already dropped near the BMS cutoff threshold of 3.0V. The phone shuts down to protect the cell even though the percentage shown looks fine. One full slow discharge-charge cycle recalibrates the coulomb counter and moves the reported percentage back in line with real voltage.
Phone not powering on after the replacement battery sat in storage
Li-ion cells self-discharge during storage. If the cell voltage dropped below approximately 2.5V, the BMS enters lockout mode and blocks current flow to prevent damage to the cell. The phone will show no sign of life — no charge indicator, no vibration. Connect to a wall charger rather than a PC USB port, which may not supply enough current to wake the BMS. Leave it connected for 15–20 minutes before attempting to power on; the charge IC needs to trickle charge the cell back above 2.8V before normal charging resumes.
