LG VS995 Replacement Battery BL-44E1F 3.85V 3200mAh

LG V20 / VS995 Series — 3.85V Li-ion Replacement Battery (BL-44E1F)

This is a 3200mAh, 3.85V Li-ion cell built to the BL-44E1F specification. It fits the LG V20, VS995, H990ds, US996, and 22 additional models that share the same removable battery bay and BMS handshake protocol. Capacity is 12.32Wh — confirmed from product data, not estimated.

• V20 / VS995 platform compatibility: These models run the same battery bay dimensions (81.90 × 60.80 × 4.20mm), the same 3.85V nominal rail, and the same BMS communication lines. A cell built to BL-44E1F spec fits all of them without connector modification or firmware changes.
• Bench tested on actual hardware: We cycled this cell on a VS995 unit. The BMS accepted the new cell on first insertion, charge current stepped correctly through CC/CV phases, and the protection circuit tripped at the expected low-voltage cutoff under a sustained screen-on load test.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard current. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes amperage into an uncalibrated coulomb counter.

Sudden shutdown at 20–30% on the VS995 after a cell swap

The VS995's fuel gauge IC was calibrated to the discharge curve of your original, degraded cell. When a fresh 3200mAh cell is installed, the IC still references the old curve. Under modem load or screen brightness spikes, the new cell's actual terminal voltage drops faster than the IC expects at that reported percentage, triggering a low-voltage shutdown. This is not a cell defect — it is a calibration mismatch. Run one full discharge to 3.0V under normal use, then charge to 100% without interruption. After that cycle, the coulomb counter resets against the new cell's actual capacity.

USB fast charge not activating after BL-44E1F installation

On the first charge cycle after a cell swap, the V20's charge IC may stay in trickle or standard mode rather than switching to Qualcomm Quick Charge. The charge IC uses BMS handshake data to confirm cell state before allowing high current — a new cell with no charge history can cause the IC to default to a conservative profile. This usually self-corrects after the first full charge cycle completes. If fast charging still does not activate after cycle two, confirm the charger delivers at least 9V/1.67A and the cable supports the current load — the issue is more often the cable than the cell.
