LG 110 CDMA Replacement Battery 3.7V 900mAh Li-ion

LG 110 (CDMA) / 111 / 115 / 210 Series — 3.7V Li-ion Replacement Battery (LGLI-AADL)

This is a 3.7V, 900mAh Li-ion replacement battery for the LG 110 (CDMA) and related CDMA candybar models including the 111, 115, and 210. It matches the OEM LGLI-AADL and LGLI-AADM part numbers. Swap it in when the original cell no longer holds charge or fails to power on.

• LG 110 / 111 / 115 / 210 platform fit: These models share the same 3.7V single-cell architecture, physical form factor, and connector pinout. The BMS on each device communicates over the same ID line, so one cell covers the full model range without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on a LG CDMA platform. The BMS accepted the new cell without flagging a fault, charge termination triggered correctly at 4.2V, and low-voltage cutoff held at the expected threshold.
• Fuel gauge recalibration on first use: After installing this cell, disable any fast-charge mode and run one complete discharge-to-charge cycle before normal use. This lets the fuel gauge IC build an accurate discharge curve against the new cell — skipping this step causes the percentage readout to track the old cell's curve and report incorrect values.

Why the LG 110 reports wrong battery percentage after a cell swap

The LG 110 uses a fuel gauge IC that stores a learned discharge curve from the previous cell. When a new cell goes in, that stored curve no longer matches the actual cell chemistry, so the percentage shown on screen drifts from reality. The gauge needs one full discharge down to automatic cutoff and a complete charge back to 4.2V to relearn the curve. Until that cycle completes, readings can be off by 15–25%. Run that single calibration cycle before relying on the percentage indicator.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under the load of the CDMA radio during a call or data burst — a voltage cliff the fuel gauge did not predict. The BMS trips the protection circuit before the displayed percentage reaches zero, cutting power to protect the cell. It is not a faulty battery; it is the fuel gauge still tracking the old cell's curve. Complete one full calibration cycle as described above, and the shutdown threshold should move back to the correct range near 3.4–3.5V per cell.
