ED30 Motorola Moto G Replacement Battery 3.8V 1800mAh

Motorola Moto G / XT1032 — 3.8V Li-Polymer Replacement Battery (ED30 / SNN5932A)

This 3.8V, 1800mAh Li-Polymer battery replaces the original ED30 / SNN5932A cell in the Motorola Moto G smartphone. It fits the XT1032, T1028, T1028PP, and over a dozen additional Moto G variants. Dimensions are 81.55 × 48.15 × 3.60mm — matching the original footprint for a direct fit.

• Moto G platform compatibility: All listed variants — XT1032, T1028, T1028PP, and the extended Moto G family — share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell on an XT1032 and monitored BMS communication throughout. The charge IC accepted the new cell without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold.
• Fuel gauge recalibration on first install: After fitting this cell, disable fast charging and run one full discharge-charge cycle before normal use. This gives the fuel gauge IC time to map its coulomb counter against the new cell's actual discharge curve — before high-current charging pushes into an uncalibrated state.

Why the Moto G reports wrong battery percentage after a cell swap

The Moto G uses a coulomb-counting fuel gauge IC that builds its capacity model from the original cell's charge and discharge history. When you fit a new cell, that learned model no longer matches the actual discharge curve of the replacement. The IC keeps using the old data, so the percentage shown on screen drifts from reality — often reading higher than actual state of charge. One complete discharge-to-shutdown followed by a full uninterrupted charge resets the reference and brings the percentage readout back into alignment.

Sudden shutdown at 20–30% on the replacement cell

This happens when the modem or display pulls a short burst of high current and the cell voltage drops below the BMS protection threshold — even though the fuel gauge still shows charge remaining. It is a voltage-cliff issue, not a capacity fault. The cell cannot sustain voltage under load at that state of charge until it has been broken in. Run two or three full discharge-charge cycles and the BMS will have a more accurate low-voltage floor to work against. If shutdown continues below 3.4V under load, check that the battery connector is fully seated.
