LG 320 Replacement Battery LGLI-ATL 3.7V 1200mAh

LG 320 / 2300 Series — 3.7V Li-ion Replacement Battery (LGLI-ATL)

This is a 3.7V, 1200mAh Li-ion cell replacing OEM part LGLI-ATL. It fits the LG 320, 2300, 232, and 333 smartphones, along with three additional models in the same family. Voltage and connector match the original spec directly.

• LG 320 / 2300 family compatibility: These models share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS communication protocol is identical across the group, so the cell registers correctly with the phone's charge IC without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an LG 320 unit. The BMS accepted the cell on first insertion, charge current stepped correctly through CC/CV phases, and the protection circuit tripped cleanly at the low-voltage cutoff threshold.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — preventing erratic percentage readings early on.

Sudden shutdown at 20–30% on the LG 320 after a cell swap

The LG 320's fuel gauge IC holds a discharge curve model from the old, degraded cell. When a fresh cell is installed, the IC underestimates remaining charge and miscalculates the voltage cliff. Under peak modem or screen load, the phone's reported percentage does not reflect actual cell state, and the device shuts down before the gauge reaches zero. One full discharge-charge cycle without fast charging forces the coulomb counter to resync against the new cell's actual capacity. After that cycle, shutdowns at false low percentages stop.

LG 320 not powering on after the replacement cell sat in storage

Li-ion cells self-discharge in storage. If the LGLI-ATL cell dropped below approximately 2.5V per cell during shipping or warehousing, the BMS enters a lockout state and blocks all charge current to prevent plating. The phone shows nothing — no charging indicator, no boot. Connect to a wall charger rated at 5V/1A and leave it undisturbed for 15–20 minutes; the BMS uses a trickle pre-charge path to recover the cell to a safe voltage before normal charging resumes. If the LED does not respond within 30 minutes, the cell voltage may be unrecoverable.
