TLi013CA Alcatel OneTouch 3082X Compatible Battery 3.7V 1350mAh

Alcatel OneTouch 3082X / OT-3082 — 3.7V Li-ion Replacement Battery (TLi013CA)

This is a 3.7V, 1350mAh Li-ion replacement battery for the Alcatel OneTouch 3082X and OT-3082 smartphones. It carries OEM part number TLi013CA and matches the original cell's physical footprint at 57.80 × 42.70 × 4.70mm. Swap it in when the original cell no longer holds a charge or causes unexpected shutdowns.

• OneTouch 3082X and OT-3082 fit: Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — this cell covers both without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the 3082X platform. The BMS negotiated charge termination correctly and held voltage above 3.5V under screen and modem load without triggering early cutoff.
• Fuel gauge recalibration on first use: On first installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before the charge controller pushes higher current into an uncalibrated cell.

Sudden shutdown at 20–30% on the 3082X after a cell swap

The 3082X fuel gauge IC retains the discharge curve from the old, degraded cell. When the new cell hits a voltage point the IC associates with near-empty, it triggers a protective shutdown — even though actual charge remains. This is not a fault in the replacement cell. Run one full discharge to auto-shutoff followed by a complete charge without interruption, and the coulomb counter will re-anchor to the new cell's actual capacity. After that cycle, reported percentage and real charge level align.

Phone warm near the battery compartment during first few charges

A new Li-ion cell has slightly higher internal impedance than a broken-in cell. During the first one to three charge cycles, the charge IC dissipates more energy as heat while current flows into higher resistance — this is normal and temporary. If the phone feels hot rather than warm, or heat continues past the third full charge, check that the charge IC has not locked into fast-charge mode against an uncalibrated cell. Force a standard 5V/1A charge session and monitor whether temperature drops.
