TLP024C1 Alcatel One Touch Shine Lite Replacement Battery 3.85V 2400mAh

Alcatel One Touch Shine Lite — 3.85V Li-Polymer Replacement Battery (TLP024C1)

This 3.85V, 2400mAh Li-Polymer battery replaces the original TLP024C1 cell in the Alcatel One Touch Shine Lite and related OT-5080X and OT-5046G variants. It covers the TD-LTE version as well as 33 additional OT-series models sharing the same battery bay and connector. Physical dimensions are 70.95 × 56.70 × 3.40mm — verify these against your existing cell before fitting.

• One Touch Shine Lite series compatibility: The OT-5080X, OT-5046G, and TD-LTE variant all use the same 3.85V rail, identical flex connector orientation, and share the same BMS handshake protocol. Part numbers TLP024CJ, TLP024C2, TLP024CC, and CAC2400011C1 are interchangeable OEM references for the same physical cell.
• Bench tested on actual hardware: We cycled this cell through charge and full discharge on the OT-5080X platform. The BMS accepted the charge IC handshake immediately, cutoff triggered correctly at the low-voltage threshold, and no overcurrent events were logged during the discharge run.
• Fuel gauge recalibration on first use: Disable fast charging for the first complete discharge-charge cycle after fitting this battery. The fuel gauge IC on these Alcatel devices calibrates its coulomb counter against the cell's discharge curve on that first cycle — running fast charge before calibration completes pushes high current into an uncalibrated cell and skews percentage readings for weeks.

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

This is a voltage cliff issue, not a capacity problem. When the modem fires a transmission burst or the screen ramps brightness, current draw spikes sharply. If the fuel gauge IC is still calibrated to the old cell's discharge curve, it reports 25% remaining while the new cell's actual terminal voltage has already dropped below the shutdown threshold under that load. The phone cuts power to protect the hardware. Run one full discharge to near-zero, then a full uninterrupted charge — this lets the coulomb counter remap to the new cell. After that cycle, the shutdown threshold should align with the percentage readout at roughly 3.50V under load.

Phone stays warm near the battery compartment during the first few charges

A new Li-Polymer cell has higher internal impedance than a worn cell — the charge IC on the Shine Lite compensates by running at a slightly elevated current, which generates more heat at the cell surface. This is normal for the first two to three cycles as the electrolyte conditions and impedance drops. If the warmth is concentrated at the top edge of the phone near the USB port rather than the battery bay, that points to a charge IC or cable issue instead. Monitor with the back cover removed on the first charge and confirm heat is localised to the battery footprint, not the board.
