Alcatel OT-5007S TLP034G1 Compatible Battery 3.85V 3200mAh

Alcatel OT-5007S — 3.85V Li-Polymer Replacement Battery (TLP034G1)

This is a 3.85V, 3200mAh Li-Polymer cell built to replace the original TLP034G1 in the Alcatel OT-5007S smartphone. It fits the OneTouch Pop S series and restores power to a phone that no longer holds charge or fails to turn on. Capacity matches the factory spec at 12.32Wh.

• OT-5007S fit: The TLP034G1 uses a specific connector pitch and cell thickness of 4.40mm. Swapping to a cell outside those dimensions stresses the rear cover and can misalign the flex connector, causing intermittent contact faults.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the OT-5007S platform. The BMS accepted the charge handshake without error flags, and voltage held stable across typical screen-on and modem-active loads.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one full discharge-to-charge cycle. The fuel gauge IC is still calibrated to the old cell's discharge curve — skipping this step causes the percentage readout to drift or jump erratically before it corrects itself.

Sudden shutdown at 20–30% on the OT-5007S after a cell swap

This happens because the phone's fuel gauge IC learned the voltage-to-capacity curve of the old, degraded cell. When the new cell hits a voltage point that the old curve mapped to 20–30%, the phone interprets it as critically low and shuts down — even though real capacity remains. The fix is one complete discharge cycle without interruption, letting the coulomb counter relearn the curve from a known empty state. After that cycle, shutdowns at false percentages stop.

Phone warm near the battery compartment during the first few charges

A new Li-Polymer cell has higher internal impedance than a cell that has been cycled. During the first few charges, the charge IC works against that higher impedance, which generates more heat than you'd expect on a used cell. This is temporary — impedance drops as the cell is cycled, and heat normalises within three to five charges. If the phone feels hot to the touch rather than warm, check that the replacement cell connector is fully seated at 3.3–3.4V rest voltage before charging again.
