CAB32A0001C1 Alcatel OT-918 Mix Replacement Battery 3.7V 1500mAh

Alcatel OT-918 Mix — 3.7V Li-ion Replacement Battery (CAB32A0001C1)

This 3.7V, 1500mAh Li-ion cell replaces part number CAB32A0001C1 in the Alcatel OT-918 Mix and One Touch 918 Mix smartphones, as well as the EE40 and EE40VB variants. It matches the original cell's dimensions at 51.61 x 50.72 x 5.24mm and drops into the same battery bay without modification. Voltage and capacity match factory spec exactly.

• OT-918 Mix and EE40 platform compatibility: The OT-918 Mix and EE40 variants share the same battery bay geometry, connector pinout, and BMS handshake protocol — all four models accept the CAB32A0001C1 cell without any hardware changes.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an OT-918 Mix unit. The BMS accepted the cell on first insertion, thermal behaviour stayed within normal range throughout charging, and the fuel gauge IC initialised without errors.
• Fuel gauge recalibration on first use: After installing a new cell, disable fast charging and run one full discharge-charge cycle at standard rate. This gives the fuel gauge IC a clean discharge curve from the new cell before high-current charging pushes current into an uncalibrated state.

Sudden shutdown at 20–30% on a freshly installed cell

A new cell carries a different internal resistance profile than the worn cell the fuel gauge IC was calibrated against. When the modem or display draws a high current burst, the cell voltage can sag below the BMS cutoff threshold even though the reported percentage still shows charge remaining. The phone shuts off because the BMS sees a real undervoltage event at the terminals — not because the cell is defective. One full discharge-charge cycle at standard rate recalibrates the coulomb counter and eliminates the false cutoff; target a resting voltage of 4.18–4.20V at the top of that first charge before resuming normal use.

Device won't power on after the replacement cell sat in storage

Li-ion cells self-discharge during storage, and the OT-918 Mix BMS locks out completely when cell voltage drops below approximately 2.5V. In lockout, the phone shows no charge indicator and will not boot — it looks dead even when connected to a charger. Connect the phone to a known-good wall adapter and leave it without interruption for 20–30 minutes; the charge IC trickle-charges the cell up through the lockout threshold before the BMS re-engages. Once the battery icon appears on screen, normal charging resumes automatically.
