CAB31Y0014C2 Cricket Authority Replacement Battery 3.7V 1750mAh

Cricket Authority — 3.7V Li-ion Replacement Battery (CAB31Y0014C2)

This 3.7V, 1750mAh Li-ion cell replaces the original battery in the Cricket Authority smartphone. It matches OEM part numbers CAB31Y0014C2 and TLiB31Y exactly. Capacity is 1750mAh (6.48Wh) — taken from the product specification, not extrapolated.

• Cricket Authority compatibility: The Authority uses a single-cell 3.7V nominal Li-ion pack with a fixed connector pinout and BMS handshake tied to the CAB31Y0014C2 part number. Cells outside that voltage range will not initialise correctly with the device's charge IC.
• Bench tested on actual hardware: We cycled this cell through charge and load on the Authority platform. The BMS accepted the charge IC handshake on the first connection, and the protection circuit tripped correctly at the low-voltage cutoff threshold — no unexpected shutoffs mid-cycle.
• Fuel gauge recalibration on first use: On first installation, disable fast charging and run one full discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's actual discharge curve before reporting percentage to the OS — skipping this step is the primary cause of erratic percentage readings post-swap.

Sudden shutdown at 20–30% on the Cricket Authority after a battery swap

This is a voltage cliff issue, not a capacity problem. Under peak load — modem transmit bursts or screen brightness spikes — the new cell's internal resistance causes voltage to sag below the BMS cutoff threshold even when the fuel gauge still reads 20–30%. The protection circuit interprets this voltage sag as a low-cell event and shuts the device down. One full calibration cycle at standard charge rate corrects the fuel gauge IC's reference curve, and the reported percentage will then align with the actual usable voltage window.

Phone not powering on after the replacement cell sat in storage

Li-ion cells self-discharge during storage. If the cell dropped below approximately 2.5V per cell, the BMS enters a lockout state to prevent damage from deep discharge. The phone will show no response — not even a charging indicator — when connected to power. Connect to a wall charger (not a PC USB port, which may not supply enough current) and leave it for 20–30 minutes without pressing any buttons. Once the BMS detects voltage recovery above its wake threshold, the charge IC will resume normal operation and the screen will respond.
