Cricket AUTHORITY CAB31Y0014C2 Replacement Battery 3.7V 1500mAh

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

This is a 3.7V, 1500mAh Li-ion replacement battery for the Cricket Authority smartphone. It replaces OEM part numbers CAB31Y0014C2 and TLiB31Y. Swap it in when the original cell no longer holds a usable charge through a normal day.

• Cricket Authority fit: The Authority uses a removable back cover and a fixed connector pinout tied to this cell's voltage rail. The BMS in this replacement matches the original charge termination voltage and current limits, so the phone's charge IC accepts it without throwing a fault.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Authority platform. The BMS held cutoff at the correct low-voltage threshold and accepted a full charge without interruption at the standard charge rate.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle before enabling it. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated gauge.

Why the Cricket Authority shuts down suddenly at 20–30% after a cell swap

The Authority's fuel gauge IC was calibrated to the old cell's discharge curve. A fresh cell has a steeper voltage cliff at the low end, so the gauge reads 25% while the actual cell voltage is already near the BMS cutoff threshold. Under modem or screen load, the cell voltage dips fast, hits the cutoff, and the phone shuts off. One full discharge-charge cycle — draining to automatic shutdown, then charging uninterrupted to 100% — resets the coulomb counter against the new cell. After that cycle, the percentage readings stabilise.

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

Li-ion cells self-discharge in storage. If this battery dropped below roughly 2.5V per cell before installation, the BMS enters lockout mode and blocks current flow to protect the cell. The phone will show nothing — no boot screen, no charge indicator. Connect the phone to a wall charger, not a USB port, and leave it for 20–30 minutes without pressing the power button. The charge IC will trickle current into the cell until it clears the BMS recovery threshold, after which normal charging resumes. If the charge LED does not appear within 45 minutes, check that the battery connector is fully seated.
