🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Power up your TCL T508N 5G phone with this TLi028CB 3000mAh replacement battery.

This Li-Polymer battery delivers the factory-rated 3000mAh capacity — perfect for extended use as a 5G mobile hotspot, daily driver, or backup phone. For reference, third‑party retailers sell this battery for approximately $17 to $25.
The battery is user‑replaceable — the T508N features a removable back cover, allowing you to swap batteries without tools. Built with Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, and UN38.3 certified for safe transport and use. With a cycle life of 500+ full charge cycles, this replacement battery is designed for long-term durability.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with Alcatel 5G T508N and TCL T508N (battery models TLi028CB or TLi029CB). The phone has a removable back cover — no special tools required for installation. The device is not water resistant, so water seal maintenance is not a concern after replacement.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best performance, use a standard 5V/2A (10W) USB-C charger. If you don’t use the device for a long time, store the battery in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

Locate the notch at the bottom of the back cover and gently lift it open. Remove the old battery by lifting it out, noting the orientation of the gold-plated contacts. Insert the new TLi028CB battery with the contacts aligned correctly (the contacts should face the corresponding springs inside the compartment). Close the back cover until it snaps securely into place. Charge the phone fully before first use. The phone has no official IP water resistance rating, so no special sealing is required.
