Keep your ZTE smartphone running throughout the day with this Li3844T45P8h896546 4520mAh replacement battery. Compatible with ZTE Blade V40s (released October 2022, 6.67-inch AMOLED display, Unisoc T618 processor, 50MP triple camera) and ZTE Axon 40 SE (released October 2022, 6.67-inch AMOLED display, Unisoc T618 processor, 4GB RAM, 128GB storage, Android 12, MyOS 12). Both devices support 22.5W fast charging via USB Type-C. This Li-Polymer battery delivers the factory-rated 4520mAh capacity for reliable daily use. For reference, third‑party retailers sell this battery for approximately $18 to $30.
Built with Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. With a cycle life of 500+ full charge cycles, this replacement battery is designed for long-term durability. The Blade V40s and Axon 40 SE support 22.5W fast charging — a full charge takes approximately 1.5 to 2 hours. The battery is not user‑replaceable — professional installation is strongly recommended as the phone has a sealed back cover with strong adhesive.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with ZTE Blade V40s and ZTE Axon 40 SE only. The phones have no official IP water resistance rating, 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 22.5W fast charging performance, use the original ZTE 22.5W charger that came with your phone. If you don’t use the device for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

🔋 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.
