✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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.

Restore the battery life of your Meizu smartphone with this BA813 3100mAh replacement battery. Compatible with Meizu V8 Pro (M813Q, 5.7-inch HD+ display, MediaTek Helio P22 processor, 4GB RAM, 64GB storage) and Meizu M8 (M813H, dual-SIM with microSD expansion).

Built with Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, UL, and ISO9001 certified for safe transport and use. The Meizu V8 Pro supports 10W charging (5V/2A) via micro-USB — a full charge takes approximately 1.5-2 hours. 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 Meizu V8 Pro (M813Q) and Meizu M8 (M813H). The battery is not user‑replaceable — professional installation is strongly recommended as the phone has a sealed back cover with strong adhesive. 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. 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.
