🔋 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.

Revitalize your Xiaomi Mi Max with this BM49 4850mAh replacement battery. Released in May 2016, the Xiaomi Mi Max features a massive 6.44-inch Full HD display, Snapdragon 650/652 processor, and originally came with a 4850mAh high-capacity battery — one of the largest in its class at the time. This Li-Polymer battery delivers the factory-rated 4850mAh capacity for all-day usage, allowing you to enjoy extended browsing, video streaming, and gaming without constantly searching for a charger. For reference, third-party retailers sell this battery for approximately $15 to $24.
Built with high-quality 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. The battery supports 5V/2A (10W) standard charging via micro-USB, and features a cycle life of over 500 charges while maintaining 80% capacity. The built-in protection chip ensures safe operation and helps extend overall battery lifespan. For reference, third-party retailers sell this battery for approximately $15 to $24.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BM49. This battery is compatible with Xiaomi Mi Max models 2016001, 2016002, 2016007, as well as Dual SIM variants. Professional installation is recommended as the Mi Max has a sealed back cover with strong adhesive. The phone 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 results, use the original 5V/2A charger that came with your phone. If you don’t use the battery 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.
