🔋 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 gaming smartphone with this BM56 5065mAh replacement battery. Compatible with Xiaomi Poco F3 GT (released July 2021, featuring a 6.67-inch 120Hz AMOLED display, MediaTek Dimensity 1200 chipset with 9-core GPU, dual magnetic gaming triggers, and 64MP AI triple camera) and Xiaomi Redmi K40 Gaming Edition. This Li-Polymer battery delivers the factory-rated 5065mAh capacity, offering exceptional all-day power for extended gaming sessions, streaming, and daily tasks without constantly reaching for a charger. For reference, third-party retailers sell this battery for approximately $20 to $38.
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 BM56 battery supports 67W fast charging technology — official specifications from Xiaomi indicate a 67W fast charger is included in the box, capable of charging the device significantly faster than standard chargers. With a cycle life of over 500 full charge cycles, this battery is designed for long-term durability.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BM56. This battery is compatible with Xiaomi Poco F3 GT (M2104K10I) and Xiaomi Redmi K40 Gaming (M2012K10C, M2104K10AC). This battery is NOT compatible with standard Redmi K40 (which uses a 4520mAh battery, model BM4Y) — only the Gaming Edition models use BM56. Professional installation is recommended as the phone has a sealed glass 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 67W fast charging performance, use the original 67W 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.
