✅ 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.

Revitalize your Xiaomi 11T with this BM59 5000mAh replacement battery. Released in September 2021, the Xiaomi 11T features a 6.67-inch 120Hz AMOLED display, MediaTek Dimensity 1200 processor, and supports 67W fast charging — capable of charging from 0% to 100% in just 36 minutes. This Li-Polymer battery delivers the factory-rated 5000mAh capacity for all-day usage. For reference, third‑party retailers sell certified batteries for approximately $18 to $25.
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. Professional installation is strongly recommended as the battery is not user-replaceable.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BM59. This battery is compatible with Xiaomi 11T models 21081111RG, 21081111RI, and 21081111RN. 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 Xiaomi 67W 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.

Please verify your device model in Settings > About Phone and check the battery model BM59 printed on your existing battery before purchasing.

The battery is not user‑replaceable — the official Xiaomi service pack is designed for professional repair. The phone has no official IP water resistance rating, so water seal maintenance is not a concern after replacement. If you choose DIY phone battery replacement, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), use plastic tools to avoid damaging the display or internal components, and never reuse a battery after removal. Third-party repair shops typically charge $15‑30 for labor.
