🔋 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 Redmi smartphone with this BP47 4500mAh replacement battery. Compatible with Redmi Note 11 Pro+ (released October 2021, featuring a 6.67-inch 120Hz AMOLED display, MediaTek Dimensity 920 processor) and Redmi Note 11 Pro (Snapdragon 695 version). Both devices feature an industry-leading 120W HyperCharge technology — the fastest charging solution in its class at launch. This Li-Polymer battery uses an advanced dual‑cell series design (two 2250mAh/3.87V cells connected in series to achieve 7.74V output) to deliver the factory‑rated 4500mAh capacity. For reference, third‑party retailers sell this battery for approximately $26 to $66.
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. When paired with the original 120W HyperCharge charger and cable, the Redmi Note 11 Pro+ can charge from 0% to 100% in just 15 minutes under Boost mode — a game‑changing feature that eliminates overnight charging. The BP47 battery features integrated dual‑cell BMS (Battery Management System) protecting against overload, short circuit, and over‑temperature, ensuring safe and reliable performance.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BP47. The BP47 battery is the 4500mAh dual‑cell battery with 120W HyperCharge support, while the standard Redmi Note 11 Pro (non‑Plus) with 5160mAh uses BM5A. Professional installation is strongly recommended as the phone has a sealed design with strong adhesive.
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 120W HyperCharge performance, use only the original 120W charger and 6A‑rated cable 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.

Frequently Asked Questions

The BP47 battery for Redmi Note 11 Pro+ is compatible with Redmi Note 11 Pro+ 5G (models 21091116UC, 21091116UG), Redmi Note 11 Pro 5G, Redmi Note 11i, Xiaomi 11i 5G, and Redmi Note 11E Pro. The Redmi Note 11 Pro+ was released in October 2021 featuring a 6.67-inch 120Hz AMOLED display and MediaTek Dimensity 920 processor. This 4500mAh dual-cell battery for Redmi Note 11 Pro+ 21091116UC is a direct replacement for the original BP47 battery. Important: The BP47 is a 4500mAh dual-cell battery with 7.74V output designed for 120W HyperCharge — the standard Redmi Note 11 Pro uses BM5A (5160mAh single‑cell) and is NOT compatible. If your battery replacement is needed because the phone drains quickly or won't hold a charge, this is the correct battery for the Pro+ version. Please verify your device model and check the battery model BP47 printed on your existing battery before purchasing.

The BP47 4500mAh 7.74V battery has a total capacity of 4500mAh (17.4Wh). It is a dual‑cell Li-Polymer battery — two 2250mAh/3.87V single cells connected in series, achieving a combined output voltage of 7.74V (3.87V × 2). Single‑cell charge limit voltage is 4.45V. The battery is CE, RoHS, and UN38.3 certified and built with Grade A cells. The Redmi Note 11 Pro+ supports 120W HyperCharge — when paired with the original 120W charger and 6A-rated cable, the phone can charge from 0% to 100% in just 15 minutes under Boost mode. This makes it one of the fastest-charging smartphones ever released. For best results, always use the original 120W charger that came with your phone — using other chargers will not achieve the same fast charging speed and may damage the battery.

Professional installation is strongly recommended for Redmi Note 11 Pro+ battery installation. The Redmi Note 11 Pro+ has a sealed design with a glass back cover secured by strong adhesive. The process to replace BP47 battery in Redmi Note 11 Pro+ requires heating to soften adhesive and careful prying to avoid damaging the display or back cover — the phone has a highly curved glass back that requires extra caution. 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 internal components, and never reuse a battery after removal. Third-party repair shops typically charge $20-40 for labor.
