Restore the ultra‑fast charging capability of your Redmi Note 12 Discovery Edition with this BP4H 4300mAh replacement battery. Compatible with the Redmi Note 12 Discovery Edition (model 22101316UP), this dual‑cell Li‑Polymer battery uses a series design — two 2150mAh cells connected in series — to achieve a combined output of 7.74V, delivering the factory‑rated equivalent 4300mAh capacity. The Discovery Edition was released in October 2022 featuring a 6.67‑inch 120Hz AMOLED display, MediaTek Dimensity 1080 processor, and industry‑leading 210W HyperCharge technology — capable of charging from 0% to 66% in just 5 minutes and 0% to 100% in 9 minutes. The phone also features 3 independent 100W charging chips with 98.5% conversion efficiency, 10C high‑rate cells, and X‑axis linear motor. For reference, third‑party retailers sell this battery for approximately $25 to $40.
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. The device supports 210W HyperCharge — when paired with the original Xiaomi 210W charger (20V/10.5A) and 10.5A‑rated USB‑C cable, the 4300mAh battery can be fully charged in approximately 9 minutes (official specification). Professional installation is strongly recommended as the battery is not user‑replaceable — the phone has a sealed back cover with strong adhesive. The phone has no official IP water resistance rating, so water seal maintenance is not a concern after replacement.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BP4H. This battery is compatible with Redmi Note 12 Discovery Edition (22101316UP) only — NOT compatible with Redmi Note 12 Pro or standard Note 12 models. The battery is not user‑replaceable — 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 210W HyperCharge performance, use the original Xiaomi 210W charger (20V/10.5A) and 10.5A‑rated cable 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.
