Revitalize your Oppo Find X3 Pro with this BLP831 4500mAh replacement battery. Released in March 2021, the Find X3 Pro features a 6.7‑inch 120Hz QHD+ AMOLED display, Snapdragon 888 processor, and groundbreaking 65W SuperVOOC 2.0 fast charging. This Li‑Polymer battery uses an advanced dual‑cell design (two 3.87V cells connected in series to achieve 7.74V output) to deliver the factory‑rated 4500mAh capacity for all‑day usage[reference:10][reference:11].
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. When paired with the original 65W SuperVOOC 2.0 charger, the Find X3 Pro can charge from 0% to 40% in just 10 minutes[reference:12]. Professional installation is recommended as the phone has a sealed back cover with strong adhesive. For reference, third‑party retailers sell this battery for approximately $26 to $32.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BLP831. This battery is compatible with Oppo Find X3 Pro (models CPH2173, PEEM00, OPG03) and Oppo Find X3 (PEDM00). Please also check the battery voltage — our battery matches the OEM dual‑cell design[reference:13][reference:14].
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 65W fast charging performance, use the original SuperVOOC charger and 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.

🔋 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.
