🔋 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 Oppo Reno 4 Pro with this BLP787 4000mAh replacement battery. The Oppo Reno 4 Pro 5G was released in June 2020, featuring a 6.5-inch 90Hz AMOLED display, Qualcomm Snapdragon 765G processor, and supports 65W SuperVOOC 2.0 fast charging – capable of charging from 0% to 100% in just 36 minutes. This Li-Polymer battery uses an advanced dual‑cell series design – two 2000mAh/3.87V cells connected in series to achieve a combined voltage of 7.74V – delivering the factory-rated 4000mAh capacity for all-day usage.
Built with high-quality Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over‑discharge, short circuit, and overcurrent. CE, FCC, and RoHS certified for safe transport and use. Each battery cell is tested for correct capacity and to ensure all safety requirements are met before installation. With a cycle life of over 500 full charge cycles, this replacement battery is designed for long-term durability. For reference, third-party retailers sell this battery for approximately $20 to $38.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BLP787. This battery is compatible with Oppo Reno 4 Pro 5G (models CPH2089, PDNM00, PDNT00) and Oppo Reno 4 Pro 4G (model CPH2109). Professional installation is recommended as the phone has a sealed glass back cover 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 65W SuperVOOC 2.0 charging performance, use the original Oppo 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.

It is a dual‑cell Li-Polymer battery – two 2000mAh/3.87V single cells connected in series (7.74V = 3.87V × 2). Single‑cell charge limit voltage is 4.45V. The battery is CE, FCC, and RoHS certified and built with Grade A cells.

Professional installation is strongly recommended for Oppo Reno 4 Pro battery replacement. The Oppo Reno 4 Pro has a sealed design with a glass back cover secured by strong adhesive — the phone features a slim 7.6mm ultra-slim body with a crystal‑like glass back. The process to replace BLP787 battery in Oppo Reno 4 Pro CPH2089 requires heating to soften adhesive, careful prying to avoid damaging the display or back cover, and proper resealing with fresh adhesive. 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.
