🔋 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.

Restore the battery life of your Oppo smartphone with this BLP609 2850mAh replacement battery. Compatible with Oppo R9 (released March 2016, featuring a 5.5-inch AMOLED display, MediaTek Helio P10 octa-core processor, and 4GB RAM), Oppo R9m, Oppo R9mt, and Oppo F1 Plus (X9009, X9079). For reference, third‑party retailers sell this battery for approximately $18 to $25.
The Oppo R9 supports Oppo‘s patented VOOC Flash Charge technology — users can reach 75% of the 2850mAh battery’s capacity after just 30 minutes of charging using the original 20W (5V/4A) VOOC charger[reference:0]. This Li-Polymer battery delivers the factory-rated 2850mAh 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, RoHS, and UN38.3 certified for safe transport and use.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BLP609. This battery is compatible with Oppo R9 (R9m, R9mt, R9km) and Oppo F1 Plus (X9009, X9079). Professional installation is recommended as the phone has a sealed back cover with strong adhesive. 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 VOOC Flash Charge performance, use the original 5V/4A charger 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.
