🔋 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 BLP689 3600mAh replacement battery. Compatible with Oppo R15x (released September 2018, featuring a 6.4-inch AMOLED waterdrop display, Snapdragon 660 processor, 6GB RAM, and 128GB storage, with a sleek 3D glass back and gradient design), Oppo RX17 Neo (also known as R17 Neo, CPH1893), and Oppo K1 (PBCM10, PBCM30). These devices feature a 3600mAh battery supporting 10W VOOC flash charging technology — delivering reliable all-day power for calls, browsing, and media playback.
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. The 10W VOOC fast charging capability allows the compatible phones to charge quickly when paired with the original Oppo charger. For reference, third-party retailers sell this battery for approximately $22 to $34.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BLP689. This battery is compatible with Oppo R15x, Oppo RX17 Neo (R17 Neo, CPH1893), and Oppo K1 (PBCM10, PBCM30). Professional installation is recommended as these models have sealed glass back covers with strong adhesive. The phones are 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 10W VOOC charging performance, use the original Oppo VOOC 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.
