🔋 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 exceptional battery life of your OPPO A5X International with this BLPC21 6000mAh replacement battery. The OPPO A5X is a mid-range powerhouse designed for markets like India, Southeast Asia, and Latin America, where users demand long battery life and durability. The 6000mAh battery originally provided approximately 2 full days of moderate use and up to 12-14 hours of video playback — making it one of the longest-lasting smartphones in its class. After years of daily charging cycles, the original battery’s capacity naturally degrades. This Li-ion Polymer battery restores the full 6000mAh capacity, bringing back the multi-day endurance that sets the A5X apart from other smartphones. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Designed for Unmatched Battery Endurance and Durability: The OPPO A5X International was designed for users who prioritize battery life and reliability above all else. The 6000mAh battery originally provided approximately 2 days of moderate use, 12-14 hours of continuous video playback, and over 20 hours of talk time on 4G networks — making it a top choice for power users, travelers, and those in regions with intermittent charging access. However, after years of charging cycles, battery capacity degrades significantly. Common symptoms include: the device requiring daily charging instead of every few days, unexpected shutdowns at 15-25% battery remaining, slower charging than when new, or visible battery swelling. This replacement restores the original endurance, allowing you to continue enjoying the A5X’s legendary battery life. The BLPC21 battery uses advanced high-density cell technology with multi-layer safety protection, ensuring reliable performance for years to come.
Compatibility Note: Fits OPPO A5X International only. Please confirm your battery model before ordering — BLPC21 is printed on your original battery. This battery is NOT compatible with OPPO A5X China version (which may use a different battery variant), OPPO A5 series, OPPO A7 series, OPPO A9 series, or other OPPO models. The International version of the A5X uses a distinct 6000mAh battery with specific dimensions; using a different battery model may cause charging issues or incorrect battery reporting.
