Restore the long-lasting battery performance of your OPPO device with this BLP727 5000mAh replacement battery. The OPPO A5 2020, A9 2020, A11, and A11X are known for their massive 5000mAh batteries, delivering exceptional endurance that set them apart in the mid-range segment. The A5 2020 features a 6.5-inch display and a quad-camera setup, while the A9 2020 offers a 6.5-inch display with a 48MP main camera. The A11 and A11X continue this legacy with similar battery-focused designs. After 1‑2 years of daily charging cycles, the factory battery capacity naturally degrades. This Li‑ion Polymer battery restores the full 5000mAh capacity, bringing back the reliable all‑day endurance these devices were designed for. 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 Long‑Lasting Endurance: The OPPO A5 2020, A9 2020, A11, and A11X are built around a 5000mAh battery that originally provided up to two days of moderate use. OPPO engineered these devices with advanced battery optimization to maximize runtime. After years of use, the original battery capacity degrades significantly. Common symptoms include: the device requiring daily charging instead of lasting multiple days, unexpected shutdowns at 15‑25% battery remaining, slower charging than when new, or visible battery swelling. This replacement restores the factory‑spec 5000mAh capacity and supports the original fast charging capabilities. The battery uses high‑density cell technology with precise voltage control, ensuring stable output and compatibility with the device’s original charging circuitry.
Compatibility Note: Fits OPPO A5 2020, OPPO A9 2020, OPPO A11, and OPPO A11X only. Please confirm your battery model before ordering — BLP727 is printed on your original battery. This battery is NOT compatible with OPPO A5 (non‑2020), OPPO A9 (non‑2020), OPPO A7 series, OPPO A3 series, OPPO Find series, OPPO Reno series, or other OPPO models. The BLP727 battery has specific dimensions and connector layout; using a different battery model may cause charging issues or incorrect battery reporting.
