🔋 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.

Revive your Xiaomi CC9 or CC9e with this BM4F 4030mAh replacement battery. Released in July 2019, the Xiaomi CC9 series was designed for users who prioritize photography and selfie quality — featuring a 48MP Sony IMX586 rear camera and a 32MP front camera on the CC9, with a 13MP rear camera on the CC9e. Both models share the identical BM4F 4030mAh battery, making this replacement compatible across the series. After 5+ years of use, the original battery capacity has likely degraded significantly. This Li-ion Polymer battery restores the full 4030mAh capacity, bringing back the reliable all-day performance these devices were known for. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why This Battery Replacement Matters for Xiaomi CC9 Users: The Xiaomi CC9 series was designed for users who value camera quality and battery life. The 4030mAh battery originally provided approximately a full day of heavy use, with 18W fast charging delivering a full charge in about 90 minutes. However, after years of charging cycles, the original battery’s capacity drops significantly. Common symptoms include: the phone needing multiple charges per day, shutting down at 15-25% battery remaining, slower charging than originally, or the battery swelling. This replacement restores the original battery life, saving you from buying a new phone. The BM4F battery is fully compatible with the phone’s 18W fast charging. MIUI is optimized for battery efficiency, and a fresh battery brings back the smooth, responsive experience the CC9 series was known for.
Compatibility Note: Fits Xiaomi CC9 (M1904F3BC, M1904F3BG) and Xiaomi CC9e (M1904F3BT, M1904F3BU). Please confirm your battery model before ordering — BM4F is printed on your original battery. This battery is NOT compatible with Xiaomi Mi 9 series, Xiaomi Mi 9 SE, Xiaomi Mi 9T, Redmi K20 series, or other Xiaomi models. Always check your original battery before purchasing.

Professional Xiaomi CC9 battery installation is recommended. Both the Xiaomi CC9 and CC9e have sealed glass backs with strong adhesive. To replace Xiaomi CC9 battery M1904F3BC, the technician must heat the back cover to soften adhesive, carefully pry it open to avoid cracking the glass, disconnect the battery's small 2-pin connector, remove the old battery (lightly adhered), and install the new BM4F battery before resealing. The AMOLED display is fragile, and improper prying can damage it. Third-party repair shops typically charge $20-35 for labor. Xiaomi official battery replacement costs vary by region. For Xiaomi CC9 battery health maintenance: 1) Use only the original Xiaomi 18W charger and cable for optimal charging. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the phone to high temperatures (above 40°C / 104°F), especially while charging. 4) For long-term storage (over 2 months), keep the battery at approximately 40-60% charge. 5) Perform a full calibration cycle after installation: drain the phone until it auto-shuts off, then charge uninterrupted to 100% using the original 18W charger. For Xiaomi CC9 battery care tips, stop using immediately if the battery shows any swelling.
