🔋 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 Redmi 5 Plus with this BN44 4000mAh replacement battery. Released in December 2017, the Redmi 5 Plus was one of Xiaomi’s first 18:9 aspect ratio smartphones, featuring a 5.99-inch Full HD+ display, Snapdragon 625 processor, and a 12MP camera. The 4000mAh battery combined with MIUI’s battery optimization provided excellent endurance. After 7+ years of use, the original battery capacity has likely degraded significantly. This Li-ion Polymer battery restores the full 4000mAh capacity, bringing back the reliable all-day performance the Redmi 5 Plus was 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 Redmi 5 Plus Users: The Redmi 5 Plus was designed for users who valued long battery life and a large display. The 4000mAh battery originally provided approximately a full day of heavy use and up to two days of moderate use. 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 BN44 battery supports standard 5V/2A charging — full charge takes approximately 2-2.5 hours. MIUI is optimized for battery efficiency, and a fresh battery brings back the smooth, responsive experience the Redmi 5 Plus was known for.
Compatibility Note: Fits Xiaomi Redmi 5 Plus (MEG7) only. Please confirm your battery model before ordering — BN44 is printed on your original battery. This battery is NOT compatible with Redmi 5, Redmi Note 5, Redmi Note 5 Pro, Redmi 6 series, or other Xiaomi models. The Redmi 5 Plus uses a distinct 4000mAh battery with a specific connector orientation.
