🔋 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 Redmi Note 15 Pro 4G with this BN6E 6500mAh replacement battery. Released in December 2025, the Redmi Note 15 Pro 4G features a 6.77-inch 120Hz AMOLED display, a 200MP main camera, and a massive 6500mAh battery that sets it apart in the mid-range segment. After 1-2 years of daily charging cycles, the original battery’s capacity naturally degrades. This Li-ion Polymer battery restores the full 6500mAh capacity, bringing back the multi-day endurance this device was 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 Unmatched Battery Endurance: The Redmi Note 15 Pro 4G is built around one of the largest batteries in its class — the 6500mAh cell with 45W fast charging support. The 6500mAh battery originally provided approximately 2-3 days of moderate use and exceptional endurance for streaming, gaming, and daily tasks. 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 45W charging than when new, or visible battery swelling. This replacement restores the original endurance, allowing you to continue enjoying the Redmi Note 15 Pro 4G’s legendary battery life. The BN6E battery uses advanced high-density cell technology with multi-layer safety protection, ensuring reliable performance for years to come.
Compatibility Note: Fits Redmi Note 15 Pro 4G only. Please confirm your battery model before ordering — BN6E is printed on your original battery. This battery is NOT compatible with Redmi Note 15 Pro 5G, Redmi Note 15 Pro+ 5G, Redmi Note 14 Pro 4G, Redmi Note 13 series, or other Redmi models. The Redmi Note 15 Pro 4G uses a distinct 6500mAh battery with specific dimensions; using a different battery model may cause charging issues or incorrect battery reporting.
