• 📌 Serial number: At the bottom of the box is marked unique S/N (The serial number, which must match the number on the battery itself.
• 🖼️ Barcode and QR: The code must be scanned and led to the official Xiaomi website (more on this in the next section). QR Often leads to third-party resources or is not scanned at all.
• 📏 Size and weight: The original box weighs ~50-70 d (depending on the battery model) Counterfeiting is often easier on the battery 10-20 d due to the thinner cardboard.

2. The original QR should redirect you to the view page: https://order.mi.com/site/product/verify?code={UNIQUE CODE} where instead of {UNIQUE CODE} there will be a combination of 16-20 characters.
3. On the page that opens, you will see: Battery model (for example, BM4B for Redmi Note 10 Pro), Serial number (S/N). Production date. Status "Authentic Xiaomi Product" (in English - "Genuine Xiaomi Product").
