✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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 battery life of your Xiaomi smartphone with this BN5D 5000mAh replacement battery. Compatible with Xiaomi Poco M4 Pro 4G (released February 2022, featuring a 6.43-inch 90Hz AMOLED display and MediaTek Helio G96 processor), Redmi Note 11S (February 2022), and Redmi Note 11 4G (November 2021). All three devices feature a 5000mAh battery with 33W fast charging support. This Li-Polymer battery delivers the factory-rated 5000mAh capacity for all-day usage — keeping you powered through streaming, gaming, and daily tasks without constantly reaching for a charger. For reference, third-party retailers sell this battery for approximately $13 to $25.
Built with high-quality Grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, short circuit, and overcurrent. CE, RoHS, and UN38.3 certified for safe transport and use. The 33W fast charging capability allows the compatible phones to charge quickly when paired with the original Xiaomi adapter. Built-in protection chip helps extend battery lifespan. For reference, third-party retailers sell this battery for approximately $13 to $25.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BN5D. This battery is compatible with Xiaomi Poco M4 Pro 4G (2201117PG), Redmi Note 11S (2201117SG/SI), and Redmi Note 11 4G (2201117TG/TI). Professional installation is recommended as these models have sealed back covers with strong adhesive.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best 33W fast charging performance, use the original Xiaomi charger and cable that came with your phone. If you don’t use the battery for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

Frequently Asked Questions

The BN5D battery for Xiaomi Poco M4 Pro 4G is compatible with Xiaomi Poco M4 Pro 4G (model 2201117PG), Redmi Note 11S 4G (models 2201117SG, 2201117SI), and Redmi Note 11 4G (models 2201117TG, 2201117TI). The Poco M4 Pro 4G was released in February 2022 featuring a 6.43-inch 90Hz AMOLED display and MediaTek Helio G96 processor. The Redmi Note 11S features a 108MP main camera, while the Redmi Note 11 4G features a 50MP main camera. If your Xiaomi battery replacement is needed because the phone drains quickly or won't hold a charge, this is the correct battery. Please verify your device model in Settings > About Phone and check the battery model BN5D printed on your existing battery before purchasing.

The BN5D 5000mAh 3.87V battery has a typical capacity of 5000mAh (19.3Wh) and a rated voltage of 3.87V. Charge limit voltage is 4.45V. It is a Li-Polymer battery built with Grade A cells and is CE, RoHS, and UN38.3 certified. The Xiaomi 5000mAh Li-Polymer battery supports 33W fast charging — all compatible devices (Poco M4 Pro 4G, Redmi Note 11S, and Redmi Note 11) feature the same 33W Pro fast charging capability. For best results, use the original Xiaomi charger and cable that came with your phone.

Professional installation is strongly recommended for Xiaomi phone battery installation. The Poco M4 Pro 4G, Redmi Note 11S, and Redmi Note 11 all have sealed designs with plastic or glass back covers secured by strong adhesive. The process to replace battery in Redmi Note 11S requires heating to soften adhesive and careful prying to avoid damaging the display or back cover. Water resistance is not a concern as these models have no official IP water resistance rating. If you choose DIY phone battery replacement, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor.
