🔋 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 Redmi K50 Pro with this BM5E 5000mAh replacement battery. Released in March 2022, the Redmi K50 Pro features a 6.67-inch Samsung 2K E4 AMOLED 120Hz display, MediaTek Dimensity 9000 flagship processor, 108MP OIS main camera, and supports 120W HyperCharge fast charging technology with Xiaomi‘s Surge P1 charging management chip. This Li-Polymer battery delivers the factory-rated 5000mAh capacity for all-day usage — one of the largest batteries in its class at launch, offering extended power for gaming, streaming, and daily tasks. For reference, third-party retailers sell this battery for approximately $25 to $40.
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 BM5E battery supports 120W HyperCharge — when paired with the original 120W charger, the phone can charge from 0% to 51% in just 10 minutes and from 0% to 100% in approximately 19 minutes, making it one of the fastest-charging smartphones ever released. The battery features high-nickel cobalt manganese ternary positive electrode material and silicon-carbon composite anode system, achieving approximately 12% higher energy density with 5.3% volume reduction compared to previous generation. The battery has passed over 2000 charge-discharge cycle tests in Xiaomi‘s in-house lab, maintaining no less than 80% capacity after 800 cycles.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BM5E. This battery is compatible with Redmi K50 Pro (models 22021211RC, 22011211C) — the 120W HyperCharge flagship model. This battery is NOT compatible with Redmi K50 (which uses BM5F, 5500mAh) or Redmi K50 Ultra. Professional installation is recommended as the phone has a sealed glass back cover with strong adhesive. The phone is rated IP53 for splash resistance, so proper resealing after replacement is recommended to maintain protection.
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 120W HyperCharge performance, use the original 120W charger and 6A-rated 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 BM5E battery for Redmi K50 Pro is compatible with Redmi K50 Pro (models 22021211RC and 22011211C) — the 120W HyperCharge flagship version. The Redmi K50 Pro was released in March 2022 featuring a 6.67-inch Samsung 2K E4 AMOLED 120Hz display and MediaTek Dimensity 9000 processor. This 5000mAh battery for Redmi K50 Pro 22011211C is a direct replacement for the original BM5E battery. Important: This battery is NOT compatible with Redmi K50 (which uses BM5F, 5500mAh) or Redmi K50 Ultra. If your Redmi K50 Pro 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 BM5E printed on your existing battery before purchasing.

The BM5E 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 Redmi K50 Pro supports 120W HyperCharge — when paired with the original 120W charger and 6A-rated cable, the phone can charge from 0% to 51% in just 10 minutes and from 0% to 100% in approximately 19 minutes according to official specifications. The battery features Xiaomi’s Surge P1 charging management chip with dual-core series charging architecture, achieving an energy conversion efficiency of up to 98.6% and effectively reducing heat generation. The battery has passed over 2000 cycle tests in Xiaomi‘s in-house lab, maintaining no less than 80% capacity after 800 cycles. For best results, always use the original 120W charger that came with your phone — using other chargers will not achieve the same fast charging speed.

Professional installation is strongly recommended for Redmi K50 Pro battery installation. The Redmi K50 Pro has a sealed design with a glass back cover (nano-microcrystalline glass technology) secured by strong adhesive. The process to replace BM5E battery in Redmi K50 Pro requires heating to soften adhesive, careful prying to avoid damaging the display or back cover — the phone features a large 2K AMOLED display that is particularly delicate during disassembly. The phone is rated IP53 for splash resistance (protects against splashing water at an angle up to 60 degrees), so proper resealing with fresh adhesive is necessary to maintain this protection after replacement. 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), use plastic tools to avoid damaging internal components, and note that the BM5E battery uses dual ribbon cables — disconnect in the correct order to avoid damage. Third-party repair shops typically charge $20-40 for labor.
