Portable microphones should use consumer-grade nickel-metal hydride batteries, designed specifically for everyday performances, indoor live streaming, and other similar scenarios. The battery should support 8-12 hours of continuous audio output and Bluetooth connectivity, be compatible with a drop- and splash-proof design, and feature a memory-free charging capability for convenient use. Its environmentally friendly, recyclable materials and over 1000 cycle lifespan balance affordability and low maintenance costs, making it suitable for frequent charging and discharging needs.
