The Shure AXT920 is a premium, rechargeable lithium-ion battery pack specifically engineered for use with select Shure wireless handheld microphone transmitters, such as those in the Axient Digital and ULX-D series. Its primary function is to replace disposable alkaline batteries, providing a reliable, high-capacity, and eco-friendly power solution for professional wireless microphones. The battery is designed to integrate seamlessly with the transmitter body, maintaining the microphone's ergonomic balance and aesthetic while delivering consistent voltage output throughout its discharge cycle. This ensures optimal RF performance and audio quality without the gradual decline in power associated with disposable cells, which is critical for long events, broadcasts, or touring schedules.

Engineered for durability and long service life, the AXT920 features a robust housing and is built to withstand the rigors of daily professional use. It incorporates intelligent battery management circuitry that provides accurate runtime reporting on the transmitter's display and helps protect against overcharging, deep discharge, and short circuits. The battery can be charged using dedicated Shure charging stations like the SBC800 or SBC850, which allow for simultaneous charging of multiple batteries while displaying individual charge status. This system facilitates efficient battery rotation and management for large-scale productions, ensuring that a fresh, fully charged battery is always available.

Adopting the AXT920 rechargeable system represents a significant operational upgrade, reducing long-term costs, minimizing environmental waste from disposable batteries, and enhancing logistical efficiency. For sound engineers and production managers, it provides predictable performance and simplifies power management during critical live events, concerts, and broadcast productions. By offering dependable power with the convenience of rechargeability, the Shure AXT920 helps professional audio teams maintain uninterrupted, high-quality wireless audio transmission from the stage to the mixing console.
