The Shure SBM920 is a dedicated battery charging module designed as a core component for the Shure SBR series of rack-mounted battery chargers, specifically for managing Shure SB900 series lithium-ion batteries used in Axient Digital wireless systems. This intelligent module embodies the advanced charging technology required to safely and efficiently service professional rechargeable batteries. It implements a precise, optimized charging algorithm that continuously monitors individual cell voltage and temperature, ensuring each battery is charged to its full capacity while maximizing its cycle life and maintaining long-term reliability. The module is responsible for the critical communication between the charger's management system and the battery's internal circuitry.

Designed for integration into multi-bay charging chassis, the SBM920 module provides the essential per-bay functionality that enables features like individual charge status reporting, health diagnostics, and remote management via network connectivity. It represents the fundamental building block of Shure's sophisticated battery management ecosystem, transforming raw electrical power into a controlled, data-informed charging process. For technical staff and service centers, the SBM920 is a key serviceable part, allowing for the maintenance and repair of the charging infrastructure that supports large fleets of wireless equipment. Its focus on precision and safety ensures that valuable batteries—and by extension, the wireless systems they power—are maintained in peak operational condition.

In professional audio environments where system uptime is critical, the reliability of the charging system is paramount. The SBM920 module plays a vital role in this infrastructure, ensuring that every battery inserted into the charger is handled with the care necessary to support uninterrupted performance during broadcasts, theatrical productions, and major live events.
