Shure SBC840‑US 8-bay, networked, battery-only tray charger (SB910 and SB920)

Shure SBC840-US — 8-Bay Networked Battery-Only Tray Charger (SB910 / SB920)

The Shure SBC840-US is a professional-grade 8-slot networked charging system designed for SB910 and SB920 rechargeable lithium-ion batteries. It provides a centralized, efficient, and scalable charging solution for professional wireless audio setups used in concerts, broadcast studios, theaters, and touring productions.

This charger allows users to charge up to eight batteries simultaneously while maintaining full visibility and control over battery status. It integrates into Shure’s wireless ecosystem through network connectivity, enabling remote monitoring and management via Shure Wireless Workbench software. This helps technicians track charging progress, battery health, and system readiness in real time, reducing downtime and improving operational efficiency during events.

The SBC840-US uses a battery-only tray design, meaning batteries are removed from transmitters and charged separately. This approach helps extend battery lifespan, simplifies large-scale charging workflows, and ensures batteries are consistently maintained at optimal performance levels. Each charging slot is equipped with LED indicators that provide immediate local feedback on charge status and fault conditions.

It also includes a storage mode, which safely conditions batteries for long-term storage by maintaining them at an optimal charge level. The unit is designed to fit compactly into professional racks, making it suitable for permanent installations and mobile production systems where space efficiency is important.
