Shure Rechargeable Lithium-Ion Battery SB900B

The Shure SB900B is a rechargeable lithium-ion battery designed to keep Shure wireless and personal monitoring systems running smoothly through rehearsals, broadcasts, and live shows. It slides straight into Axient Digital, ULX-D, QLX-D, and SLX-D bodypack transmitters and receivers, and it works just as effortlessly with PSM 900, PSM 1000, and PSM 300 (P3RA) in-ear monitor packs. By switching to this rechargeable power source you avoid the recurring cost and waste of disposable batteries while gaining a stable power reserve that performers and engineers can trust.

Engineered for professional environments, the SB900B delivers consistent runtime that helps stage crews schedule changeovers with confidence. Touring fronts of house, fixed installations, and houses of worship all benefit from the ability to recharge performance after performance without compromising audio quality.

An intelligent thermal protection circuit adds another layer of security. If internal temperature ever reaches 140 °F (60 °C) the battery automatically shuts down, safeguarding both the cell and the connected transmitter or receiver. Once conditions return to a safe range, normal operation resumes and overall battery life is preserved.

Whether you manage a rack full of wireless channels or carry a single bodypack for daily work, the Shure SB900B offers a practical, dependable power solution that keeps the focus on the show, not on battery levels.
