Shure SB904 Rechargeable Battery for GLX-D+ Wireless Transmitters

The Shure SB904 is a battery that uses lithium ion chemistry and is purpose built for GLX-D+ wireless transmitters. It supplies up to 12 hours of continuous operation on a full charge, so performers, presenters, and engineers can focus on the mix instead of thinking about power.

Inside the 2420mAh pack, smart circuitry measures every milliamp and shows remaining runtime in clear hours and minutes. A quick glance lets you decide whether to finish another song, begin the next service, or swap before a critical take.

Charging is flexible. Slide the battery into the docking bay of a GLXD4+ or GLXD4R+ receiver, drop it into the optional SBC904 sled charger, or plug a USB C cable straight into the handheld microphone or bodypack. No external trays or disposable cells are required.

When time is short, a 15 minute quick charge delivers about 1.5 hours of use, which is plenty for a soundcheck, a rehearsal, or a short corporate presentation.

The advanced chemistry resists memory effects, so you can top the battery up whenever convenient without going through full discharge cycles.

From houses of worship and conference centers to small clubs and touring rigs, the SB904 keeps GLXD1+ bodypacks and GLXD2+ handhelds powered all day while reducing the cost and waste of disposable batteries.
