The Shure SB903 is a rechargeable lithium-ion battery that powers any SLX-D transmitter for up to 8 hours. When using the SB903, the transmittter's LCD shows the remaining battery time in minutes and seconds.
The battery can be recharged using an SBC10-903 single-battery charger or an SBC203 dual-docking recharging station (both available separately). The SBC203 offers comprehensive power management, letting you charge two batteries without removing them from the transmitters.
