Shure SB903 Rechargeable Li-Ion Battery Kit for SLX-D Transmitters w/ Dual-Dock Charger (2-Pack)

Shure's rechargeable power for SLX-D and SLX-D+ wireless: two SB903 lithium-ion batteries and an SBC203 dual docking charger. Each SB903 is a 3.6V, 1200mAh pack that runs an SLX-D transmitter for up to 8 hours, and once installed it shows remaining runtime in hours and minutes on both the transmitter and receiver, plus battery health and charge cycles on the transmitter. The SBC203 charges two batteries on their own or still inside their transmitters, reaching 50 percent in about 1 hour 15 minutes and full in about 2 hours 30 minutes, and it automatically mutes docked transmitters. These pair with our Shure SLXD15+ system in place of AA batteries.
