Shure SB903 Lithium-Ion Battery 3.6 V 1,200 mAh

Keep SLXD1 transmitters on air longer with the Shure SB903 lithium-ion battery. Built around a 3.6 V, 1,200 mAh cell, it delivers up to 8 hours of battery life for production environments where uninterrupted wireless performance matters. That runtime gives audio teams more margin across rehearsals, corporate events, houses of worship, and live shows, reducing the need for mid-session battery swaps. This battery is designed for Shure wireless workflows, where consistency and predictable power matter as much as sound quality. Its rechargeable design supports repeated use, helping lower consumable costs over time compared with disposable alternatives. For teams managing multiple transmitters, the SB903 simplifies inventory and keeps spare power ready for fast changeouts. When uptime is part of the job, power accessories need to be as dependable as the system they support. The SB903 gives SLXD1 users a purpose-built battery option sized for professional audio demands, with the runtime and form factor expected in a premium wireless kit.
