Shure SB900B Rechargeable Lithium-Ion Battery for use with P3RA, P9RA+ and P10R+ Receivers, ULX-D, QLX-D and AD Series Transmitters and All Associated Docking, Networked and Rack Charging Accessories

The Shure SB900 battery is exactly what you want powering professional wireless systems: reliable, consistent, and built for real production environments. In daily AV and live-event use, these batteries deliver predictable runtime and accurate charge reporting, which takes the guesswork out of planning and execution. When paired with Shure receivers and charging docks, the ecosystem just works—battery health, remaining runtime, and charging status are all clearly communicated. That level of transparency is invaluable when uptime matters. Build quality is excellent, and the batteries hold up well to repeated charge cycles without noticeable degradation. Swapping out disposable batteries for the SB900 is not only more cost-effective over time, but also cleaner, faster, and far more professional on site. Bottom line: the SB900 is a dependable, purpose-built power solution that matches the quality and reliability Shure is known for. If you’re running Shure wireless and want confidence instead of compromises, this battery is a must-have.

These are kind of pricey, and I’m not sure if they ever actually pay for themselves, but they are convenient. Two good brand name AA batteries barely make it through a gig in my IEM’s. Regular rechargeable AA batteries don’t reflect accurately on the battery life monitor. These batteries will almost last the duration of two gigs even if I don’t turn off during set breaks. So I guess I am really paying for peace of mind

Works as it should but the price!!!!! They have you over a barrel so you have to buy these. They are just stupidly expensive for just a rechargeable battery. It's just a battery guys. Play fair.

This battery lasts for times longer than the 2 AA batteries. I bought 2 and the charger and have no more worries

Works great and has a pretty long life. I usually play 3 hour shows and it still has over 50%.

Perfect instead of using double A batteries

This battery does not fit in the current version of the Shure P3RA transmitter.

Brand new battery supposedly. The only guess I have is that it was sitting dead on the shelf discharged since it manufactured in April until we purchased it in October. Not good. Hopefully replacement will be better. UPDATE: Replacement was 99% health with 1 cycle which is better, so it’s hit-and-miss.
