Shure Battery Cup for PGXD2 & PGXD4 SM58 Handheld Wireless System

The Shure 65DA8451 is a battery cup that replaces the original battery compartment on PGXD2 and PGXD4 SM58 transmitters that are handheld and wireless. It secures AA batteries inside the microphone body and maintains uninterrupted electrical contact, allowing performers, presenters, and engineers to rely on consistent power throughout a show or recording session.

If the factory cup has been misplaced during a fast equipment change or damaged after extensive use, this component restores full operation in a matter of minutes. It threads directly into the transmitter housing, matching the precise alignment and fit of the original part so the batteries stay stable even when the microphone is passed around on stage or used in a busy conference room.

Keeping a spare 65DA8451 in a gig bag, flight case, or rental inventory helps live sound crews, houses of worship, schools, and production companies avoid last-minute disruptions. Because it is manufactured by Shure, you can trust its dimensions and contact points to perform exactly like the piece that shipped with the system.
