Charging Times and Transmitter Runtimes
Use the following table to determine approximate battery runtime based on the duration of charging time when in 5.8 GHz
mode. Times shown are in hours and minutes. Transmitters automatically poweroff after approximately 1 hour to conserve bat
tery life if the signal from a linked receiver is not detected.
Receiver Bay or AC Power Source Charging Transmitter Runtime
0:15 up to 1:30
0:30 up to 3:00
1:00 up to 6:00
3:00 up to 11:30*
*Storage time or excessive heat will reduce maximum runtime.
Note: If receiver is powered off and remains plugged in, battery will continue charging.
Important Tips for Care and Storage of Shure Rechargeable Batteries
Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.
Always store batteries and transmitters at room temperature
Ideally, batteries should be charged to approximately 40% of capacity for long-term storage
During storage, check batteries every 6 months and recharge to 40% of capacity as needed
