Show Works Tip:
Rechargeable batteries have a different ‘voltage’ curve when they a providing power/being drained.
For the first 30 minutes after putting freshly recharged batteries in your wireless microphone, the microphone will stay on 3 bars and then after such time will drop down to 2 where it will stay on 2 bars for at least 3-4 hours. After this extended period of time, the microphone will eventually drop down to 1 bar indicating around 30 minutes of running time left. This is when you need to change the battery(s).
Many wireless microphones don’t have ‘battery profiles’ for rechargeable batteries so it is important to note how they behave, so you know how long you have left and when to change them.
