Bob, Typically if the microphone is an electrette condenser it will last around 6 months. If your microphone is the one with the amplified out put that you can plug into the high level input on the ptr1 then the batteries will not last this long -- although since mine have not yet died I can't tell you exactly how much shorter it will be. There is no way to moniter the battery's level while they are in the microphone. You can remove it and use any one of the inexpensive audible battery testers that are available or pay $200 for an omega talking volt meter.

The mike requires one triple A battery. Does anyone know how many hours the battery will last. How can i tell if the battery gets low in the mike?
