Hello Don, the button battery has given me as much as 4 continuous hours without beginning to fail. I did a stress test on a couple from a bulk package when I first purchased the unit. One I simply left on and checked six hours later and it still had a weak signal. The other I left the unit on for eight hours and there was no power at all. So it would appear 4 hours is optimum.
I suppose, if I had the knowledge, rigging with a longer-lasting power supply might be an approach, especially for events in excess of 2-3 continuous hours of audio need. But this fits the bill for most of my audio session requirements.
