Voice Recording: Maximum Length / Will Auto-Power-Off stop recording?

No time limit, worked well for a meeting for me. In fact I was able to understand a speaker who was talking so softly I had trouble hearing live. I also have an Olympus dedicated digital recorder. This is more convenient, is voice actuated and easier to turn on and off etc., but had I had the clip at the time I certainly wouldn’t have bothered to purchase the Olympus. Strangely, the Olympus is rated for some un-godly number of hours of recording at it’s lowest fidelity setting, but the 2 AA’s would need to be replaced a couple of times during the session!
