I think it will work for as long as you have it on. I have not traveled over 3 and 1/2 hours with it on but I think it would keep right on working.

They usually take about 8 - 12 hours to work. On my first time taking it was very dramatic (urgent and multiple times) Now it is just regular.

I don't think it's more than a couple of hours, from a drained battery. But I'm not 100% sure. Definitely not an all day thing though.

We made an evening of it, with food and silliness. If you don't have much time, you could probably finish in a couple of hours.

I just tried mine set at 1 second - it worked fine. But, I don't know why anyone would want to set that short a play time.

I usually wait 24 hours anyways only because my schedule. I have had no adverse issues with waiting longer than the 4-6 hour recommendation.

If it's a big job, the charge will last about 20 minutes; on a smaller job, you'll get a bit over a hour. (Sorry for the delay with my response; I've been offline for a bit, but wanted to give you an answer since I had been asked. :)

Should work for days if necessary. Have only needed it for a couple of hours so far.

It didn't take that long to charge my new battery. I would think a few hours would be good. Maybe you got a new battery that was bad?? Hope this helps...

We go through hours pretty fast. So I don't think I can answer your question.generally though, I do have a concern about overall quality.

You have to add the hours manually, but it is not difficult to do. If you had a large number of workers it might be cumbersome, but we only use it with one employee so it is not a problem.

If you live a a warm climate it could take less time. 48 hours is just a rule of thumb.Don

Depending on what you are doing, the battery should last more than 2 hours of use.

I could not verify that, our use has always been limited to a few hours of need, and not for a machine as presented. It has worked for our specific needs very well.
