Well, I know that they last at least 36 hours on the highest setting. I haven't done any tri benchmark testing, but was doing some work using it and got called away. I didn't get back to it until a day and a half later when I realized I'd left it on! It was still going at functional level at that point.

4 to 5 hours I believe... depends on what your doing with them, constant music shorter battery life...

I can't remember how the batteries are that came with them. I have some of these that are almost three years old and I don't think I've changed them more than twice. I have a few that are almost two years old now and one of them just barely started cherping a month ago. I'd say the battery lasts over a year at least. They last long enough that I haven't given it much thought.

Not long at all. I had to stop using mine. When you put batteries in you get about 8-9 good hours, then light begins to dim. It is worthless!!

I do not know exactly, but I am going to say at least two years. They rarely need changed. Battery life is impressive.

I use the Duracell AA batteries and I believe it takes 16 total. They last quite a while depending on usage.

Yes, batteries last around 6-8 months. Two AA-'s in the motion sensor and the speaker plugs into a wall outlet.

I haven't timed them. I use it for about 10 or 15 minutes per day, and I have to change the batteries on average once a month.

Not sure. I used it for a week, a few hours almost every night. I have yet to change the batteries since I got it.

They will last all night and probably 2 to 3 nights. They are powered by three 1.5 volt lithium batteries and can get pricey. However, they are nice and soothing. They contiuously change colors

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

They are 'D' batteries . They last long enough. Still like radio. Its a very simple radio.

Depends on use. We used ours for 2 nights(all night long) before we replaced batteries. We used cheap batteries

I fall asleep with them on, and the charge lasts at least eight hours with the volume on a low setting. I have never left them on longer than that, and I recharge them each morning.

I don't have exact time but I have used mine several hours now and still using original batteries.

We usually don't use ours for more than 90 minutes of continuous use. They could probably hit 2 1/2 hours with a decent battery, but it might be a stretch. I don't know if you need them to run continuously for the whole time, but we try to conserve power by turning them off when not actively in use. We're running them on Energizer rechargables.

I haven't exactly timed it and as one who has multiple batteries, I don't may that close attention and I don't run them all the way down...but I'd say about 30 mins on average.
