Yes they have an on/off switch. I can't attest to battery life except to say they sounded loud when I tested them prior to installation and again when the standard time went into effect (like with smoke alarms). Very easy installation just make sure unit is swiched off and open with screws to reveal batteries and remove protective plastic and replace cover. Hope you never have the opportunity to hear them working!

Yes they can be turn on and off but I can not tell how long the batteries last

Yes, it has an off/on button. I turn it off when I open my windows during the summer. I have had this for several months and the battery is still working. I am very happy with it.

Make sure you check the on/off button to turn them on. Ours worked fine. I had to figure out there is an on/off. It was not that obvious.

No, they do not turn on. That would cause an unnecessary draw on the battery and take away from the motor. Also having constant running lights would diminish the batteries life.

There isn't any on/off button but you don't need one. It seems to stay charged a long time (weeks).

Yes. There is a on & off button. Therefore, you can keep this feature on/off.

One of the on buttons turns them on and they stay on. The other on button turns them on - and then turns them off 4-6 hours later. It would help if the words on the bottom (on, off, on) were in a different color so you could read them easier!

Yes, these do turn on when dark approaches. And turn off after about 6 hrs. They are so comforting.

They have a switch on the bottom that you can set to on, off, or auto. Set it to auto and it will stay on for 5 hours. I have some that I turned on at 5pm so they stay on till 10, some that I turned on at 6 that stay on till 11pm. Easy! We've had them since xmas and still LOVE them! :)

yes, they stay on once they are turned on until you physically hit the off button. It's much easier to just leave them on rather than go through the pairing of the speakers to the bluetooth adapter every time they speakers are powered up....just my opinion.

They do not auto-off. The manual says they do, but it's a lie. I own two of them.

No, no turn on or off - you just plug them in and they heat up, unplug to shut off.

Approximately 8 and sometimes 10 hours if I leave them on and if I buy really good batteries. They are easy to turn off and on to save battery life and easy to change the batteries

Yes they are battery operated, but you can not change the battery, they are sealed into the unit.

I leave it on all the time. I don't remember it having a on/off switch. Also the battery lasts months on a full charge.

Unfortunately, it does not have an on/off button. But because of the clock feature you really wouldn't want it to. Plus it has good battery life so there really are no disadvantages due to its lack of an on/off switch. Hope this helps!

They are on timers. They go off 4 hours after you turn them on, they are amazing!!!!

They stay on if they are playing something (if sound is coming out). Once the input stops, they turn themselves off quickly. I don't know the exact length of time, but I'm guessing 5-10 minutes. I agree that it is annoying, because I use them across the room to boost my TV sound and so I have to get up and turn them back on a lot. If you were using them at a desk, it probably wouldn't matter as much.
