Is it powered by a battery? And if so, what is the battery life?

The general time is about 7 years and the batteries are not replaceable. Considering tires do not last 7 years for the average driver, and even less keep cars that long. It seems to be a non-issue at this point with most drivers.

No, it's battery powered...3 double A's. Mine is still using the same batteries I put in it originally, well over a year ago.

It has a built in rechargeable battery. You can the battery or electricity.

It is battery powered only. It seems to use little battery power, I'm still using the original batteries I installed.

It's battery operated. Don't waste your money though, it's pretty much useless.

I'm not sure. I keep it plugged in. Sorry I can't be much help regarding the battery life.

No, it's not battery powered. It runs on 110V only. There is a battery in the hand piece to activate the sonic vibration function.I would not travel with this thing, it's way too big.

no battery, not rechargeable. it plugs in the outlet, or it can be plugged in the car.. I use it only at home, not in the car.

It is not battery powered. It plugs in the wall socket. One comment the light is not that bright. No sure if you can get a bright bulb for it.

Yes. Plugs in or runs on battery. I've found the battery to last about 8 hours

Strictly battery powered. Uses 3 AAA batteries wired in series. It also comes with 3 batteries that I have yet to replace.

It's battery operated. But don't worry, it doesn't work with batteries, either.

It doesn't use batteries. It gets its power from the USB connection on the laptop or computer.

Yes it is battery operated but the batteries seem to last quite a while. I'm pretty sure that you can plug it in too, if you have the right cord (not included) but that would not be that convenient if using outside.
