Does this item need a battery to operate?

No it does not require an extra battery. The meter works off of the battery you are testing.

No, it is a simple volt meter that uses the battery you are testing to supply the needed power. It has two scales printed on the face of the meter, one for button cells and one for all others.

This device does not have a battery, it operates on the batterys power, the meter does not light up so it is a unit that is self contained and uses the battery power that you are testing, hope it helps. doobiedoo

No it does not as far as I can tell. At lease we didn't put one in and I don't immediately see a place to put a battery.

There are no batteries necessary. The unit is powered by a transformer that plugs into a standard wall socket.

No. It requires 1- AAA battery and needs headphones or speakers plugged into the 3.5mm jack in order to operate.

no batteries. I leave mine plugged in and turn the power button off when not in use.

No, I doesn't have a battery. It is quite movable if everything is wireless and you have AC power available.

No, it runs on batteries. Just a heads up on this item, the screen is not too clear and is not in color.

I does need a power source in order to operate. Find an object to hind the power cable i.e. plant, bookshelf, vinyl tube...There is no battery in the camera.

It doesn't require batteries. It must be plugged into an electrical outlet.

If I remember it does not require batteries. To make sure, either call Amazon or inquire through their Customer Service. I gave this to my grandson last year and I am pretty sure it did not require batteries.

It does not have a battery. I'm not a computer genius, so I can't tell you how it manages to work without a battery, but I know that it does. No need to worry about replacements :)

The product I have does not require any batteries, maybe if there is one to purchase with a 'light' added it may need batteries, however the stand alone needs none!

No, it is battery operated. They did have a more expensive model that had a 10 year battery but it was to expensive for my budget.

There is no battery. It uses an A/C adapter with a USB connection so it's electrical. I believe the answer to your question is Yes. I use it all the time walking all over the place. I've walked within 500 feet of the receiver before having the sound impaired. This of course will depend on the clear signal to the receiver.
