Does this absolutely require a battery for use?

With no battery or a dead battery, the scope's cross hairs are black. If the battery is good, you can choose either red or green, depending on a knob setting on the side of the scope. Each red and green have 3 levels of brightness, also selected with that same knob.

Requires flat coin sized battery that lasts a long time to light the reticle. Otherwise, just looking through glass

No, you have black crosshair without batteries or it turned on. It is a lot easier with them though.

Yes it does come with a battery. My usage hasn't been heavy so it more than serves my purposes but if you consider yourself a heavy user then by all means get a spare, it may come in quite handy.

Yes, you have to plug into electrical outlet to have it work, there is no internal battery.

It does not. It's far and away better than a popular model that does use batteries.

Yes. I have not needed. A long acting battery has lasted more than 4 months so far

It definitely is powered by a battery but I do not recall if it came with one. I seem to think it requires a 9v. Sorry that I could not be sure.

No, this is a dynamic (condenser) mic, it does not require batteries; it needs to be connected with a cable (XLR). This mic is usually used for instruments.

No! It uses batteries. And a lot of them too. The batteries go dead very quick!

No. It does not require batteries. It uses the 24 volt power from the HVAC unit.

Yes, but I use the battery alone without the plug in power. My shop is off grid so it is nice that I don't need to plug it in.

no. But I have mine plugged in beside my chair. Just turn it on when needed. I have never put batteries in. If you travel you might want the battery option.

No, it does not use batteries which makes it perfect. It's plug in... Love this machine....

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 :)

No. No battery required. Blow into the tube and while hitting the keys. It is a wind instrument of sorts.

No. It has a built in battery that is charged via a USB cable that is included.

Yes, it needs to be plugged in. I am sure there are some battery operated models, this one, however, is not one of those.

Yes, it requires batteries, but don't buy this product. I did, but the build quality is horrible. It broke after six months. I saved up some money and brought a Fluke instead, which has been rock solid.
