It comes with four AAA batteries so you can use it right out of the box. :)

It does come with a battery. If you plan to use it for extended periods of time, you may want to buy a spare.

Im not sure where you saw that it requires a battery. Its just a case. With a magnetic to keep it closed. There's nothing electronic about the case itself.

No, it requires two AA batteries though I imagine you could use rechargeable batteries . The batteries last a pretty long time though .

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

Yep. Needs one to self charge. We've got many and it's a great value. And the batteries are easily changed out locally every few years.

Yes it does need batteries. I gave this to my grandson about a year ago and I can't remember what type of batteries it takes but he loved it.

My dad help me put it in and he said yes it does. But there should be a battery already. If not you will need one.

To be honest I really don't think one is needed. However, if you place two batteries in tandem for more speed and power then I might put one on.

Yes. It has a battery and I have used it both ways which is the reason I bought it. If I need to use it without electricity I can just as well.

NO! The use on the battery is so low its not needed. I just turn it off when I leave home for an extended period of time.

It comes with a battery, but I bought two larger (more time) batteries and haven't ever used the one that came with it.

No, it does not need batteries. It is a manual clacking spring alarm that goes off when the door is opened.

It does not need a battery in addition to the battery you're testing with. It does need a battery for testing.

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.
