It takes either a double A battery (1.5 volts) or a 14500 battery (3.6 volts). Two different batteries that are the same size. Either way, it only takes one battery.

It does not come with batteries. It requires three. Any AA batteries will work, rechargeable or otherwise.

Got if for great granddaughter. Have no idea about batteries for it. But reading the responses I see someone said it took 3 AA.

It takes the little flat CR batteries that look like a quarter. I don't remember the detail number but it is in the instructions and unit. They seem to last forever.

Does not take batteries, I believe it comes with an adaptor for the car. So small you can put in your purse and take anywhere.

No batteries needed. Just need to plug it in and charge it for a couple hours before use.

It takes AA batteries. I didn't mind it so much at all, we just bought a big package of them and kept 4 handy while we were out.

It takes 3 little button cell batteries, LR1130. It came with the batteries in it, and so far they're going strong.

If you mean what kind of batteries you need to install in it, it takes three (3) AA batteries and they are to be installed in the back of the unit. Hope this helps.

I bought it for a gift, but I'm pretty sure it uses regular AA or AAA alkaline batteries. They come included...

Just batteries, but I bought mine a while ago. They may have changed it. It is really great on battery life though! We still use it and have never had any problems.

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.
