What kind of batteries does it take?

It is my understanding that the wristband is a sealed unit and the batteries are not replaceable. The receiving/alarm unit is direct current and plugs into an standard electrical outlet.

4 - AA batteries are required, although I just use it plugged in. Works great!

I have no idea since it was a gift for someone. You can probably take it to Radio Shack and they can tell you what type of battery it needs. Hope that helps.

It does not take batteries. I have a power converter in my car, and I have plugged it into that to use while traveling, but it really is not meant to be terribly portable.

It takes two CR123 or DL123AB batteries. Use lithium batteries for longer life.

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

Hi, it uses regular AA alkaline batteries, but I don't believe it came with any.

Sorry, it does not take batteries of any kind, it requires a plug to work, but I love it still.

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 LR1130 button batteries. I bought some from Amazon on a card that had 10 batteries, Maxell brand, for maybe $10 bucks.

It takes AA batteries, which are included. We haven't had to replace them yet.

Amy,They don't take batteries. They require a standard household power connection, normally 115v in the US.

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

It doesn't take batteries. You plug it in - either in the USB port in a computer or else in the regular outlet in the wall - you can do either one.

It takes 4 AA batteries. The batteries I have used have lasted a long time. I haven't used rechargeable batteries in it yet.

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.
