What size battery does it use?

The people who report that this uses a AAA battery must have received a different product than I did. Mine came with a 23A battery - a small battery that I have never seen anywhere else and cannot buy at my local store (must be ordered on Amazon).

23A batteries are becoming increasingly popular and can be found at many grocery stores and nearly all office or "radio shack" type stores.

No idea. I don't own one so I don't know why amazon asked me. I would check the company website, and look for the model specs. Sorry I couldn't help.

The answer is in the name of the battery. It's a 18650, which means it's 18mm x 65mm.

It doesn't come with a battery, but it does have directions. You can get the battery at almost any dept store, radio shack, etc. I think it will tell you online what size battery it uses.

Its a small watch type battery about 1/8th inch thick and about 1/8th inch smaller diameter than a dime. It takes 3 batteries each of its 2 devices. I hope this answers your question.

I use a 9v battery. You will need to adjust the battery connectors a little, as it tends to be a little wide.

Check the owner's manual for the specific battery size, and then check Amazon :)

It uses the 23AE size battery. My battery came from Ebay (5-pack); bought the remote from here on Amazon. So far the same battery has lasted more than a year.

I have been happy with it. Instead of about 2 hours of unplugged life, the battery gives 3 hours. The physical size is the same.

Believe it uses a lithium ion battery that holds a pretty long charge on it. When the battery is low plug into AC power to restore battery life.

I want to say that it uses only one AA size battery. I love this timer for my desk at work, since it is very user friendly and gives me a 10 min and a 5 minute warning beep too. Hope this helps :)

To anyone else wondering the same thing to this question. It uses 2 AAA batteries. I didn't see the details about this anywhere else on the page about this. But if you are wondering the same thing I did then this is the answer. 2 AAA batteries. I'm contacting Amazon.com regarding the person who answered me and let them know that there are trolls on http://amazon.com. Little kids should not be allowed to answer questions.

The internal battery died years ago. Have been using a mini USB phone charger since. Have also powered the device through usb hub. The device lays on my truck dashboard. Device is about 2.5" x 1.5" x .75" going from memory, as I am not at work today. Could be more precise later.

I think Mr. Perry's stats might be off a bit. I just measured the battery in my 10 year old ES 500 and it measures close to 6" x 2.6" x 3.75"

There is no regular size battery. It is a special one but I just unscrew it and Plug it in every evening and I never run out of battery. I have had it for almost a year

This model specifically uses a CR-2032 battery. If you are unfamiliar with them they are the flat round batteries about the size of a dime just a bit bigger in diameter and a bit thicker than a dime.
