A single AA, and NiMH works just fine. I get a week or two out of mine, using the mouse all day long.

No idea. They were just your standard-sized AAA batteries when I bought them.

They are button batteries and seem to be quite reasonable, ranging from about $2.50 to $8 a 10-pk. Check Amazon. Hope this helps.

I use whatever batteries I have lying around. The overheating ones were generics.

Batteries, AAA if I remember correctly (I don't have it with me at the moment)

I don't know the exact battery type, because it is a sealed unit, (probably nickel-metal hydride (Ni mH)). It does not come with a "spare" battery, just the one in the unit when you buy it, and this battery does ot appear to be user-replaceable. It charges through the supplied cable to a USB port, or if you have one of those adapters that charges USB devices directly from an AC outlet.

(2) AA Batteries. Alkaline or Lithium both work. Make sure your settings reflect which one you use.

The recommended batteries to use are two(2) Eveready CR-2016. They are a 3V lithium coin cell.

Any AA batteries will work, I used regular ones and they are still working two months later

Hey, I'm not sure the exact type it said as I gave it as a gift. But from what I saw when I was installing them for the person I gave it too, they are watch-type batteries, just a little fatter, if that makes sense. Sorry I couldn't be more helpful. And I am truly sorry for my late reply, I've been out of town with family. Happy Holiday's! Edit: But they do have a set that come with the Screwdriver initially, so it will be able to answer the question better once you get the item :3

I'm sorry I do not understand your question. Are you asking what brand they are? They are great batteries and last a while. I would recommend them to anyone for the price and quality.

Do you mean what type of battery, if so it takes three Double A batteries. If this is not what you want to know, please add a little more info to your question.

These are foreign batteries, but you can buy them on amazon. I have also seen them on ebay, but amazon has always been cheaper. Do not try other batteries because of the voltage used. US batteries are not the same!

Any brand as long as they are NiMh batteries. Just be sure that they are not old NiCads.

I went to Batteries + and they gave me (2) two CR123A batteries that work great. Bought a 6 pack.

Regular batteries, but don't waste the batteries. Not a good product. Poor performance

They use a common battery, (I believe it was a AAA). They are in my travel bag ready for my next trip.
