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

C-batteries. But, we have a converter that changes it to rechargeable 2 AA's & it seems to work fine.

They are your standard rechargable AA batteries. You can find them at any home improvement center or hardware store.

I'm not sure, but the type of battery is easily available and will need to be replaced someday anyway. Good product.

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

C batteries. Don't buy this thing... two of them have died on me! It's not well made.

2 - 3Volt 123A Batteries. You can use any type but I prefer the Surefire Brand myself.

They are small hearing aid type batteries. They come with the unit, and I have not had to replace them in the 2 yrs I have used the item.

standard AAA batteries. They last a very long time. They are very easy to change.

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.

it uses AAAA batteries. A little harder to find than some, but not that bad.

I purchased one last Christmas. I don't remember what kind of batteries it needed. It did work great.

Regular AAA batteries do the trick fine. Very compact and bright. Recommended.

They take rechargeable AA. Not that it matters. I replaced them thinking cheap factory batteries might be the issue. Nope. The units in my opinion are just junk, plain and simple.
