What battery type does this use?

It uses a calculator battery - LR 44. My son is an engineer, his is a different brand and takes a AAA. I do not know how accurate it is, but being a Mechanical Eng, I think he'd be looking for something that can do 0.001 like this one.

It uses a small, onboard battery for its power source. I believe it's a AAA battery - should say in the description.

Most likely a small flat round battery. They come with batteries and they last long.

It uses a lithium coin battery CR2032. It's easy to put a new battery in the device. As the previous answer indicated, the batteries can be expensive, if purchased in a retail store. I have also purchased replacement batteries on Amazon as there are no retail pharmacies, or electronics store which carry that battery.

I am sorry I don't know what kind of batteries you are describing. What are they used for?

It uses the 18650 batteries. They are sold on Amazon. Be sure to get the RECHARGABLE ones. They are much larger than the AA batteries.

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.

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 apologize, it does use a battery. You plug in the receiver into the wall. I don't remember the battery type. Sorry. :)

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.

I only use regular batteries, I honestly do not know about that, sorry. I guess we'll have to do some research.

It uses a 3v lithium battery (round disc) it comes with a working battery so you shouldn't hav to change it for awhile. The cost is around $2 or $3 for the battery

Not sure of the type of battery but it lasts very long as long as you turn it off after use and comes with an extra. If you are considering buying it then just do it, it is a great scope.

The battery type is not indicated on the device itself. However, I own other batter packs from them and those are Lithium Ion. So I am going to assume this are Li-ion.

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

I finally found the battery in the box it came in. It is a 3V lithium battery, type CR2025.

It's a CR2016 3V button battery. You can get it online, at Radioshack or even Walmart I believe
