It depends- you can use ONE- CR2032 battery or TWO- CR2016 batteries. It works either way.

Single battery. When and if u fly make sure the extra batteries are in ur carry on. If in checked baggage they will confiscated the batteries as dangerous cargo.

You can do either of the two. You can charge one single battery, or charge two batteries simultaneously. It does not matter at all.

What is stupid is all the arguing here. Having two batteries is a great idea compared to having only one. M. Kinnamon, if you need more than the 50 minutes charge time for cleaning that these two batteries give you, then buy an extra battery, or a corded vacuum. Pretty simple.

One battery. but it does take a very good picture, and the battery last a long time.

One AAA Battery. I prefer to get the lithium batters since they last longer.

It's only one. A 12 volt rectangular battery like a miniature car battery, They're not your usual double aa's or anything like that if that's what your thinking.

It depends on usage. I use mine on a Black and Decker Small hand drill and I manage to get about 4 hours on a charge so I have two batteries.

Yes, but would have to ask, why 2 charge controllers to 1 battery or battery bank ?

I think I'll get two.These are only supposed to be good for roughly 300 cycles. That's not even a year of use if used 1x day.And, the batteries have been known to fail prematurely.

It's two batteries. I thought it was a pretty decent deal and am pleased to have a spare to carry in my camera bag.
