3, size AAA - double checked and opened it up to be sure. Probably good for 20-40 hours.

mn21/23 12volt (its about half the size of a triple a battery. not sure if mine is defective or not, but ive gone through sets of batteries and they don't seem to last or work well. the light it gives off was sufficient, but I wouldn't buy again.

I looked on the battery and there is no information. I don't seem to have the literature that came with it. Sorry.

I have purchased close to 10 of these now. The black box in the pictures is roughly 5.25" X 2.5" X 1". If you plan on junking the black box, the battery is going to be approximately 2.5" X 3" or 2.5" X 2.5". There doesn't seem to be any consistency with the physical size of the battery. Either they are rectangular or square. The 10 that I have purchased have been (3) 3.7V batteries wired in series.

I've opened up the unit and I couldn't find the same battery size to buy. I believe the one that I did find was almost the price of the unit.

I have to admit that I bought the batteries for a tool for size. Forgot to check capacity but it looks like at least 1800 mah. Things have happened which has kept me from using the batteries. Sorry can't be more help. Price is right though

4 or 6 "C" batteries. I can't recall exactly at the moment, but I'm almost certain it's 4. There is also a power adaptor input plug in case you want to mount it near a power source.

Each battery is approximately 6"x8"x8". Four batteries together would occupy less than 1 cubic foot of space (0.9 cubic feet).

4 AA batteries. Maybe it's 2 I don't remember. Either way there is a place in the case for spares.

Ten (10) great little batteries, I Immediately tested mine with a multi-meter and all were in super shape, all ten had excellent voltage.I have already ordered more of another type and they were in super condition too and all tested great.The wrapper may be diffent from the package displayed but the battery is the important part.Good luck and have a great new year.

I'm going into my 4th year with it and the battery is still fine. I use it about 40 times a year for about an hour each time. It's about 10" wide x about 14" tall x maybe 6 to 8" deep. The smaller pack is about 4" wide x 5 or 6" tall. Sorry I can't be more exact, I'm not home with it now to measure it.

I do not remember how many batteries there were as I left them at the school where I taught last year. I bough two pair. Take a little patience to sink all with the same channel but worth it.

To be honest, I don't remember. Go back on Amazon, bring up the account, look at the batteries that you bought and e-mail or call the company that you bought them from & ask them. They are really good about getting right back to you!
