3 Double A (AA) Batteries. I use pretty cheap batteries and they are still working well for me

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

It uses three watch batteries. They are available at a battery store. Not available everywhere, too specialized.

I believe it was AA batteries. We gave it as a gift, but they no longer have it, as my nephew broke it within a few months time.

It uses the 3v 123 batteries, but I returned my system, due to lack of instructions and customer support. It is a cheap Chinese system that would not work right.

It uses CR2032 batteries, a very common calculator battery. We usually get a whole bunch of them since so many small devices around the house use them.

Hello, This model specifically uses a CR-2032 battery. If you are unfamiliar with them they are the flat round batteries about the size of a dime just a bit bigger in diameter and a bit thicker than a dime.

It uses a CR123 battery. These batteries are expensive, mainly used in photography. I suggest purchasing rechargeable batteries from Surefire.

It uses AA batteries, I suggest getting rechargeable ones. Amazon brand ones are great, they are actually second generation Sanyo.

It uses the 9 volt batteries, you could use rechargeable 9 volt if you wanted to and they were available.

It uses one battery of two battery types. It uses either a standard 1.5 volt type AA battery available at local stores or a 3.6 volt type 14500 Battery that is rechargeable and available from Amazon with charger. Rechargeable AA batteries can be used and are available at many stores. I use the AA battery and get good brightness and life. The 14500 would probably be brighter but it is a specialty battery.

I bought this as a gift and I really don't remember what batteries it takes. Sorry I wasn't more help.

My guess is that you can find these batteries from any battery store. It uses almost classic type batteries
