What type of battery do they need to operate?

Candles use the CR2032 battery. Best to buy online through Amazon to have extras rather than the local store.

You can only operate with 9volt batteries. (square batteries). Don't waste your money mine doesn't work anymore. I have changed the battery and nothing. Lasted 4 months.

I just got them and have not looked at the type of battery it uses, what I can tell you is that they are not very bright, maybe in case of a blackout they might be useful but otherwise they don't light very much.

No they use a small battery. The BenQ work considerably better than a rechargeable after market brand I bought.

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.

The minimum requirement is AA Batteries. Otherwise, your battery choice is limitless.

D batteries. They seem to last a long time. Also when electric is available you can plug it in. Hope that helps. :)

Agreed on AA batteries. I do a bit of international photography and can always find AA batteries. It's impossible to find specialized batteries in most of Africa and Latain America, and a charging unit for a specialized battery is just more gear to lug around, with the risk of loss.

Batteries are built in and rechargable.If they go bad you can replace them.

No battery required. They plug into an electrical outlet. The cord is about 6 yo 8 feet long. Hope this helps.

They don't require a battery in general. Just insure that the Head unit you are using to push them puts out a suitable amount of power. 50 watt RMS would be perfect for these.

The ones I had were solar and so far as I know did not have a battery, If it does, there is no way to access it. I no longer use these because they don't work anymore, as the frequency has been changed.

Only one battery is required. I'd suggest that you get a lipo battery though.

They take a certain type of watch batteries, mine haven't died yet and I've had mine for a year

You could use a Lith battery. When you get the unit test it immediately. The unit I received had a defective manual function.

Amy, They don't take batteries. They require a standard household power connection, normally 115v in the US.
