Description says two different things. On top it says needs 3 - 1.5v AA batteries and on the bottom it says a 9v battery is required. Which one is it?

It requires three AA batteries. The battery holder is encorporated and attached to the bottom of the printed circuit board

The one I have uses 3x AA batteries. I'm not sure if there are different models.

Yes 2 AA batteries are required. I have 2 sets of rechargeable NiMH and a charger. Works great!

I am 99% sure it is 4 AA batteries. I will check when i get home and let you know if it is any different. But I know I did not need special batteries. It was either 4A of two D batteries. Hope this helps.

My First Alert CO605 uses two AA batteries not a 9V. The battery cover opens from the front-top by pulling out and down.

It takes one AA battery. You can buy them just about anywhere. What's the problem?

I'm sorry, but I don't remember. I think it was the AA batteries as I do not remember having to buy a 9v. I gave as a gift.

I think it's a typo, this model which I own takes two (2) ordinary D batteries.There are lots of items listed on amazon that have glaring inconsistencies in their listed descriptions.

We had this about 6 years ago and I cannot remember which batteries it takes. Either AA or AAA.

It definitely is powered by a battery but I do not recall if it came with one. I seem to think it requires a 9v. Sorry that I could not be sure.

I was surprised to find that the 2 motion detectors in the HA-300 kit that I received on 10/15/2015 are powered by 2 AAA batteries. The instructions still say 9 volt. So far seems to work as advertised (40 feet and 110 degrees). 9 volts down to 3? Wonder how long they will last? Much easier to change than 9 volt.

The listing is wrong and I've sent a note to Amazon about correcting that. It comes with 4 Sony AA batteries (non-rechargeable).

I'm not the seller but when I read the description it says no batteries. Mine came in a kit.

It uses 3 AAA batteries not 9V. AAA's are 1.5v per battery. It uses photo-electric technology.

A 9v battery was included with mine, although a cheap chinese brand. But it has worked well so far, about 1hr plus of occasional usage and a complete check of a 3500 sq/ft business.
