The ignite switch. You don't really have to think about it, but it's in there. I think you unscrew the actual button to get to it.

Not regular AA batteries. It comes with an adaptor, if I am not mistaken, for 3 AAA batteries.

The camera uses two inexpensive, readily available AA batteries. Also, the extra weight of the batteries make it a little easier to steady the camera when taking pictures.

AA batteries are used. I keep the main unit plugged in via the power adapted that came with it, but if you're looking for portability of the base unit then use the AA batteries.

AA batteries...can't remember though if they came with the unit or if I had to supply.

The military model uses a CR123a battery. There may be a model of this that DOES work with a AA battery, but I am not aware of the exact model number

It uses AAA batteries. When I bought it I thought it used AA. Would not have bought it if I had known.

No, you can not use AA batteries. I don't know if you can purchase an extra battery. So far battery life has not been an issue for me.

They are your standard rechargable AA batteries. You can find them at any home improvement center or hardware store.

I've never tried a AA battery but I can tell you the battery this comes with is nearly twice and size as far as thickness goes and about 20% longer so not sure a AA would work. The battery this calls for is an 18650. You can find them for around $10-$15 for 2 plus a charger (since they are rechargeable). Much better value than a AA anyway. Even if your AA are rechargeable they won't hold as much power as these. Hope this helps.

As in not a standard AA or D cell. It is a small almost square battery, non-standard.

It uses any regular double "A" (AA) battery. One of the many features I really like about it.

Yes, that is on of the major advantages of this camera, it uses AA batteries.

The battery is the square rechargeable kind, not AA. You charge battery by plugging the camera in, you can also charge it if you attach it to your computer and it is on. You can also buy a separate charger where you take it out of the camera and place it into the unit.

Yes, You can use AA batteries but make sure they are lithieum or they will not last long. The re-charge batteries are the best.
