I've read the above and the TSA pages about Lithium batteries, but I'm still confused.
If I understand, a "big" lithium battery, like in a camera or cell phone, can be carried on the plane in the camera or cell phone, right?
But what about small non-rechargeable AA Lithium batteries, like the Energizer E2 ones? Can these be carried onto the plane? Can they be put into checked luggage? In either case do they have to be in the original packages, or in special packaging, or can they be loose?
