Question 1

Where are these batteries made?

Accepted Answer

The Duracell 312 batteries that I use are made in Elwangen, Germany. They come in a plastic lidded packet of four or six.

Question 2

If the battery is "air activated" will it start  deteriorating as soon as the tab is removed, even without being used?

Accepted Answer

Yes. Absolutely they will start deteriorating as soon as the tab is removed. This is the way the batteries work; they use air as part of the chemical reaction. It's not a problem. Simply leave the tab on until you're ready to use them. Once the tab is removed, the batteries will self-discharge, even if not connected to anything, within a few weeks. I am speaking as a non-scientist who understands science and knows how to look stuff up! Check wikipedia for starters ("zinc air"). Quote from wikipedia: "Miniature cells have high self-discharge once opened to air; the cell's capacity is intended to be used within a few weeks." Note the flaw in the "scientist's" answer: he just assumed, pulling this information out of the "air" (pun intended), that the non-tabbed battery wouldn't discharge much if there were no completed circuit. This false assumption ignores the chemistry of the battery. Once exposed to oxygen, the battery will begin its oxygenation process whether it's connected or not. So unless you live in a vacuum, in which case you'd probably find breathing difficult, just don't pull off the tab until a couple minutes before you're ready to use the battery.

Question 3
