Bottom view of the Rayovac 675 [L675ZA] zinc-air battery showing the
positive (+) terminal. Note the six holes in the bottom. These holes
let air into the battery to activate it. That is why it is called a
zinc-air battery.
Once the blue tab (below) is removed the battery starts working (and
thus running down) whether you use it or not.

blue tab covering and sealing the 6 air holes so the battery is not
activated and thus has a long shelf life. The blue tab is the
standard color for all 675-sized zinc-air batteries, no matter who makes
them.
