Bottom view of the UltraLast No. 13 [UL13HA] zinc-air battery showing the
positive (+) terminal. Note the two 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 orange tab (below) is removed the battery starts working (and
thus running down) whether you use it or not. |

tab covering and sealing the 2 air holes so the battery is not activated
and thus has a long shelf life. The orange tab is the
standard color for all 13-sized zinc-air batteries, no matter who makes
them.
