Zinc-Air cell is a term used to define a battery with zinc as one electrode and air as the other, which saves carrying one electrode around as air can be collected, as it?s needed.
These cells have a high capacity for their volume and have replaced silver and mercury cells for use in hearing aids. Super long life hearing aid cells are what they are known for.
As supplied, with an adhesive tab, they have a long shelf life. As soon as the tab is removed, air is allowed into the cell and the cell begins to self-discharge. Whether it is used or not, its shelf life will then be about four months. Zinc-Air cells offer very good value for money because of the quantities used in hearing aids.
