Miniature zinc-air batteries are button cells that use oxygen in air as a reactant and have very high capacity for their size. Each cell needs around 1cm 3 of air per minute at a 10mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use. Nominal voltage on discharge is 1.2V.Energizer No. 416" (PDF). Datasheet.octopart.com. Archived (PDF) from the original on 5 March 2016 . Retrieved 23 February 2015.
