ReSound Size 312 hearing aid batteries
These disposable zinc-air batteries provide power for hearing aids designed to use the standard size 312 format. Size 312 batteries are identified by their brown colour code, making them easy to distinguish from common alternatives such as size 10, 13 and 675.
Zinc-air technology
The batteries use zinc-air chemistry and remain inactive while the protective tab is attached. Once the tab is removed, oxygen enters the battery and starts the activation process.
Only remove the tab when you are ready to use a battery, as the activation process cannot be reversed.
