Caring for your hearing aid battery
Your hearing aid battery or batteries should be stored at room temperature. Avoid storing batteries in hot places since heat will shorten the life of the batteries. Refrigeration is also not recommended.
Batteries should not be carried loose in your pocket or purse. If a battery inadvertently comes into contact with a metal object such as coins or keys the battery may charge, leak or in rare incidences even rupture. To prevent this from occurring keep unused batteries in the original packaging or in a battery holder.
Batteries that have been fully discharged can be thrown in your regular trash. Store and discard batteries in places that cannot be reached by infants or children. If a battery is swallowed, see a doctor immediately. For recommended treatment, call the National Button Battery Hotline collect at 202-625-3333.
