Hearing Aid Batteries
Hearing Aid Battery Sizes
Hearing aid batteries come in sizes 10, 13, 312 and 675. To identify the size, most manufacturers use an industry standard color code on their zinc air tabs and packaging. Manufacturers often place letters before or after the battery size to designate their factory reorder number. For instance, 13A or R13A are both size 13 batteries.
Hearing Aid Battery Tabs
Do not remove the tab until you are ready to use the battery! A zinc air battery uses air outside the battery as a source of power. The factory applied tab seals the air holes in the battery and ensures freshness until you are ready to use the battery. To activate the battery, you simply remove the tab. After removing the tab, wait about one minute prior to inserting the battery into your hearing aid. This allows sufficient time for the air to enter and activate the ingredients. Replacing the tab when the battery is not in use will not extend the battery life.
Hearing Aid Battery Life
Battery life is determined by the type and amplification of your hearing aid as well as the hours you wear your hearing aid. Your hearing care professional can tell you the battery life you can expect.
Hearing Aid Battery Storage
You should store your hearing aid batteries at room temperature. Avoid storing your 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. Store and discard batteries in places that cannot be reached by infants, children or pets. If a battery is swallowed, see a doctor immediately. For recommended treatment, 24-Hour National Battery Ingestion Hotline at 1-800-498-8666.
Hearing Aid Battery Disposal
Batteries that have been fully discharged can be thrown in your regular trash.
