How long should my hearing aid battery last?
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.
What is the best way to store hearing aid batteries
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.
What is the purpose of the tab on my Zinc 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. Do not remove the tab 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.
