Choosing The Right Battery For Your Hearing Aid
There are four different hearing aid battery sizes 10, 13, 312 and 675.Manufacturers use an industry-standard color code to identify the battery size. Different battery sizes are used to power different types of devices. In general, the larger the battery the greater the power. You can find which type of battery your device requires by referring to your hearing device’s manufacturer’s manual.Zinc air batteries use air as an active ingredient in fueling the battery. The peel off tab provides a seal that ensures freshness until the time of use. Once you peel or remove the tab off the battery, the air from outside of the battery begins to react with the zinc inside of the battery, this reaction is what charges up or powers the battery. To properly activate the battery, remove the tab and wait one to five minutes to allow air to fill and fully charge the battery, then, insert the battery into your hearing aid. Note: replacing the tab when the battery is not in use will not extend the battery life.When the tab is removed and the battery has been aired up properly, make sure that you are not forcing the battery door closed. Check that the battery is inserted correctly before closing the hearing aid battery door.
Tips and Tricks
- Leave new batteries sealed in their original packages
- Do not remove the tab on your zinc air battery until you are ready to use it
- Store batteries at room temperature
- A fresh battery has more power than an aged battery. Therefore, review expiration dates on the back of battery packages prior to purchase
- Store and discard batteries in places that cannot be reached by infants or children
Things That Affect Hearing Aid Battery Life
Hearing aid batteries typically have a long shelf life (up to three to four years) if stored properly. Hearing aid batteries themselves are sealed by use of a sticker, which blocks oxygen from entering the battery and reacting with the zink inside. When the sticker is removed, oxygen enters the battery through small holes and reacts with he zinc, the battery then becomes “active”. After removing the sticker, waiting one (1) to five (5) minutes (allowing the hearing aid battery to fully charge up) prior to inserting the hearing aid battery into the hearing aid will provide a longer battery life.
