Did you know that hearing aid batteries are activated by oxygen?
Hearing aids commonly use a type of battery known as a zinc-air battery. These small silver discs must be recycled or discarded after use, and are not rechargeable. Unlike regular “everyday” batteries, zinc-air hearing aid batteries need oxygen to provide power. They get this oxygen when a small sticker on the back of the hearing aid battery is removed, exposing the zinc inside the battery to air, and activating the battery. Note that once the sticker has been removed, the activation process cannot be stopped. Re-applying the sticker won’t help, unfortunately. So make sure you are ready to use the battery before you remove the sticker.
Change your hearing aid batteries in three simple steps
Depending on your hearing aid style, how long you wear your hearing aids each day, and if you do a lot of wireless streaming to your hearing aids, the batteries can last anywhere from three days to up to a couple of weeks. It’s easy to change your batteries, and your Beltone hearing aids will even help you get started. When the batteries begin to get low, an intermittent beeping sound will notify you that it is time to replace them. When you hear that low battery sound, follow these three easy steps to install new ones and continue with uninterrupted hearing:
- Remove the batteries from the package and peel the sticky tabs off them. Hearing aid batteries come in five different sizes with universal color coding. So be sure that you have the right battery size before you open the package.
- Wait a full minute to allow the new batteries to absorb oxygen and activate. Zinc-air batteries are designed with fine holes and a filter, so your batteries should be exposed to air for 60 seconds prior to installing, to ensure they will have full power in your hearing aids, and last as long as they’re supposed to.
- Remove the old batteries and place the new batteries into the slots with the positive side up. Hearing aid batteries have a smooth, or positive, side; and a raised, or negative, side. The proper placement for the batteries is with the negative side down, so the smooth surface is all you see. If you have installed the batteries correctly, you should be able to close the doors of the battery compartments smoothly and easily. If it seems difficult to close them, check to see if you may have accidentally installed the batteries incorrectly.
And, don’t forget proper care for your hearing aid batteries
By remembering a few different characteristics about your hearing aid batteries, you can help them retain power for a longer time:
- Both heat and humidity can shorten the life of zinc-air batteries, so store them at room temperature.
- Interaction with other metal items can short-circuit your hearing aid batteries, so store them away from keys and coins.
- For optimal performance and battery life, open the battery compartments whenever you’re not wearing your hearing aids. This will limit battery drain and prevent moisture buildup.
- Turn your hearing aids off when they are not in use.
And here’s a tip. When changing your batteries, place a hand towel on the surface of the table. That way, if the battery drops, it won’t bounce off the hard surface, and it will be easy to find. Understanding zinc-air batteries, learning to replace them efficiently, and facilitating long battery life will help give you the best hearing experience possible from your Beltone hearing aid. And be sure to look for the mercury-free symbol on Beltone batteries.
