Hearing Aid Batteries

While there are rechargeable hearing aids available, most hearing aids require hearing aid batteries. There are various hearing aids options, and which ones you need, how long they last, and other care concerns will depend on the hearing aids you own.

Hearing Aid Batteries At Heroes Of Hearing

At our Heroes of Hearing clinic, our hearing instrument specialist often recommends Rayovac hearing aid batteries. While you can find other manufacturers of hearing aid batteries, not all of them deliver the long-lasting power that Rayovac batteries offer.

You can purchase Rayovac hearing aid batteries from our hearing clinic, and our hearing instrument specialist can help you replace the batteries in your hearing aids.

  • Size 675 – Average 9-20 days
  • Size 13 – Average 6-14 days
  • Size 312 – Average 3-10 days

If you have been noticing that your hearing aid batteries are not lasting as long as they should according to the above averages, there may be something wrong with your hearing aid. Contact us to have our hearing instrument specialist check your device and make any necessary repairs.

When you need to dispose of your hearing aid batteries once they are dead, it is best to recycle them rather than throw them away with the rest of your trash. Electronic stores and designated recycling centers will often accept used hearing aid batteries for safe disposal.

Hearing Aid Batteries Care Tips

Hearing aid batteries are not exactly like your run-of-the-mill batteries. To help you preserve their lifespan and store them properly, follow the care tips below:

Remove the tab only when ready to use – Hearing aid batteries are zinc-air batteries, which are activated when exposed to air. The tab sticker on the back of each battery keeps the air out and allows the hearing aid battery to be stored for 3 years before it expires. However, once you remove the tab, the battery life starts. Placing the tab back on the battery will not stop the battery life from running, so be ready to use it once the tab is off.

Allow the hearing aid battery time to breathe – Since these hearing aids are air-activated, it is best to give your hearing aid batteries exposure to air. A good practice to follow is once you remove the tab from a hearing aid battery, let the battery sit and take in oxygen for one minute before you place it in your hearing aid. This time allows the battery to turn on fully.

Keep hearing aid batteries in the pack – As hearing aid batteries are smaller than a dime, they can become easily damaged and/or lost. As batteries like Rayovac come in convenient packages that securely contain your hearing aid batteries until you need them, it is best if you keep them in their container. Otherwise, things like loose change, keys, and other items can damage your hearing aid batteries and potentially pull the tab off them.

Open hearing aid battery door nightly – To help extend the life of your batteries and hearing aid, be sure to open the hearing aid battery doors every night as you put them away. While this step will not stop your batteries from running, it can prolong the lifespan of your batteries and protect your hearing aids from needing to run continuous electrical current.

Keep hearing aid batteries at room temp – When it comes to storing your spare hearing aid batteries, it is best to keep them to room temperature in a dry place, out of sunlight. You do not need to keep your hearing aids in the refrigerator, as the cold does nothing to keep your batteries in better condition. In fact, placing them in a cold place introduces the risk of moisture.

Avoid contact with moisture – One of the fastest ways to kill a hearing aid battery is with moisture. Not only is moisture a risk to your stored batteries, but it also poses an active risk to the batteries in your hearing aids. Store them in a room-temperature, dry place, and your spare hearing aid batteries can last for 3 years while inactive.

Keep hearing aid battery contacts clean – Sometimes hearing aid batteries can corrode, damaging the contacts on your hearing aids. This corrosion can drastically reduce the life of not only your batteries but also your hearing aids. Check regularly that your battery contacts are clean and wipe them down.
