Hearing Aid Batteries

No matter what style of hearing aid you choose, your new device will need batteries to function. Most hearing aids use one of five battery sizes. Smaller devices require smaller hearing aid batteries, which have a shorter lifespan (2–4 days on average). Larger hearing aid styles use bigger batteries, which offer a longer lifespan (7–14 days on average).

Buying hearing aid batteries in Alexandria will become a part of your regular routine quickly as you adapt to life with hearing aids. Each of the five types of hearing aid batteries are color- and number-coded to make them easy to buy.

Types of Hearing Aid Batteries

  • Zinc-air—These disposable batteries are the most commonly used method for powering hearing aids. Unlike other kinds of batteries, zinc-air technology requires oxygen to produce power. These batteries need to be activated by pulling a tab or removing a protective seal, depending on the brand. There are a few types and sizes of zinc-air batteries. You can purchase these batteries at most drug stores, online or from your audiologist’s office.
  • Rechargeable—There are rechargeable versions of most disposable zinc-air battery types that can be used with many of today’s hearing aids. You will likely need a few backups on hand to stay prepared and powered throughout the day. While these require a larger upfront investment, they typically offer better long-term value and are a more eco-friendly option than their disposable counterparts. To find out about rechargeable battery options for your hearing devices, talk to your audiologist.
  • Extended life—Lyric hearing aids have revolutionized the world of hearing device batteries. While the average lifespan of disposable batteries is about one week, implantable Lyric devices last up to 16 weeks. Once the batteries on Lyric hearing aids run out, you simply dispose of the device and get a new one implanted by your audiologist. For those who lead active, busy lifestyles, extended battery hearing aids are a great option.

Caring for Hearing Aid Batteries

Hearing aid batteries need to be properly stored and cared for in order to perform at their best. Take a look at these guidelines to ensure you’re getting the most out of your batteries:

  • Store batteries in a clean, dry, room-temperature location. People tend to store batteries in the fridge to extend their life, but this actually does more harm than good. Batteries will last longer if they’re stored between 50 and 77 degrees in a low-humidity, low-moisture area.
  • Allow batteries to absorb oxygen for 60 seconds or longer before use. Zinc-air batteries need oxygen to produce power. If they don’t get fully charged before they’re inserted into your devices, they won’t power your devices at their full potential.
  • Keep batteries away from metallic objects. Contact with metal can cause your batteries to malfunction or lose charge. Always keep your batteries away from objects like keys and coins and ensure you don’t store them in a metal cabinet or shelving unit.
  • Clean your batteries and battery compartments regularly. Dirty or moist batteries, battery compartments and battery contacts often result in poorly functioning hearing aids. Make sure you wipe these sections of your hearing devices down daily with a dry, soft cloth as part of your daily cleaning and maintenance routine.
  • Open your hearing aid battery compartments overnight. This offers two benefits: first, it will help conserve power, increasing the value of your batteries; second, it will release any moisture that’s being retained in the battery compartment, which is essential to good hearing aid maintenance.
