Getting the Most Out of Your Hearing Aid Batteries
You could make a strong case that the most important part of your hearing aid is the battery: without it, nothing else works, and if it fails, your hearing fails with it. In this concise guide, we’ll teach you everything you need to know about hearing aid batteries so that you can get the most out of your hearing aids.
How Hearing Aid Batteries Work
Hearing aids take a specific type of battery called zinc-air batteries. Each one has a sticker that covers small holes on the top of the battery. As soon as the sticker is removed, air enters the battery through the holes, creating a chemical reaction that activates the zinc and makes the battery active. After the battery is live, it begins discharging power and reapplying the sticker will have no impact in conserving its life.
Hearing Aid Battery Types
Zinc-air hearing aid batteries come in four standardized sizes, labeled with standardized number and color codes. The four sizes, from biggest to smallest, are:
Each hearing aid makes use of only one of the sizes, and your hearing specialist will tell you which size you need. Also remember that the numbers and colors above are manufacturer independent, but that manufacturers often add additional letters or numbers to its packaging.
Hearing Aid Battery Life
Hearing aid battery life is dependent on numerous factors. Many patients get up to one week of life out of a battery if they use the hearing aid for 12 or more hours a day, but this will change depending on:
- The size of the battery – larger batteries have a longer life.
- The amount of hearing loss – More serious hearing loss requires more power.
- Hearing aid features – wireless capability, noise reduction programs, and multi-channel processing, for instance, call for more power to work.
- Temperature – hot and cold temperatures can diminish battery life.
Your hearing specialist will review all of this with you, and will help you uncover the right balance between hearing aid functionality and battery life.
How to Lengthen the Life of Your Hearing Aid Batteries
You can effortlessly increase the life of your hearing aid batteries with one simple trick. Just after you remove the sticker to activate the battery, wait 5-7 minutes before placing the battery into your hearing aids. By removing the sticker and laying the battery flat side up for several minutes, air is able to properly activate the battery before you start making use of it, which extends its life.
A couple of other tips:
- Keep the batteries away from coins, keys, or other metal items that could short the battery.
- When the hearing aid isn’t being used, turn it off and store it with the battery door open. If you don’t anticipate using your hearing aids for a long period of time, remove the batteries entirely.
- Unopened batteries can last for many years; nevertheless, newer batteries are preferred because each year that goes by reduces the life of the battery.
- Store your batteries at room temperature. This rule is so crucial that the next section is dedicated to the topic.
How to Store Your Hearing Aid Batteries
There’s a dangerous myth out there advocating that storing your batteries in the refrigerator extends their life. This is not only mistaken; it produces the opposite effect!
The thinking behind storing your batteries in the refrigerator is that the cold temperature will slow down the discharge of power. While this may be technically true, the amount of power you will save will be minimal, and the undesirable effects of moisture will produce far greater negative consequences.
Storing zinc-air batteries in a cold environment allows micro condensation to form in an on the battery, resulting in corrosion and a high risk of premature failure. Consequently, for optimal performance, simply keep your batteries away from extreme hot or cold temperatures and store at room temperature.
Maintaining Your Hearing Aid Battery Supply
Once you determine how long your batteries last, on average, you’ll want to keep a month’s supply. If your batteries last 1 week, and you make use of 2 batteries (1 for each hearing aid), then you’ll end up using approximately 8 per month. Simply set 8 as your reorder target, and once you consume your stock down to 8, order another pack. Alternatively, you may want to look into the price savings associated with bulk purchases and maintain a supply that lasts longer than one month.
