Symbol of rechargeable hearing aid battery charging.

Worrying about losing battery power is something you shouldn’t have to do with rechargeable hearing aids, but when you depend on this technology, it might make you a little anxious. Do rechargeable hearing aids work, and do they work as well as marketed?

The stress is reasonable and so are the question you may have. A hearing aid is often a vital part of one’s day-to-day life, as necessary for a quick visit to the grocery store as they are for the enjoyment of a television show or movie. It’s essential that a piece of technology works correctly and reliably, especially when it impacts so many aspects of life.

How Do I Know What Kind of Battery I Have?

By default, most modern-day hearing aids have rechargeable batteries, so if you got your hearing aids recently it’s likely that your hearing aids will have one of two battery types. Silver-zinc batteries, which can normally be distinguished by a battery door on the device, are rechargeable, but every now and then they need to be replaced. A Lithium-ion battery, however, will not have a battery door because the batteries will last as long as the hearing aid does.

Rechargeable Hearing Aids Need Special Care

For the most part, rechargeable hearing aids do work, and they work well. As battery technology has advanced in the last few years, the reliability of these devices has increased considerably. And, like any other electronic device, however, there are various easy maintenance steps that users can follow to improve the reliability of their rechargeable hearing aids.

  • The Charging Station is Where Your Hearing Aids Should be Kept: If your hearing aids have rechargeable batteries, you can increase the battery life of your device by making sure that you consistently store your hearing aids on their charging station. Charging a battery that is not fully drained does not diminish long-term battery life. In fact, you can actually increase the battery life by making sure your hearing aids are charging while not in use. For lots of people, setting their charging station beside their bed is a convenient reminder to charge the devices when not in use.
  • Be Mindful of Wires: Either the hearing aid itself or the charging station will contain some type of wire element on most hearing aids. Most hearing aid users are counseled to be aware of these wires; the connection that enables the device to charge can be damaged if you pull on or hold it by the wires.
  • Keep Your Hearing Aids Dry and Clean: No matter how often you use or do not use your hearing aids, they have ample opportunity to accumulate moisture, debris, and dust. Your hearing aid may not thoroughly charge if it is subjected to any of these three elements. When connecting your hearing aid to your charging station, as with any other time, it’s essential to keep your device clean.

How to Replace a Rechargeable Battery

Lithium-ion batteries will normally last the as long as your device does. So changing those batteries shouldn’t be something you ever have to worry about. Simply keep recharging your hearing aids as long as needed.

Hearing aids that depend on silver-zinc batteries, however, may require new batteries once in a while. The lifespan of your battery can be increased by changing them in the correct way. Because of this, hearing professionals suggest the following:

  • Ensure you wash your hands before changing your hearing aid batteries.
  • Five minutes before removing any tabs that might be attached let the batteries sit at room temperature.
  • Make certain you have a dry, room temperature place to keep your batteries.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Don’t remove any packaging or plastic tabs until you’re ready to use batteries.

Long Periods of Non-Use

If you are planning not to use your hearing aids for long periods of time, leaving them on the charger may no longer be the best manner to store your devices. Simply unplug your hearing aid and put it in a cool dry spot if, for example, you know you won’t be wearing them for a few weeks or a month.

If your hearing aids use silver-zinc batteries, you might also think about leaving the battery door open in order to prevent moisture from corroding your batteries.

Rechargeable for Everyday Use

All your general needs should be met if you charge your hearing aids once a day. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours per day.

Do rechargeable hearing aids work? Not only do they work, but rechargeable hearing aids will most likely become much more common and reliable as the technology continues to develop. Make an appointment with your local hearing aid retailer to see all the different models
