Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are designed so that you’ll have to stress less about losing battery power, but the technology may also make you a little nervous when you depend on your devices to hear. Do rechargeable hearing aids work, and do they work as well as advertised?

The anxiety is understandable and so are the question you might have. A hearing aid can be a necessary element of one’s day-to-day life, as necessary for a quick trip to the grocery store as they are for the enjoyment of a television show or movie. It’s essential that a piece of technology functions properly and reliably, especially when it impacts so many aspects of life.

How Do I Know What Type of Battery I Have?

Most modern hearing aids have rechargeable batteries by default, so if you bought your hearing aids recently it’s likely that your hearing aids will have one of two battery types. Silver-zinc batteries, which have a battery door on the back, are rechargeable, but the batteries might have to be replaced every so often. A Lithium-ion battery, however, will last throughout the life-cycle of the hearing device and, due to this, those devices will not have that telltale battery door.

How to Care For Your Rechargeable Hearing Aid

For the most part, rechargeable hearing aids do work, and they work well. As battery technology has improved in the last several years, the dependability of these devices has increased significantly. In order to improve reliability, however, there are a few maintenance steps users can take as they would with any other electronic equipment.

  • The Charging Station is Where Your Hearing Aids Should be Kept: If you regularly store your rechargeable hearing aids on their recharging station you can extend the life of your battery. Charging a battery that is not completely drained does not shorten the long term life of your battery. As a matter of fact, making sure that your hearing aids are charging when not in use can actually benefit your long-term battery life. A simple reminder, for most people, to charge their device when it’s not in use, is to set the charging station on a table near their bed.
  • Be Mindful of Wires: Most hearing aids will contain a wire element of some kind, either on the charging station or on the hearing aids themselves. Most hearing aid users are counseled to be aware of these wires; the connection that allows 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 abundant opportunity to gather moisture, debris, and dust. Any combination of these three things can undercut the capacity of your battery and can hinder charging as much as it needs. When connecting your hearing aid to your charging station, as with any other time, it’s crucial to keep your device clean.

How to Change 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 be concerned about. Your hearing aids can then be simply charged as long as needed.

However, you will want to occasionally change the batteries if you have a hearing aid that uses silver-zinc batteries. The lifespan of your battery can be improved by changing them in the correct way. Because of this, hearing professionals suggest the following:

  • Make sure you have a dry, room temperature place to store your batteries.
  • Make sure you wash your hands before replacing your hearing aid batteries.
  • Don’t get rid of any packaging or plastic tabs until you’re ready to use batteries.
  • Ensure that your battery compartment is free of moisture and clean.
  • Five minutes before removing any tabs that may be attached let the batteries sit at room temperature.

Non-Use For Long Periods

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

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

Rechargeable for Everyday Use

For most individuals, and for everyday use, charging your hearing aids once a day should be adequate for all of your needs. A lithium-ion battery, for example, will typically require just 3-4 hours to charge sufficient battery power for a 24 hour period.

Do rechargeable hearing aids work? Not only do they work, but rechargeable hearing aids will probably become a lot more common and dependable as the technology continues to develop. To see all the different models, get in touch with your local hearing aid retailer.
