Rechargeable Hearing Aids, do They Actually Work?

Rechargeable hearing aids are manufactured so that you’ll need to stress less about running low on batteries, but the technology might also make you a little concerned when you depend on your devices to hear. Do rechargeable hearing aids work as well as marketed or do they even work at all?

The stress is understandable and so are the question you may have. A hearing aid is often as important for the enjoyment of a television show or a movie as it is for a trip to the grocery store or any other part of daily life. When a piece of technology affects so many areas of your life, it’s important that it work correctly and dependably.

What Type of Battery do I Have?

Most modern-day hearing aids have rechargeable batteries by default, so it’s likely if you bought your hearing aids recently, it has one of two types of batteries. Silver-zinc batteries, which can usually be identified by a battery door on the device, are rechargeable, but the batteries may need to be changed every now and then. A Lithium-ion battery, however, will last for the duration of the life-cycle of the hearing device and, as such, those devices will not have that telltale battery door.

Rechargeable Hearing Aids Need Special Care

For the most part, rechargeable hearing aids do work, and they work well. The reliability of these devices has increased considerably in the last few years, as battery technologies have advanced. In order to improve reliability, however, there are a few maintenance measures users can take as they would with any other electronic equipment.

  • Be Careful of Wires: Most hearing aids will have 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 careful of these wires; do not pull or hold your device by these wires as this can damage the connections that enable your hearing aid to charge.
  • Store Your Hearing Aids on The Charging Station: If you regularly store your rechargeable hearing aids on their recharging station you can extend the life of your battery. The long term battery life is not diminished by charging a battery that is not totally drained.In fact, ensuring that your hearing aids are charging when you’re not using them can actually improve your long-term battery life. A convenient reminder, for many people, to charge their device when not used, is to place the charging station on a table beside their bed.
  • Keep Your Hearing Aids Clean and Dry: Your hearing aids will collect debris, dust, and moisture regardless of how often you use them. Your hearing aid might not fully charge if it is exposed to any of these three things. That’s why it’s crucial to keep your hearing aids clean and dry particularly when connecting your hearing aid to its charging station.

How to Replace a Rechargeable Battery

If you have lithium-ion batteries, they will probably last as long as your device does. So replacing those batteries won’t be something you ever have to worry about. Your hearing aids can then be simply charged as long as necessary.

Hearing aids that rely on silver-zinc batteries, however, may call for new batteries now and then. Replacing batteries in the right way can help increase the lifespan of your hearing aids. Because of this, hearing professionals suggest the following:

  • Five minutes before taking off any tabs that may be attached let the batteries sit at room temperature.
  • Keep batteries in a room temperature spot that is also sure to be dry.
  • Ensure that your battery compartment is free of moisture and clean.
  • Remember to wash your hands before replacing your hearing aid batteries.
  • Don’t remove any plastic tabs or packaging until you’re ready to use batteries.

Non-Use For Long Periods

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. If, for example, you know that you won’t be wearing your hearing aids for several weeks or months, you can simply unplug the charger and store your hearing aids in a dry and cool spot.

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.

Keep it Charged Every Day

All your basic 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.
