Symbol of rechargeable hearing aid battery charging.

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

The worry is understandable and so are the question you might have. A hearing aid is often as necessary for the enjoyment of a tv show or a movie as it is for a trip to the supermarket or any other part of daily life. It’s important that a piece of technology works properly and reliably, especially when it impacts so many facets of life.

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 have a battery door on the back of the device, are rechargeable, but the batteries might have to be changed 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. The dependability of these devices has increased considerably in the last several years, as battery technologies have advanced. In order to improve reliability, however, there are a few maintenance steps users can take as they would with any other electronic technology.

  • The Charging Station is Where Your Hearing Aids Should be Stored: If you consistently store your rechargeable hearing aids on their recharging station you can increase the life of your battery. The long term battery life is not shortened by charging a battery that is not fully drained.In fact, ensuring that your hearing aids are charging when not in use can actually improve your long-term battery life. For lots of people, setting their charging station next to their bed is a convenient reminder to charge the devices when it’s not being used.
  • Keep Your Hearing Aids Clean and Dry: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Your hearing aid may not completely charge if it is subjected to any of these three elements. That’s why it’s essential to keep your hearing aids clean and dry particularly when connecting your hearing aid to its charging station.
  • Be Mindful of Wires: Most hearing aids will contain a wire element of some kind, either on the hearing aids themselves or on the charging station. Most hearing aid users are advised to be mindful of these wires; the connection that allows the device to charge can be damaged if you pull on or hold it by the wires.

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 shouldn’t be something you ever have to worry about. Your hearing aids can then be simply charged as long as necessary.

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

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

Long Periods of Non-Use

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

Think about leaving the battery door open so you can stop moisture from corroding the batteries if you use silver-zinc batteries.

Rechargeable for Everyday Use

All your general requirements should be met if you charge your hearing aids once a day. A lithium-ion battery, for example, will normally require only 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.
