Rechargeable Hearing Aids: Do They Really Work?

Rechargeable hearing aids are designed so that you don’t have to worry about losing battery power, but the technology might intimidate you, if you don't know how it works

Hearing aids can be very important for the enjoyment of a movie, going to the grocery store and many parts of daily life. It’s important that it works correctly and dependably. 

How Do I Do Know What Type of Battery I Have?

Most modern hearing aids have rechargeable batteries, so if you got yours recently it’s likely that your hearing aids have one of two battery types. Silver-zinc batteries, which have a battery door on the back of your device, are rechargeable but need to be replaced occasionally. A lithium-ion battery doesn’t have a battery door, as the batteries will last for as long as the hearing aid does. 

Rechargeable Hearing Aid Care

Rechargeable hearing aids do work and work well. These devices have become much more reliable in recent years, as battery technology has improved. As with any electronic device, there are some maintenance tasks that users should carry out to improve the dependability of a rechargeable hearing aid:

  • Keep your hearing aid in the charging station: If you store your rechargeable hearing aid in the proper charging station, you can improve the battery life. The long-term life of the battery is not diminished by charging a battery that hasn’t completely drained. You can actually improve the lift of the battery by making sure it is charging when it’s not in use. You can keep your charging device next to the bed to make it easy to remember to charge the devices when they’re not in use. 
  • Be careful of wires: The charging station or the hearing aid will have some kind of wire element on most hearing aids. Most hearing aids users are told to be aware of these wires, as the connection that lets the device charge can easily be broken if the wire is pulled. 
  • Keep your hearing aids clean and dry: Your hearing aids will collect debris, dust and moisture. All these elements can make your battery less efficient and can obstruct the ability to charge. Therefore, you should keep your hearing aids clean and dry, especially when you connect the device to the charging station. 

How To Replace A Rechargeable Battery

Lithium-ion batteries should last as long as your hearing aids, so you don’t need to change these batteries. Your hearing aids can just be recharged. However, if you have silver-zinc batteries in your hearing aid, these do need to be changed from time to time. You can help your battery to last longer by replacing them in the right way:

  • Don’t remove any of the plastic tabs or packaging from your hearing aid battery until you are ready to use the batteries. 
  • Before fitting a new battery, let the new one sit at room temperature for about five minutes before you take off any tabs. 
  • Make sure you always wash your hands before you change your hearing aid batteries. 
  • Keep the batteries in a room temperature spot that is certain to be dry. 
  • Make sure that you keep the battery compartment free of moisture and clean

Long Periods of Non-Use

If you are planning to not use your hearing aid for a long period of time, leaving them on their charging station might not be the best way to store them. For example, if you know that you will not be wearing your hearing aids for several weeks or even months, then you should just remove the charger and store the device somewhere cool and dry. 

You should also leave the battery door open so you can stop moisture from causing corrosion of the batteries if your device has silver-zinc batteries. 

Rechargeable For Everyday Use

All of your general hearing needs should be met if you charge your hearing aids once a day, such as overnight, while you’re sleeping. A lithium-ion battery, for example, should normally need between three and four hours to charge in order to have enough battery power for you to use it for 24 hours. 

Do rechargeable hearing aids work? They do work and are becoming more common all the time. If you want to learn more, book an appointment with an audiologist to discuss whether these would be a good option for you.
