Symbol of rechargeable hearing aid battery charging.

Worrying about running low on batteries is something you shouldn’t have to do with rechargeable hearing aids, but when you rely on this technology, it may make you slightly concerned. Do rechargeable hearing aids work, and do they work as well as marketed?

The worry is reasonable and so are the question you might 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. It’s essential that a piece of technology functions correctly and reliably, especially when it affects so many facets 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 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.

How to Care For Your Rechargeable Hearing Aid

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

  • Keep Your Hearing Aids on The Charging Station: 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. The long term battery life is not diminished by charging a battery that is not fully drained.As a matter of fact, you can actually increase the battery life by making certain your hearing aids are charging while not in use. A convenient reminder, for many people, to charge their device when it’s not in use, is to put the charging station on a table near their bed.
  • Keep Your Hearing Aids Dry and Clean: No matter how often you use or do not use your hearing aids, they have plenty of occasion to gather moisture, debris, and dust. Your hearing aid may not thoroughly charge if it is subjected to any of these three things. When connecting your hearing aid to your charging station, as with any other time, it’s a must to keep your device clean.
  • Be Careful of Wires: Either the hearing aid itself or the charging station will contain some type of wire element on most hearing aids. Being aware of these wires is essential for hearing aid users; do not pull or hold your device by these wires as this will damage the connections that enable your hearing aid to charge.

How to Replace a Rechargeable Battery

Lithium-ion batteries will normally last the lifespan of your device. Because of this, you shouldn’t have to worry about replacing those batteries. Simply keep recharging your hearing aids as long as necessary.

However, you will want to occasionally replace the batteries if you have a hearing aid that uses silver-zinc batteries. The lifespan of your battery can be improved by replacing them in the right way. As such, the majority of people who use these hearing aids are counseled to:

  • Make sure you have a dry, room temperature spot to keep your batteries.
  • Ensure you wash your hands before replacing your hearing aid batteries.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Don’t remove any plastic tabs or packaging until you’re ready to use batteries.
  • Let the batteries sit out at room temperature for at least five minutes before taking off any tabs that might be attached.

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 way to store your devices. Just unplug your hearing aid and put it in a dry cool place if, for example, you know you won’t be using them for several weeks or a month.

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

Rechargeable for Everyday Use

For most people, and for everyday use, charging your hearing aids once a day should be sufficient for all of your needs. 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 more and 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.
