Symbol of rechargeable hearing aid battery charging.

Stressing about losing battery power is something you shouldn’t have to do with rechargeable hearing aids, but when you rely on this technology, it might make you slightly nervous. Do rechargeable hearing aids work, and do they work as well as marketed?

Those questions are understandable, as is the accompanying anxiety. A hearing aid is often a vital element of one’s day-to-day life, as necessary for a quick visit to the grocery store as they are for the enjoyment of a movie or television show. It’s essential that a piece of technology functions correctly and dependably, especially when it impacts so many aspects of life.

How Do I Know What Kind of Battery I Have?

Most modern-day hearing aids are equipped with rechargeable batteries by default, so if you got 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 of the device, 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.

Rechargeable Hearing Aids Need Special Care

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

  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect debris, dust, and moisture regardless of how often you use them. Any combination of these three elements 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 a must to keep your device clean.
  • 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 aware 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.
  • 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. The long term battery life is not diminished by charging a battery that is not fully drained.In fact, you can actually increase the life of the battery 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 used, is to put the charging station on a table near their bed.

How to Replace a Rechargeable Battery

Lithium-ion batteries will normally last the as long as your device does. So replacing those batteries won’t be something you ever have to be concerned about. Simply keep recharging your hearing aids as long as needed.

However, you will need to occasionally replace the batteries if you have a hearing aid that utilizes silver-zinc batteries. Replacing batteries in the right way can help improve the longevity of your hearing aids. As a result, most people who use these hearing aids are counseled to:

  • Before replacing batteries, make sure you wash your hands.
  • Until you’re ready to use the batteries, don’t remove the plastic tabs or packaging.
  • Confirm that your battery compartment is clean and free of moisture.
  • Keep batteries in a room temperature place that is also sure to be dry.
  • Five minutes before taking off any tabs that might be attached let the batteries sit at room temperature.

Long Periods of Non-Use

Keeping your hearing aids on the charger for extended periods of time is no longer the best way to store your hearing aids. If, for instance, you know that you will not be wearing your hearing aids for several weeks or months, you can simply unplug the charger and put your hearing aids in a dry and cool place.

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

Rechargeable for Everyday Use

All your general requirements should be satisfied if you charge your hearing aids once per day. A lithium-ion battery, as an 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 very likely become more and more common and reliable as the technology continues to improve. To see all the different models, get in touch with your local hearing aid retailer.
