Symbol of rechargeable hearing aid battery charging.

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

Those questions are understandable, as is the accompanying stress. A hearing aid can be a necessary element of one’s everyday life, as necessary for a simple visit to the grocery store as they are for the enjoyment of a television show or movie. It’s important that a piece of technology works properly and reliably, especially when it affects so many aspects of life.

What Type of Battery do I Have?

By default, most modern hearing aids have rechargeable batteries, so if you purchased 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 the batteries might need to be replaced every so often. 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 advanced in the last several years, the reliability of these devices has increased significantly. In order to improve dependability, however, there are some maintenance measures users can take as they would with any other electronic device.

  • The Charging Station is Where Your Hearing Aids Should be Stored: If you regularly store your rechargeable hearing aids on their recharging station you can extend the life of your battery. Charging a battery that is not completely drained does not diminish long-term battery life. Actually, you can actually increase the battery life by making sure your hearing aids are charging when not in use. A simple reminder, for many people, to charge their device when not used, is to put the charging station on a table next to their bed.
  • Keep Your Hearing Aids Clean and Dry: No matter how often you use or do not use your hearing aids, they have plenty of occasion to accumulate 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 crucial to keep your device clean.
  • Be Careful of Wires: Either the charging station or the hearing aid itself will have some type of wire element on most hearing aids. Most hearing aid users are counseled to be aware of these wires; 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 Change a Rechargeable Battery

If you have lithium-ion batteries, they should last as long as your device does. As a result, you shouldn’t have to worry about changing those batteries. Simply continue recharging your hearing aids as long as necessary.

Hearing aids that depend on silver-zinc batteries, however, might need new batteries occasionally. Switching batteries in the correct way can help increase the lifespan of your hearing aids. Because of this, hearing professionals recommend the following:

  • Make certain you have a dry, room temperature place to store your batteries.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Five minutes before taking off any tabs that might be attached let the batteries sit at room temperature.
  • Until you’re ready to use the batteries, don’t remove the plastic tabs or packaging.
  • Before changing batteries, make sure you wash your hands.

Non-Use For Long Periods

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 manner to store your devices. If, for instance, you know that you will not be using your hearing aids for several weeks or months, you can just unplug the charger and store your hearing aids in a cool and dry place.

If your hearing aids use silver-zinc batteries, you might also consider leaving the battery door open in order to stop moisture from corroding your batteries.

Keep it Charged Every Day

All your basic requirements should be satisfied if you charge your hearing aids once a day. A lithium-ion battery, as an example, will typically require only 3-4 hours to charge adequate battery power for a 24 hour period.
