Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are designed so that you’ll need to stress less about running low on batteries, but the technology may also make you a little anxious when you rely on your devices to hear. Do rechargeable hearing aids work, and do they work as well as advertised?

Those questions are understandable, as is the accompanying stress. A hearing aid can be a vital element of one’s everyday life, as necessary for a quick trip to the grocery store as they are for the enjoyment of a television show or movie. When a piece of technology impacts so many aspects of your life, it’s important that it functions correctly and dependably.

What Type of Battery do I Have?

Most modern-day hearing aids are equipped with 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 can normally be distinguished by a battery door on the device, are rechargeable, but every now and then they need to be replaced. A Lithium-ion battery, however, will last throughout the life-cycle of the hearing device and, because of that, those devices will not have that distinguishing battery door.

Rechargeable Hearing Aids Need Special Care

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

  • Be Careful of Wires: Either the charging station or the hearing aid itself will contain some type of wire element on most hearing aids. Most hearing aid users are advised to be aware of these wires; do not pull or hold your device by these wires as this will damage the connections that allow your hearing aid to charge.
  • 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 accumulate moisture, debris, and dust. Your hearing aid might not completely charge if it is subjected to any of these three things. That’s why it’s crucial to keep your hearing aids dry and clean especially when connecting your hearing aid to its charging station.
  • The Charging Station is Where Your Hearing Aids Should be Kept: If your hearing aids have rechargeable batteries, you can extend your device’s battery life by ensuring that you regularly store your hearing aids on their charging station. Charging a battery that is not totally drained does not shorten the long term life of your battery. Actually, you can actually enhance 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 not used, is to put the charging station on a table near their bed.

How to Change a Rechargeable Battery

If you have lithium-ion batteries, they should last as long as your device does. Because of this, you should not have to worry about changing 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 utilizes silver-zinc batteries. Switching batteries in the right way can help increase the lifespan of your hearing aids. Because of this, hearing professionals suggest the following:

  • Don’t eliminate any packaging or plastic tabs until you’re ready to use batteries.
  • Ensure that your battery compartment is clean and free of moisture.
  • Let the batteries sit out at room temperature for at least five minutes before removing any tabs that might be attached.
  • Before changing batteries, be sure you wash your hands.
  • Make certain you have a dry, room temperature spot to store your batteries.

Non-Use For Long Periods

Leaving your hearing aids on the charger over long periods of time is no longer the way to store your hearing aids. Simply unplug your hearing aid and store it in a dry cool spot if, for instance, you know you won’t be using them for several weeks or a month.

If your hearing aids utilize 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 general needs should be met if you charge your hearing aids once per day. A lithium-ion battery, for example, will typically require only 3-4 hours to charge enough battery power for a 24 hour period.

Do rechargeable hearing aids work? Not only do they work, but rechargeable hearing aids will probably become much more common and reliable as the technology continues to improve. Schedule an appointment with your local hearing aid retailer to see all the different models
