Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are designed so that you’ll need to worry less about running low on batteries, 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 advertised?

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

What Kind of Battery do I Have?

By default, most modern-day hearing aids have rechargeable batteries, 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 can normally be identified by a battery door on the device, are rechargeable, but the batteries may have to be replaced every so often. A Lithium-ion battery, however, will last for the duration of the life-cycle of the hearing device and, due to this, those devices will not have that distinguishing battery door.

How to Care For Your Rechargeable Hearing Aid

For the most part, rechargeable hearing aids do work, and they work well. As battery technology has advanced in the last few years, the reliability of these devices has increased significantly. In order to increase reliability, however, there are some maintenance measures users can take as they would with any other electronic technology.

  • Be Careful of Wires: Most hearing aids will contain a wire element of some kind, either on the hearing aids themselves or on the charging station. Being aware of these wires is important for hearing aid users; the connection that allows the device to charge can be damaged if you pull on or hold it by the wires.
  • Store Your Hearing Aids on The Charging Station: If you regularly store your rechargeable hearing aids on their recharging station you can increase the life of your battery. Charging a battery that is not totally drained does not diminish long-term battery life. In fact, ensuring that your hearing aids are charging when you’re not using them can actually maximize your long-term battery life. A simple reminder, for many people, to charge their device when not in use, is to place the charging station on a table beside their bed.
  • Keep Your Hearing Aids Clean and Dry: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Your hearing aid might not fully charge if it is subjected to any of these three elements. When connecting your hearing aid to your charging station, as with any other time, it’s a must to keep your device clean.

How to Replace a Rechargeable Battery

Lithium-ion batteries should last the lifespan of your device. Consequently, you shouldn’t have to worry about replacing those batteries. Simply continue recharging your hearing aids as long as needed.

However, you will want to periodically replace the batteries if you have a hearing aid that uses silver-zinc batteries. Switching batteries in the right way can help increase the lifespan of your hearing aids. As such, the majority of people who use these hearing aids are counseled to:

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

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 disconnect your hearing aid and put it in a dry cool spot if, for instance, you know you won’t be using them for a few weeks or a month.

Consider leaving the battery door open so you can stop moisture from corroding the batteries if you have silver-zinc 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 very likely become much more common and dependable as the technology continues to develop. To see all the different models, contact your local hearing aid retailer.
