Symbol of rechargeable hearing aid battery charging.

Stressing about running low on batteries is something you shouldn’t have to do with rechargeable hearing aids, but when you depend on this technology, it may make you a little anxious. Do rechargeable hearing aids work, and do they work as well as advertised?

Those questions are understandable, as is the accompanying anxiousness. A hearing aid is often as necessary for the enjoyment of a television show or a movie as it is for a trip to the supermarket or any other part of day to day life. It’s essential that a piece of technology functions correctly and reliably, especially when it impacts so many facets of life.

How Do I Know What Type of Battery 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 can usually be distinguished by a battery door on the device, are rechargeable, but the batteries may need to be replaced every now and then. 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. The dependability of these devices has increased considerably in the last few years, as battery technologies have advanced. And, like any other electronic device, however, there are some easy maintenance procedures that users can follow to improve the dependability of their rechargeable hearing aids.

  • Be Careful of Wires: Either the hearing aid itself or the charging station will have some type of wire element on most hearing aids. Being careful of these wires is crucial for hearing aid users; 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 Clean and Dry: No matter how often you use or do not use your hearing aids, they have plenty of opportunity to collect moisture, debris, and dust. Your hearing aid may not fully charge if it is exposed 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.
  • 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 consistently store your hearing aids on their charging station. Charging a battery that is not totally drained does not diminish long-term battery life. As a matter of fact, you can actually increase the battery life by making sure your hearing aids are charging while not in use. A simple reminder, for many people, to charge their device when it’s not used, is to put the charging station on a table beside their bed.

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 should not need to worry about changing those batteries. Simply continue recharging your hearing aids as long as necessary.

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

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

Non-Use For Long Periods

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. If, for example, you know that you won’t be wearing your hearing aids for a few weeks or months, you can simply unplug the charger and store your hearing aids in a dry and cool spot.

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

Keep it Charged Every Day

For most individuals, and for everyday use, charging your hearing aids once per day should be enough for all of your requirements. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours per day.
