Symbol of rechargeable hearing aid battery charging.

Worrying about losing battery power 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 concerned. Do rechargeable hearing aids work, and do they work as well as marketed?

Those questions are reasonable, as is the accompanying stress. A hearing aid can be a vital part 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 affects so many facets of your life, it’s essential that it work correctly and reliably.

How Do I Know What Type of Battery I Have?

By default, most contemporary hearing aids have rechargeable batteries, 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 identified by a battery door on the device, are rechargeable, but every so often they need to be replaced. 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 telltale 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 improved in the last few years, the dependability of these devices has increased substantially. In order to increase dependability, however, there are some maintenance steps users can take as they would with any other electronic device.

  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Your hearing aid might not thoroughly charge if it is exposed to any of these three elements. That’s why it’s crucial to keep your hearing aids dry and clean particularly when connecting your hearing aid to its charging station.
  • Be Careful of Wires: Either the charging station or the hearing aid itself will have some kind of wire element on most hearing aids. Most hearing aid users are advised to be careful of these wires; the connection that enables the device to charge can be damaged if you pull on or hold it by the wires.
  • The Charging Station is Where Your Hearing Aids Should be Stored: If your hearing aids have rechargeable batteries, you can increase the battery life of your device by ensuring that you regularly store your hearing aids on their charging station. Charging a battery that is not fully drained does not reduce long-term battery life. In fact, you can actually improve the life of the battery by making certain your hearing aids are charging while not in use. For lots of people, placing their charging station next to their bed is a convenient reminder to charge the devices when it’s not being used.

How to Change a Rechargeable Battery

Lithium-ion batteries should last the as long as your device does. So changing those batteries shouldn’t be something you ever have to worry about. Simply continue recharging your hearing aids as long as necessary.

However, you will want to occasionally change 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 such, most people who use these hearing aids are counseled to:

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

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

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

Rechargeable for Everyday Use

For most individuals, 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 every day.
