Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are manufactured so that you’ll need to stress less about running low on batteries, but the technology may also make you slightly anxious when you rely on your devices to hear. Do rechargeable hearing aids work as well as marketed or do they even work at all?

Those questions are reasonable, as is the accompanying anxiety. 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 Kind of Battery I Have?

Most contemporary hearing aids have rechargeable batteries by default, 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 every so often they need to be replaced. A Lithium-ion battery, however, will last throughout the life-cycle of the hearing device and, as such, 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. The reliability of these devices has enhanced significantly in the last several years, as battery technologies have improved. As it is with any other electronic device, however, there are a few easy maintenance steps that users can take to increase the reliability of their rechargeable hearing aids.

  • 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. The long term battery life is not shortened by charging a battery that is not fully drained.In fact, you can actually improve 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 in use, is to set the charging station on a table beside their bed.
  • Be Mindful 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 counseled to be careful of these wires; the connection that allows the device to charge can be damaged if you pull on or hold it by the wires.
  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Any combination of these three elements can diminish the capacity of your battery and can hinder charging as much as it needs. When connecting your hearing aid to your charging station, as with any other time, it’s crucial to keep your device clean.

How to Replace a Rechargeable Battery

If you have lithium-ion batteries, they will probably last as long as your device does. Because of this, you should not have to worry about changing those batteries. Your hearing aids can then be simply charged as long as needed.

However, you will want to occasionally change the batteries if you have a hearing aid that uses silver-zinc batteries. Replacing batteries in the correct way can help improve the lifespan of your hearing aids. Because of this, hearing experts recommend the following:

  • Keep batteries in a room temperature place that is also certain to be dry.
  • Don’t get rid of any packaging or plastic tabs until you’re ready to use batteries.
  • Five minutes before removing any tabs that may be attached let the batteries sit at room temperature.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Make sure you wash your hands before replacing your hearing aid batteries.

Long Periods of Non-Use

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 wearing your hearing aids for a few weeks or months, you can just remove the charger and store your hearing aids in a cool and dry spot.

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

Rechargeable for Everyday Use

All your general requirements should be satisfied if you charge your hearing aids once per day. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours every day.
