Stressing about losing battery power is something you shouldn’t have to do with rechargeable hearing aids, but when you rely on this technology, it might make you a little concerned. Do rechargeable hearing aids work as well as marketed or do they even work at all?

The anxiety is reasonable and so are the question you might have. A hearing aid is often as necessary for the enjoyment of a tv show or a movie as it is for a trip to the grocery store or any other part of daily life. When a piece of technology impacts so many aspects of your life, it’s essential that it work correctly and reliably.

How Do I Know What Kind of Battery I Have?

Most modern-day hearing aids have 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 have a battery door on the back of the device, are rechargeable, but the batteries might have to be replaced every now and then. A Lithium-ion battery, however, will last for the duration of 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 dramatically in the last several years, as battery technologies have improved. And, like any other electronic device, however, there are some easy maintenance procedures that users can practice to improve the reliability of their rechargeable hearing aids.

  • 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 may not thoroughly 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.
  • Be Careful of Wires: Most hearing aids will have a wire element of some kind, either on the charging station or on the hearing aids themselves. Most hearing aid users are advised to be careful of these wires; do not pull or hold your device by these wires as this can damage the connections that allow your hearing aid to charge.
  • Keep Your Hearing Aids on The Charging Station: If you consistently store your rechargeable hearing aids on their recharging station you can extend the life of your battery. The long term battery life is not shortened by charging a battery that is not fully drained.As a matter of fact, ensuring that your hearing aids are charging when you’re not using them can actually maximize your long-term battery life. For lots of people, placing their charging station next to their bed is a simple reminder to charge the devices when not in use.

How to Change a Rechargeable Battery

If you have lithium-ion batteries, they should last as long as your device does. Consequently, you should not need 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 utilizes silver-zinc batteries. The longevity of your battery can be increased by changing them in the correct way. Because of this, hearing professionals recommend the following:

  • Make sure you wash your hands before changing your hearing aid batteries.
  • Make sure you have a dry, room temperature spot to store your batteries.
  • Don’t remove any plastic tabs or packaging 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.

Non-Use For Long Periods

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

Consider leaving the battery door open so you can prevent moisture from corroding the batteries if you have silver-zinc batteries.

Keep it Charged Every Day

All your basic needs 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.
