Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are designed so that you’ll have to worry less about losing battery power, but the technology may also make you slightly nervous when you rely on your devices to hear. Do rechargeable hearing aids work as well as advertised or do they even work at all?

Those questions are understandable, as is the accompanying stress. A hearing aid is often as important for the enjoyment of a television show or a movie as it is for a trip to the grocery store or any other part of day to day life. When a piece of technology affects so many aspects of your life, it’s important that it work properly and reliably.

What Type of Battery do I Have?

By default, most contemporary hearing aids come with rechargeable batteries, so if you bought 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 of the device, are rechargeable, but the batteries might need to be changed 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 reliability of these devices has increased dramatically in the last several years, as battery technologies have advanced. As with any other electronic device, however, there are some easy maintenance steps that users can take to increase the reliability of their rechargeable hearing aids.

  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect debris, dust, and moisture regardless of how often you use them. Any combination of these three elements can undercut the efficiency of your battery and can obstruct charging as much as it needs. That’s why it’s essential to keep your hearing aids clean and dry particularly when connecting your hearing aid to its charging station.
  • The Charging Station is Where Your Hearing Aids Should be Stored: If you regularly store your rechargeable hearing aids on their recharging station you can extend the life of your battery. The long term battery life is not diminished by charging a battery that is not fully drained.Actually, you can actually enhance the battery life by making certain your hearing aids are charging while not in use. For lots of people, setting their charging station beside their bed is a convenient reminder to charge the devices when not being used.
  • Be Careful of Wires: Most hearing aids will have a wire element of some kind, either on the hearing aids themselves or on the charging station. Being mindful of these wires is important for hearing aid users; do not pull or hold your device by these wires as this can damage the connections that enable your hearing aid to charge.

How to Replace a Rechargeable Battery

If you have lithium-ion batteries, they should last as long as your device does. So changing those batteries shouldn’t be something you ever have to be concerned about. Your hearing aids can then be simply charged as long as needed.

However, you will want to occasionally replace the batteries if you have a hearing aid that uses silver-zinc batteries. Changing batteries in the correct way can help improve the lifespan of your hearing aids. As a result, most people who use these hearing aids are counseled to:

  • 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 certain you have a dry, room temperature place to keep your batteries.
  • Before replacing batteries, be sure you wash your hands.
  • Don’t eliminate any plastic tabs or packaging until you’re ready to use batteries.

Non-Use For Long Periods

Keeping your hearing aids on the charger for extended periods of time is no longer the best way to store your hearing aids. If, for example, you know that you won’t be wearing your hearing aids for a few weeks or months, you can just unplug the charger and put your hearing aids in a dry and cool spot.

If your hearing aids utilize silver-zinc batteries, you might also think about leaving the battery door open so that you can stop moisture from corroding your batteries.

Keep it Charged Every Day

For most people, and for day to day use, charging your hearing aids once a 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 every day.
