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 rely on this technology, it may 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 can be a vital part of one’s day-to-day life, as necessary for a simple trip to the grocery store as they are for the enjoyment of a television show or movie. It’s essential that a piece of technology functions correctly and reliably, especially when it impacts so many facets of life.

What Kind of Battery do I Have?

Most contemporary 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 can usually be distinguished by a battery door on the device, are rechargeable, but the batteries may have to be replaced every so often. 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 enhanced dramatically in the last several years, as battery technologies have improved. In order to increase reliability, however, there are a few maintenance measures users can take as they would with any other electronic device.

  • The Charging Station is Where Your Hearing Aids Should be Stored: If your hearing aids have rechargeable batteries, you can increase your device’s battery life by ensuring that you regularly store your hearing aids on their charging station. Charging a battery that is not totally drained does not reduce the long term life of your battery. In fact, you can actually increase the battery life by making certain your hearing aids are charging when not in use. For many people, placing their charging station next to their bed is a simple reminder to charge the devices when not being used.
  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect debris, dust, and moisture regardless of how often you use them. Your hearing aid may not thoroughly charge if it is exposed to any of these three elements. When connecting your hearing aid to your charging station, as with any other time, it’s important to keep your device clean.
  • Be Careful of Wires: Either the charging station or the hearing aid itself will have some type of wire element on most hearing aids. Being mindful of these wires is important for hearing aid users; the connection that enables the device to charge can be damaged if you pull on or hold it by the wires.

How to Change 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 worry about. Simply continue recharging your hearing aids as long as necessary.

However, you will want to periodically replace the batteries if you have a hearing aid that uses silver-zinc batteries. The longevity of your battery can be improved by changing them in the right way. Because of this, hearing professionals recommend the following:

  • Five minutes before taking off any tabs that may be attached let the batteries sit at room temperature.
  • Make sure you have a dry, room temperature spot to keep your batteries.
  • Ensure that your battery compartment is free of moisture and clean.
  • Be sure you wash your hands before replacing your hearing aid batteries.
  • Don’t remove any packaging or plastic tabs until you’re ready to use batteries.

Non-Use For Long Periods

If you are planning not to use your hearing aids for long amounts of time, leaving them on the charger might no longer be the best way to store your devices. Simply unplug your hearing aid and put it in a dry cool spot if, for example, you know you won’t be wearing them for several weeks or a month.

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

Rechargeable for Everyday Use

For most individuals, and for day to day use, charging your hearing aids once a day should be adequate for all of your requirements. A lithium-ion battery, as an example, will usually require just 3-4 hours to charge enough battery power for a 24 hour period.
