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 might make you slightly concerned. Do rechargeable hearing aids work as well as advertised or do they even work at all?

The worry is reasonable and so are the question you may have. A hearing aid can be a vital element 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 movie or television show. It’s essential that a piece of technology functions properly 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 kinds of batteries. Silver-zinc batteries, which have a battery door on the back, are rechargeable, but every so often they have to be replaced. A Lithium-ion battery, however, will last for the duration of the life-cycle of the hearing device and, as such, 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. As battery technology has advanced in the last several years, the reliability of these devices has increased substantially. As with any other electronic device, however, there are various easy maintenance procedures that users can take to improve the dependability of their rechargeable hearing aids.

  • Keep Your Hearing Aids Dry and Clean: No matter how often you use or do not use your hearing aids, they have abundant opportunity to collect dust, debris, and moisture. Your hearing aid may not completely charge if it is exposed to any of these three elements. 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 shortened by charging a battery that is not fully drained.Actually, you can actually increase the battery life by making certain your hearing aids are charging when not in use. For lots of people, placing their charging station beside their bed is a convenient reminder to charge the devices when not in use.
  • Be Mindful of Wires: Most hearing aids will contain a wire element of some kind, either on the hearing aids themselves or on the charging station. Most hearing aid users are advised to be careful of these wires; the connection that allows the device to charge can be broken if you pull on or hold it by the wires.

How to Replace a Rechargeable Battery

If you have lithium-ion batteries, they should last as long as your device does. So replacing those batteries won’t be something you ever have to be concerned about. Simply continue recharging your hearing aids as long as needed.

However, you will need to occasionally change the batteries if you have a hearing aid that utilizes silver-zinc batteries. Changing batteries in the right way can help improve the lifespan of your hearing aids. Because of this, hearing professionals suggest the following:

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

Non-Use For Long Periods

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

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

Keep it Charged Every Day

All your general requirements should be met if you charge your hearing aids once a day. A lithium-ion battery, as an example, will typically require only 3-4 hours to charge adequate battery power for a 24 hour period.
