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 depend on this technology, it may make you slightly 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 may have. A hearing aid is often 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.

How Do I Know What Kind of Battery I Have?

By default, most contemporary hearing aids have rechargeable batteries, so it’s likely if you bought your hearing aids recently, it has one of two kinds of batteries. Silver-zinc batteries, which can normally be distinguished by a battery door on the device, are rechargeable, but the batteries might have to be replaced every so often. 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 telltale 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 significantly in the last several years, as battery technologies have advanced. In order to increase dependability, however, there are some maintenance steps users can take as they would with any other electronic technology.

  • The Charging Station is Where Your Hearing Aids Should be Kept: 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 reduced by charging a battery that is not totally drained.As a matter of fact, ensuring that your hearing aids are charging when not in use can actually boost your long-term battery life. A simple reminder, for many people, to charge their device when it’s not in use, is to set the charging station on a table next to their bed.
  • Keep Your Hearing Aids Clean and Dry: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Any combination of these three things can diminish the capacity of your battery and can hinder 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.
  • Be Careful of Wires: Most hearing aids will contain a wire element of some kind, either on the hearing aids themselves or on the charging station. Being careful of these wires is crucial for hearing aid users; do not pull or hold your device by these wires as this will damage the connections that enable your hearing aid to charge.

How to Change a Rechargeable Battery

Lithium-ion batteries will normally last the as long as your device does. Because of this, you shouldn’t have to worry about replacing those batteries. Simply keep recharging your hearing aids as long as necessary.

Hearing aids that rely on silver-zinc batteries, however, might call for new batteries occasionally. The lifespan of your battery can be increased by changing them in the right way. As such, the majority of people who use these hearing aids are counseled to:

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

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 put it in a dry cool place if, for example, you know you won’t be using them for several weeks or a month.

Think about leaving the battery door open so you can stop moisture from corroding the batteries if you have silver-zinc batteries.

Rechargeable for Everyday Use

All your basic 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.

Do rechargeable hearing aids work? Not only do they work, but rechargeable hearing aids will probably become more and more common and reliable as the technology continues to improve. Contact your local hearing aid retailer to see all the different models
