Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are manufactured so that you’ll need to stress less about losing battery power, but the technology may also make you a little nervous when you depend on your devices to hear. Do rechargeable hearing aids work, and do they work as well as marketed?

Those questions are reasonable, as is the accompanying anxiety. 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 supermarket or any other part of everyday life. It’s important that a piece of technology functions properly and dependably, especially when it affects so many aspects of life.

What Kind of Battery do I Have?

Most modern-day hearing aids are equipped with rechargeable batteries by default, so if you got your hearing aids recently it’s likely that your hearing aids will have one of two battery types. Silver-zinc batteries, which can usually be identified by a battery door on the device, are rechargeable, but every so often they need to be replaced. 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 significantly in the last few years, as battery technologies have advanced. 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.

  • 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 aware of these wires is crucial for hearing aid users; the connection that enables the device to charge can be broken if you pull on or hold it by the wires.
  • 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 might not thoroughly charge if it is subjected to any of these three elements. That’s why it’s important to keep your hearing aids clean and dry especially when connecting your hearing aid to its charging station.
  • The Charging Station is Where Your Hearing Aids Should be Kept: If your hearing aids have rechargeable batteries, you can increase the battery life of your device by making sure that you regularly store your hearing aids on their charging station. Charging a battery that is not completely drained does not diminish long-term battery life. Actually, you can actually enhance the life of the battery by making sure your hearing aids are charging when not in use. A simple reminder, for most people, to charge their device when it’s not in use, is to set the charging station on a table beside their bed.

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. Simply keep recharging your hearing aids as long as necessary.

However, you will need to periodically replace the batteries if you have a hearing aid that uses silver-zinc batteries. Replacing batteries in the correct way can help improve the lifespan of your hearing aids. Because of this, hearing experts suggest the following:

  • Store batteries in a room temperature place that is also sure to be dry.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Before changing batteries, make sure you wash your hands.
  • Until you’re ready to use the batteries, don’t remove the plastic tabs or packaging.
  • Let the batteries sit out at room temperature for at least five minutes before removing any tabs that might be attached.

Long Periods of Non-Use

Leaving your hearing aids on the charger for extended periods of time is no longer the way to store your hearing aids. If, for example, you know that you will not be using your hearing aids for a few weeks or months, you can just disconnect the charger and store your hearing aids in a cool and dry spot.

If your hearing aids use silver-zinc batteries, you might also consider leaving the battery door open in order to prevent moisture from corroding your batteries.

Rechargeable for Everyday Use

All your general needs should be satisfied if you charge your hearing aids once per day. A lithium-ion battery, as an example, will usually require just 3-4 hours to charge sufficient battery power for a 24 hour period.
