Rechargeable hearing aids are designed so that you’ll need to worry less about running low on batteries, but the technology might 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 advertised?

The worry is understandable and so are the question you may have. A hearing aid can be a necessary element of one’s day-to-day life, as necessary for a simple visit to the grocery store as they are for the enjoyment of a television show or movie. When a piece of technology affects so many aspects of your life, it’s important that it functions properly and dependably.

What Type of Battery do I Have?

Most modern hearing aids are equipped with rechargeable batteries by default, 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 can normally be identified by a battery door on the device, are rechargeable, but every now and then they have 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 improved. In order to improve dependability, however, there are a few maintenance steps users can take as they would with any other electronic device.

  • 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. Most hearing aid users are counseled to be mindful of these wires; do not pull or hold your device by these wires as this can damage the connections that allow your hearing aid to charge.
  • Keep Your Hearing Aids Clean and Dry: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Your hearing aid may not thoroughly charge if it is exposed to any of these three things. When connecting your hearing aid to your charging station, as with any other time, it’s crucial to keep your device clean.
  • Keep Your Hearing Aids on The Charging Station: If your hearing aids have rechargeable batteries, you can extend the battery life of your device by ensuring that you consistently store your hearing aids on their charging station. Charging a battery that is not completely drained does not diminish long-term battery life. In fact, you can actually increase the battery life by making sure your hearing aids are charging while not in use. For lots of people, putting their charging station beside their bed is a convenient reminder to charge the devices when it’s not in use.

How to Change a Rechargeable Battery

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

However, you will need to periodically change the batteries if you have a hearing aid that utilizes silver-zinc batteries. The longevity of your battery can be improved by changing them in the right way. As a result, most people who use these hearing aids are counseled to:

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

Non-Use For Long Periods

Leaving your hearing aids on the charger for long periods of time is no longer the way to store your hearing aids. Simply disconnect your hearing aid and store it in a cool dry spot if, for instance, you know you won’t be using 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 in order to prevent moisture from corroding your batteries.

Keep it Charged Every Day

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