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 might make you slightly anxious. Do rechargeable hearing aids work, and do they work as well as marketed?

The worry is reasonable and so are the question you might have. 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 grocery store or any other part of daily life. When a piece of technology impacts so many areas of your life, it’s crucial that it work properly and reliably.

How Do I Know What Kind of Battery I Have?

Most modern-day hearing aids are equipped with 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 normally be distinguished 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. As battery technology has advanced in the last few years, the reliability of these devices has increased considerably. And, like any other electronic device, however, there are various easy maintenance steps that users can take to increase the dependability of their rechargeable hearing aids.

  • 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 elements can diminish the capacity of your battery and can obstruct charging in sufficient quantities. That’s why it’s essential to keep your hearing aids clean and dry specifically when connecting your hearing aid to its charging station.
  • Be Mindful of Wires: Either the charging station or the hearing aid itself will have some kind of wire element on most hearing aids. Most hearing aid users are counseled to be aware of these wires; do not pull or hold your device by these wires as this can damage the connections that enable your hearing aid to charge.
  • The Charging Station is Where Your Hearing Aids Should be Stored: 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. The long term battery life is not reduced by charging a battery that is not completely drained.In fact, you can actually enhance the battery life by making certain your hearing aids are charging while not in use. For many people, setting their charging station next to their bed is a convenient reminder to charge the devices when it’s not in use.

How to Change a Rechargeable Battery

Lithium-ion batteries should last the lifespan of your device. So changing those batteries shouldn’t be something you ever have to worry about. Your hearing aids can then be simply charged as long as necessary.

However, you will need to periodically replace the batteries if you have a hearing aid that utilizes silver-zinc batteries. The lifespan of your battery can be increased by replacing them in the right way. Because of this, hearing experts suggest the following:

  • Before changing batteries, make sure you wash your hands.
  • Five minutes before removing any tabs that may be attached let the batteries sit at room temperature.
  • Ensure that your battery compartment is clean and free of moisture.
  • Don’t eliminate any packaging or plastic tabs until you’re ready to use batteries.
  • Make sure you have a dry, room temperature spot to store your batteries.

Non-Use For Long Periods

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

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

Rechargeable for Everyday Use

All your general requirements should be satisfied if you charge your hearing aids once a day. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours per day.
