Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are manufactured so that you’ll have to stress less about running low on batteries, but the technology might also make you a little anxious when you depend on your devices to hear. Do rechargeable hearing aids work as well as advertised or do they even work at all?

The anxiety is understandable and so are the question you might have. A hearing aid can be a necessary part of one’s everyday life, as necessary for a simple trip to the grocery store as they are for the enjoyment of a movie or television show. When a piece of technology impacts so many areas of your life, it’s crucial that it work correctly and reliably.

What Type of Battery do I Have?

Most modern hearing aids have 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 usually be distinguished by a battery door on the device, are rechargeable, but the batteries may need to be changed every so often. A Lithium-ion battery, however, will last for the duration of the life-cycle of the hearing device and, because of that, 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 few years, the reliability of these devices has increased considerably. In order to increase dependability, however, there are some maintenance steps users can take as they would with any other electronic device.

  • Keep Your Hearing Aids Clean and Dry: Your hearing aids will collect debris, dust, and moisture regardless of how often you use them. Any combination of these three elements can undercut the capacity of your battery and can hinder charging in sufficient quantities. That’s why it’s important to keep your hearing aids dry and clean specifically 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 charging station or on the hearing aids themselves. Being careful of these wires is crucial for hearing aid users; 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 Kept: If your hearing aids have rechargeable batteries, you can extend your device’s battery life by ensuring that you consistently store your hearing aids on their charging station. The long term battery life is not shortened by charging a battery that is not fully 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, putting their charging station next to their bed is a simple 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. Because of this, you should not have to worry about changing those batteries. 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 uses silver-zinc batteries. Switching batteries in the correct way can help increase the lifespan of your hearing aids. As a result, the majority of people who use these hearing aids are counseled to:

  • Store batteries in a room temperature place that is also certain to be dry.
  • Ensure that your battery compartment is clean and free of moisture.
  • Until you’re ready to use the batteries, don’t remove the plastic tabs or packaging.
  • Before replacing batteries, make sure you wash your hands.
  • Five minutes before removing any tabs that might be attached let the batteries sit at room temperature.

Non-Use For Long Periods

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

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

Keep it Charged Every Day

For most individuals, and for day to day use, charging your hearing aids once a day should be adequate for all of your requirements. A lithium-ion battery, for example, will typically require just 3-4 hours to charge enough battery power for a 24 hour period.
