Symbol of rechargeable hearing aid battery charging.

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

Those questions are understandable, as is the accompanying anxiety. A hearing aid is often a vital part of one’s day-to-day life, as necessary for a quick visit to the grocery store as they are for the enjoyment of a movie or television show. It’s important that a piece of technology functions properly and reliably, especially when it affects so many facets of life.

What Type of Battery do I Have?

By default, most modern-day hearing aids have rechargeable batteries, 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 distinguished 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.

How to Care For Your Rechargeable Hearing Aid

For the most part, rechargeable hearing aids do work, and they work well. The reliability of these devices has enhanced significantly in the last few years, as battery technologies have improved. In order to increase reliability, however, there are some maintenance steps users can take as they would with any other electronic equipment.

  • Keep Your Hearing Aids Dry and Clean: No matter how often you use or do not use your hearing aids, they have abundant occasion to collect dust, debris, and moisture. Any combination of these three things can diminish the capacity of your battery and can hinder charging in sufficient quantities. That’s why it’s important 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. Most hearing aid users are advised to be aware of these wires; the connection that enables the device to charge can be broken if you pull on or hold it by the wires.
  • The Charging Station is Where Your Hearing Aids Should be Stored: If your hearing aids have rechargeable batteries, you can extend your device’s battery life by making sure 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 completely drained.As a matter of fact, you can actually increase the battery life 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 put the charging station on a table beside their bed.

How to Change a Rechargeable Battery

If you have lithium-ion batteries, they should last as long as your device does. Consequently, you shouldn’t need to worry about replacing those batteries. Simply keep recharging your hearing aids as long as necessary.

However, you will need to occasionally change the batteries if you have a hearing aid that utilizes silver-zinc batteries. The lifespan of your battery can be improved by replacing them in the correct way. Because of this, hearing professionals recommend the following:

  • Let the batteries sit out at room temperature for at least five minutes before taking off any tabs that might be attached.
  • Make certain you have a dry, room temperature place to store your batteries.
  • Before replacing batteries, make sure you wash your hands.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Don’t eliminate any packaging or plastic tabs until you’re ready to use batteries.

Non-Use For Long Periods

If you are planning not to use your hearing aids for long amounts of time, leaving them on the charger might no longer be the best way to store your devices. If, for example, you know that you will not be using your hearing aids for a few weeks or months, you can simply remove the charger and store your hearing aids in a dry and cool spot.

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

Rechargeable for Everyday Use

For most individuals, and for everyday use, charging your hearing aids once a day should be adequate for all of your requirements. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours every day.
