Do Rechargeable Hearing Aid Batteries Actually Work?

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

Those questions are reasonable, as is the accompanying anxiousness. 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 everyday life. When a piece of technology affects so many facets of your life, it’s important that it functions correctly and dependably.

How Do I Know What Kind of Battery I Have?

Most modern hearing aids have rechargeable batteries by default, so if you purchased 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.

How to Care For Your Rechargeable Hearing Aid

For the most part, rechargeable hearing aids do work, and they work well. As battery technology has advanced in the last few years, the dependability of these devices has increased significantly. In order to increase dependability, however, there are some maintenance measures users can take as they would with any other electronic technology.

  • Be Mindful 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 mindful of these wires is important for hearing aid users; do not pull or hold your device by these wires as this will damage the connections that allow your hearing aid to charge.
  • The Charging Station is Where Your Hearing Aids Should be Kept: If you consistently store your rechargeable hearing aids on their recharging station you can extend the life of your battery. Charging a battery that is not totally drained does not diminish long-term battery life. In fact, you can actually increase the life of the battery 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 convenient reminder to charge the devices when it’s not in use.
  • 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 may not fully charge if it is exposed to any of these three things. That’s why it’s important to keep your hearing aids dry and clean particularly when connecting your hearing aid to its charging station.

How to Replace a Rechargeable Battery

If you have lithium-ion batteries, they will probably last as long as your device does. So changing those batteries won’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 occasionally replace the batteries if you have a hearing aid that uses silver-zinc batteries. The longevity of your battery can be improved by replacing them in the right way. As such, most people who use these hearing aids are counseled to:

  • Store batteries in a room temperature spot that is also certain to be dry.
  • Don’t eliminate any packaging or plastic tabs until you’re ready to use batteries.
  • Be sure you wash your hands before replacing your hearing aid batteries.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Five minutes before taking off any tabs that might be attached let the batteries sit at room temperature.

Long Periods of Non-Use

If you are planning not to use your hearing aids for long periods of time, leaving them on the charger might no longer be the best way to store your devices. Simply disconnect your hearing aid and store it in a dry cool spot if, for example, you know you won’t be wearing them for a few weeks or a month.

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

Rechargeable for Everyday Use

For most people, and for day to day use, charging your hearing aids once per day should be enough for all of your needs. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours per day.
