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 depend on this technology, it might make you slightly nervous. Do rechargeable hearing aids work, and do they work as well as advertised?

Those questions are reasonable, as is the accompanying stress. A hearing aid can be a necessary element of one’s everyday 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 essential that a piece of technology functions correctly and dependably, especially when it affects so many aspects of life.

What Kind of Battery do I Have?

By default, most contemporary hearing aids come with 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 identified by a battery door on the device, are rechargeable, but every now and then 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. The reliability of these devices has increased significantly in the last few years, as battery technologies have advanced. In order to increase reliability, however, there are some maintenance measures users can take as they would with any other electronic equipment.

  • 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. Most hearing aid users are advised to be aware of these wires; do not pull or hold your device by these wires as this will damage the connections that enable your hearing aid to charge.
  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Any combination of these three things can diminish the capacity of your battery and can interfere with charging as much as it needs. When connecting your hearing aid to your charging station, as with any other time, it’s a must to keep your device clean.
  • 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 regularly store your hearing aids on their charging station. Charging a battery that is not fully drained does not shorten long-term battery life. As a matter of fact, you can actually enhance the life of the battery by making sure your hearing aids are charging when not in use. For many people, placing their charging station beside their bed is a simple reminder to charge the devices when it’s not in use.

How to Replace a Rechargeable Battery

Lithium-ion batteries will normally last the as long as your device does. So replacing those batteries won’t be something you ever have to be concerned about. Your hearing aids can then be simply charged as long as needed.

However, you will need to periodically change the batteries if you have a hearing aid that utilizes silver-zinc batteries. Switching batteries in the right way can help increase the longevity of your hearing aids. As such, the majority of people who use these hearing aids are counseled to:

  • Five minutes before taking off any tabs that might be attached let the batteries sit at room temperature.
  • Don’t get rid of any plastic tabs or packaging until you’re ready to use batteries.
  • Store batteries in a room temperature place that is also sure to be dry.
  • Ensure you wash your hands before replacing your hearing aid batteries.
  • Ensure that your battery compartment is clean and free of moisture.

Long Periods of Non-Use

If you are planning not to use your hearing aids for long amounts of time, leaving them on the charger may 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 instance, 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 think about leaving the battery door open so that you can stop moisture from corroding your batteries.

Keep it Charged Every Day

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