Symbol of rechargeable hearing aid battery charging.

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 nervous when you depend on your devices to hear. Do rechargeable hearing aids work, and do they work as well as advertised?

The anxiety is reasonable and so are the question you may have. A hearing aid is often a vital part of one’s day-to-day life, as necessary for a quick trip to the grocery store as they are for the enjoyment of a television show or movie. It’s essential that a piece of technology works properly and reliably, especially when it affects so many facets of life.

How Do I Know What Kind of Battery I Have?

By default, most contemporary hearing aids come with rechargeable batteries, 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 normally be distinguished by a battery door on the device, are rechargeable, but the batteries might need to be changed every so often. A Lithium-ion battery, however, will last throughout the life-cycle of the hearing device and, as such, those devices will not have that distinguishing battery door.

How to Care For Your Rechargeable Hearing Aid

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

  • Keep Your Hearing Aids on The Charging Station: 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, ensuring that your hearing aids are charging when not in use can actually boost your long-term battery life. 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.
  • Be Careful of Wires: Either the hearing aid itself or the charging station will have some type of wire element on most hearing aids. Most hearing aid users are advised to be aware of these wires; the connection that allows the device to charge can be damaged if you pull on or hold it by the wires.
  • Keep Your Hearing Aids Clean and Dry: No matter how often you use or do not use your hearing aids, they have plenty of opportunity to collect dust, debris, and moisture. Your hearing aid may not thoroughly charge if it is subjected to any of these three things. When connecting your hearing aid to your charging station, as with any other time, it’s essential to keep your device clean.

How to Replace a Rechargeable Battery

Lithium-ion batteries should last the lifespan of your device. As a result, you shouldn’t need to worry about replacing those batteries. Your hearing aids can then be simply charged as long as necessary.

Hearing aids that depend on silver-zinc batteries, however, may need new batteries once in a while. Changing batteries in the right way can help increase the longevity of your hearing aids. As such, most people who use these hearing aids are counseled to:

  • Make certain you have a dry, room temperature spot to store your batteries.
  • Until you’re ready to use the batteries, don’t remove the plastic tabs or packaging.
  • Let the batteries sit out at room temperature for at least five minutes before taking off any tabs that may be attached.
  • Before changing batteries, be sure you wash your hands.
  • Ensure that your battery compartment is free of moisture and clean.

Long Periods of Non-Use

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

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

Keep it Charged Every Day

For most people, and for everyday use, charging your hearing aids once per day should be sufficient for all of your requirements. A lithium-ion battery, as an example, will usually require just 3-4 hours to charge sufficient battery power for a 24 hour period.
