Symbol of rechargeable hearing aid battery charging.

Worrying about losing battery power is something you shouldn’t have to do with rechargeable hearing aids, but when you rely on this technology, it may make you slightly concerned. Do rechargeable hearing aids work, and do they work as well as advertised?

The stress is reasonable and so are the question you might have. A hearing aid is often as important for the enjoyment of a tv show or a movie as it is for a trip to the grocery store or any other part of day to day life. It’s important that a piece of technology works properly and reliably, especially when it impacts so many aspects of life.

What Kind of Battery do I Have?

By default, most modern hearing aids come with rechargeable batteries, so it’s likely if you bought your hearing aids recently, it has one of two kinds of batteries. Silver-zinc batteries, which can usually be distinguished 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 last throughout the life-cycle of the hearing device and, due to this, those devices will not have that telltale battery door.

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 improved in the last few years, the reliability of these devices has increased significantly. As with any other electronic device, however, there are some easy maintenance steps that users can take to improve the reliability of their rechargeable hearing aids.

  • Keep Your Hearing Aids on The Charging Station: If your hearing aids have rechargeable batteries, you can extend the battery life of your device by ensuring that you consistently store your hearing aids on their charging station. Charging a battery that is not fully drained does not diminish long-term battery life. As a matter of fact, making sure that your hearing aids are charging when not in use can actually boost your long-term battery life. A convenient reminder, for most people, to charge their device when not in use, is to put the charging station on a table near their bed.
  • Be Careful of Wires: Either the charging station or the hearing aid itself will have some kind of wire element on most hearing aids. Most hearing aid users are advised to be mindful 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 Dry and Clean: Your hearing aids will collect debris, dust, and moisture regardless of how often you use them. Your hearing aid may not completely 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 a must to keep your device clean.

How to Replace a Rechargeable Battery

If you have lithium-ion batteries, they will probably last as long as your device does. Because of this, you shouldn’t need to worry about changing those batteries. Simply keep recharging your hearing aids as long as necessary.

Hearing aids that depend on silver-zinc batteries, however, might need fresh batteries periodically. Replacing batteries in the right 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:

  • Don’t eliminate any packaging or plastic tabs until you’re ready to use batteries.
  • Make sure you have a dry, room temperature spot to store your batteries.
  • Confirm that your battery compartment is clean and free of moisture.
  • Let the batteries sit out at room temperature for at least five minutes before removing any tabs that may be attached.
  • Ensure you wash your hands before changing your hearing aid batteries.

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. Just unplug your hearing aid and store it in a dry cool place if, for instance, you know you won’t be using them for a few weeks or a month.

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

Keep it Charged Every Day

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