Symbol of rechargeable hearing aid battery charging.

Stressing about losing battery power is something you shouldn’t have to do with rechargeable hearing aids, but when you rely on this technology, it might make you a little nervous. Do rechargeable hearing aids work as well as marketed or do they even work at all?

Those questions are reasonable, as is the accompanying anxiety. A hearing aid is often a necessary element of one’s day-to-day life, as necessary for a simple trip to the grocery store as they are for the enjoyment of a movie or television show. When a piece of technology affects so many aspects of your life, it’s essential that it functions properly and reliably.

What Type of Battery do I Have?

By default, most contemporary hearing aids have rechargeable batteries, so it’s likely if you bought your hearing aids recently, it has one of two types of batteries. Silver-zinc batteries, which can normally 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 last for the duration of the life-cycle of the hearing device and, as such, those devices will not have that telltale battery door.

Rechargeable Hearing Aids Need Special Care

For the most part, rechargeable hearing aids do work, and they work well. As battery technology has improved in the last several years, the dependability of these devices has increased dramatically. As it is with any other electronic device, however, there are a few easy maintenance steps that users can practice to improve the dependability of their rechargeable hearing aids.

  • Put Your Hearing Aids on The Charging Station: If you regularly store your rechargeable hearing aids on their recharging station you can extend the life of your battery. The long term battery life is not diminished by charging a battery that is not totally drained.Actually, you can actually increase the battery life by making certain your hearing aids are charging while not in use. A simple reminder, for most people, to charge their device when it’s not used, is to put the charging station on a table beside their bed.
  • Keep Your Hearing Aids Clean and Dry: No matter how often you use or do not use your hearing aids, they have plenty of occasion to accumulate moisture, debris, and dust. Any combination of these three things can undercut the capacity of your battery and can obstruct charging in sufficient quantities. When connecting your hearing aid to your charging station, as with any other time, it’s a must to keep your device clean.
  • Be Mindful of Wires: Most hearing aids will have a wire element of some kind, either on the hearing aids themselves or on the charging station. Most hearing aid users are counseled to be mindful of these wires; do not pull or hold your device by these wires as this will damage the connections that allow your hearing aid to charge.

How to Change a Rechargeable Battery

Lithium-ion batteries should last the as long as your device does. So replacing those batteries won’t be something you ever have to be concerned about. Simply keep recharging your hearing aids as long as necessary.

However, you will want to occasionally change the batteries if you have a hearing aid that uses silver-zinc batteries. Replacing batteries in the right way can help increase the lifespan of your hearing aids. As such, most people who use these hearing aids are counseled to:

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

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 manner to store your devices. If, for example, you know that you will not be wearing your hearing aids for several weeks or months, you can just disconnect the charger and store your hearing aids in a dry and cool spot.

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