Symbol of rechargeable hearing aid battery charging.

Rechargeable hearing aids are manufactured so that you’ll need to worry less about running low on batteries, but the technology might also make you slightly nervous when you rely on your devices to hear. Do rechargeable hearing aids work, and do they work as well as advertised?

Those questions are understandable, as is the accompanying anxiousness. A hearing aid is often as necessary 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 daily life. When a piece of technology affects so many facets of your life, it’s crucial that it work properly and dependably.

How Do I Know What Type of Battery I Have?

Most modern hearing aids have rechargeable batteries by default, so it’s likely if you bought your hearing aids recently, it has one of two kinds of batteries. Silver-zinc batteries, which have a battery door on the back of the device, are rechargeable, but the batteries might need to be changed every now and then. A Lithium-ion battery, however, will last throughout the life-cycle of the hearing device and, because of that, 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. The dependability of these devices has enhanced significantly in the last several years, as battery technologies have advanced. In order to improve dependability, however, there are some maintenance measures users can take as they would with any other electronic equipment.

  • 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 fully charge if it is subjected to any of these three elements. When connecting your hearing aid to your charging station, as with any other time, it’s crucial to keep your device clean.
  • Keep Your Hearing Aids on The Charging Station: If your hearing aids have rechargeable batteries, you can increase your device’s battery life by ensuring that you regularly store your hearing aids on their charging station. The long term battery life is not reduced by charging a battery that is not totally drained.Actually, you can actually enhance the battery life by making sure your hearing aids are charging when not in use. A convenient reminder, for most people, to charge their device when it’s not in use, is to put the charging station on a table beside their bed.
  • Be Mindful of Wires: Most hearing aids will contain a wire element of some kind, either on the charging station or on the hearing aids themselves. Most hearing aid users are advised to be aware of these wires; do not pull or hold your device by these wires as this can damage the connections that allow your hearing aid to charge.

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, might need fresh batteries now and then. Changing batteries in the correct way can help increase the longevity of your hearing aids. As such, most people who use these hearing aids are counseled to:

  • Five minutes before removing any tabs that might be attached let the batteries sit at room temperature.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Before replacing batteries, make sure you wash your hands.
  • Keep batteries in a room temperature spot that is also certain to be dry.
  • Until you’re ready to use the batteries, don’t remove the plastic tabs or packaging.

Non-Use For Long Periods

Leaving your hearing aids on the charger over extended periods of time is no longer the best way to store your hearing aids. If, for example, you know that you won’t be wearing your hearing aids for a few weeks or months, you can just unplug the charger and put your hearing aids in a dry and cool place.

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

Keep it Charged Every Day

All your basic requirements should be met 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 per day.
