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 as well as advertised or do they even work at all?

Those questions are understandable, as is the accompanying anxiousness. A hearing aid can be a vital part of one’s day-to-day life, as necessary for a quick visit to the grocery store as they are for the enjoyment of a movie or television show. When a piece of technology affects so many facets of your life, it’s crucial that it functions properly and dependably.

What Type of Battery do I Have?

Most contemporary hearing aids have rechargeable batteries by default, 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 have a battery door on the back of 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, 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. As battery technology has improved in the last few years, the reliability of these devices has increased significantly. And, like any other electronic device, however, there are various easy maintenance procedures that users can take to increase the reliability of their rechargeable hearing aids.

  • Keep Your Hearing Aids Dry and Clean: Your hearing aids will collect moisture, dust, and debris regardless of how often you use them. Your hearing aid may not completely charge if it is exposed to any of these three elements. 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: Either the charging station or the hearing aid itself will have some type of wire element on most hearing aids. Being mindful of these wires is essential for hearing aid users; the connection that enables the device to charge can be broken if you pull on or hold it by the wires.
  • Put Your Hearing Aids on The Charging Station: If your hearing aids have rechargeable batteries, you can extend the battery life of your device by making sure that you regularly store your hearing aids on their charging station. Charging a battery that is not completely drained does not diminish the long term life of your battery. As a matter of fact, making sure that your hearing aids are charging when not in use can actually improve your long-term battery life. For lots of people, placing their charging station next to their bed is a simple reminder to charge the devices when it’s not in use.

How to Change a Rechargeable Battery

If you have lithium-ion batteries, they will probably last as long as your device does. So changing those batteries won’t be something you ever have to worry about. Simply keep recharging your hearing aids as long as needed.

However, you will need to occasionally change the batteries if you have a hearing aid that utilizes silver-zinc batteries. The longevity of your battery can be increased by changing them in the correct way. 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.
  • Make sure you wash your hands before replacing your hearing aid batteries.
  • Clean and free of moisture is the state that your battery compartment should be kept in.
  • Store 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.

Long Periods of Non-Use

Leaving your hearing aids on the charger for extended periods of time is no longer the best way to store your hearing aids. Just disconnect your hearing aid and store it in a dry cool place if, for instance, you know you won’t be wearing them for several weeks or a month.

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

Rechargeable for Everyday Use

For most individuals, and for day to day use, charging your hearing aids once per day should be sufficient for all of your requirements. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours every day.
