Rechargeable hearing aids are manufactured so that you’ll have to worry less about losing battery power, but the technology might also make you a little concerned when you depend on your devices to hear. Do rechargeable hearing aids work, and do they work as well as advertised?

Those questions are reasonable, as is the accompanying stress. A hearing aid is often a necessary 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. It’s essential that a piece of technology works properly and reliably, especially when it impacts so many facets of life.

How Do I Know What Kind of Battery I Have?

By default, most modern-day hearing aids have 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 the batteries might need to be replaced every so often. A Lithium-ion battery, however, will not have a battery door because the batteries will last as long as the hearing aid does.

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 increased significantly in the last few years, as battery technologies have improved. In order to improve reliability, however, there are some maintenance measures users can take as they would with any other electronic device.

  • Be Careful of Wires: Most hearing aids will contain a wire element of some kind, either on the hearing aids themselves or on the charging station. Being mindful of these wires is important for hearing aid users; do not pull or hold your device by these wires as this will damage the connections that allow your hearing aid to charge.
  • 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 might not completely 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 essential to keep your device clean.
  • The Charging Station is Where Your Hearing Aids Should be Stored: If you consistently store your rechargeable hearing aids on their recharging station you can increase the life of your battery. The long term battery life is not shortened by charging a battery that is not totally drained.In fact, you can actually improve the battery life by making sure your hearing aids are charging when not in use. For lots of people, placing their charging station beside their bed is a convenient reminder to charge the devices when it’s not being used.

How to Change a Rechargeable Battery

Lithium-ion batteries will normally last the as long as your device does. As a result, you should not need to worry about changing those batteries. Your hearing aids can then be simply charged as long as needed.

Hearing aids that depend on silver-zinc batteries, however, may require new batteries occasionally. The lifespan of your battery can be increased by changing them in the correct way. Because of this, hearing professionals recommend the following:

  • Before changing batteries, be sure you wash your hands.
  • 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 might be attached.
  • Keep batteries in a room temperature spot that is also sure to be dry.
  • Clean and free of moisture is the state that your battery compartment should be kept in.

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. Simply disconnect your hearing aid and store it in a dry cool spot if, for example, you know you won’t be using them for several weeks or a month.

Consider leaving the battery door open so you can prevent moisture from corroding the batteries if you use 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 needs. To get 24 hours worth of battery life with a lithium-ion battery will usually only require 3-4 hours every day.
