Modern hearing aids are now becoming smaller and smaller with a much better and higher performance. For this, hearing aids need energy in the form of batteries to work without interruption.

 

Types of hearing aid batteries

There are two main types of hearing aid batteries, namely the rechargeable hearing aid battery and the standard disposable battery.

 

Chargeable hearing aid Rechargeable Hearing aid Batteries

The automation of rechargeable battery offers you an improved and more efficient power, smaller sizes, and environmental advantage.

When you visit a hearing aid centre in Malaysia, you will learn that many new hearing aids come with rechargeable batteries and these batteries are usually recharged at night when the user pulls out his/her hearing aids to sleep.

This rechargeable hearing aid gives the hearing aid user the flexibility to experience high-quality sound without the worry of carrying extra batteries. This rechargeable battery uses Li-ion batteries.

The Li-ion battery technology simply refers to the use of lithium ions which means that you can reuse the same battery by recharging the hearing aid with the required charger.

This rechargeable battery allows you to continue with your normal life with simple, safe and reliable charging.

Zinc-air disposable batteries are the most commonly used batteries for hearing aids because of their high energy density. The zinc-air technology provides extremely high voltage stability.

The zinc-air disposable battery can also be called button batteries. They are air-activated. Immediately the factory seal is peeled from the back of the battery, oxygen interacts with the zinc in the battery and makes it active.

For better efficiency of a zinc-air battery, you should wait for one minute after removing the factory seal to fully activate the battery before placing it in the hearing aid.

Replacing the factory seal does not deactivate the battery. Once the factory seal is removed, the battery remains active until the charges are used up. Zinc-air batteries can last up to 3 years if stored at room temperature and dry environment. A little trick for battery life conservation is to open the hearing aid battery doors when you remove the hearing aid device at night.

Most hearing aid centres allow you to drop off used hearing aid batteries for recycling purposes and to help keep them out of the waste stream.

cleaning hearing aid Maintenance of hearing aid batteries

  • Since hearing aid device batteries are air-activated, they should be left in their packaging until you need to use them.
  • Hearing aid device batteries should be stored at room temperature and not in the refrigerator.
  • The factory seal (color strip) should only be removed when you need to use them so as to protect the battery from oxidation.
  • Do not put the factory seal (color strip) back on to avoid damaging the battery.
  • At night, the hearing aid device should be turned off when not in use and the battery compartment should be left open. This will help conserve the battery’s power as the risk of condensation is reduced.
  • Hearing aid device batteries should not be stored in the pocket.

 

Takeaway

Hearing aids are very important for people with hearing issues. Understanding your hearing aid batteries can help prolong your battery lifespan and keep your hearing aids in tip-top condition.
