Factors influencing the service life of the hearing aid battery

All of the different points make a person's hearing loss as unique as their fingerprint.

Individual hearing loss

If the hearing loss is more severe, increased sound amplification is necessary, which in turn results in increased power consumption battery has a shorter lifespan with greater hearing loss. That means the more that Hearing aid needs to work, the more electricity the hearing aid will need.

Individual use of your hearing aid

Your individual use of the hearing aid has a major impact on the life of your hearing aid batteries. As a result, the following aspects in particular must be taken into account:

  • How many hours per day is the hearing aid worn?
  • How many days a week is the hearing aid worn?
  • How often do you do remote digital adjustments / online remote adjustments?
  • How many hours do you watch TV through a TV hearing aid Streamer?
  • How long have you got your Hearing aid with bluetooth connected?

Differences in hearing aid types have different power consumption

You could say that the more advanced your hearing aid is, the more energy it needs. As a result, digital hearing aids have advanced features like wireless streaming, bluetooth connectivity and noise cancellation. These also require energy. The different functions also have different current requirements (mA), which affect the life of the hearing aid battery.

How do I optimally store the batteries?

There are various points that you should pay attention to in order to optimally store your hearing aid battery. The main points are the following:

  • You should store hearing aid batteries at room temperature
  • Avoid storing batteries in warm places, as heat will shorten their lifespan
  • Do not store batteries in the refrigerator
  • Store your hearing aid batteries in their turntable packaging, not loose in your bag, as various objects can short-circuit, leak, or burst the battery.
  • You should keep used batteries out of the reach of children

Your personal environment affects the life of the hearing aid battery

Your surroundings also have an impact on the life of your hearing aid battery. As a result, your hearing aid uses less battery than, for example, in a restaurant or at a concert. In a library, the hearing aid is exposed to a quiet environment and therefore only needs to process a very low level of background noise. During a visit to a restaurant, the hearing aid has to suppress background noise and emphasize speech frequencies. It's much more complex and requires more energy. The hearing aid battery also has a higher power consumption when the hearing aid is set to the maximum service life.

Various environmental influences and the hearing aid battery

Anyone who travels a lot might be surprised that the hearing aid battery is often empty faster than expected. You probably noticed that when you were on a beach or skiing holiday.

Low humidity

If the humidity is low, the active substances in the battery dry out faster, which can often lead to a shortened service life of the hearing aid battery. For example, if you spend long periods of time in a strongly heated room in winter, this can happen.

Low outside temperature

At a low outside temperature, the voltage of the hearing aid battery decreases. As a result, the lifespan of your hearing aid battery is shortened.

High humidity

When the humidity is high, a condensate film on the hearing aid battery can interfere with normal voltage discharge. This can significantly shorten the life of the hearing aid battery. In extreme cases, the hearing aid battery can even leak.

Altitude

At higher altitudes, such as mountainous regions or in an airplane, there is a lower oxygen content in the air. As a result, the battery voltage and discharge process may be reduced.

How long can my hearing aid batteries last?

Normally, hearing aid batteries can be used for up to four years from the date of manufacture.

How can I recycle/sustainably dispose of my old hearing aid batteries?

According to the European Battery Directive, all hearing aid batteries must be recycled. Often you will find certain facilities for disposing of hearing aid batteries and batteries in retail stores or in public buildings.

How often should I change my hearing aid batteries?

Once you've become familiar with your hearing aid and batteries, you'll see for yourself which system is best for you. So that you are always well prepared, it is best to always have spare batteries with you.
