Why does my hearing aid battery suddenly last a shorter time?

Answer

In most of the cases, the reasons for a short running time are not necessarily production faults, but rather:

  • Environmental influences (e.g. humidity, temperature).
  • Personal hearing habits have changed (longer period of use per day, higher noise level, new features of the hearing aid are being used).
  • The hearing aid was in use longer than usual (e.g. night at the theatre).
  • The hearing aid is new, or the type or brand of the hearing aid has changed.
  • The new hearing aid has additional features that require more energy.

Improper handling can also reduce the running time of the hearing aid battery, e.g.:

  • The battery tab is removed and the activation period as too short. It has to be 2 minutes or more before it is inserted into the hearing aid.
  • The hearing aid is not switched off overnight or after a long period of non-use.
  • The battery loses capacity due to a short circuit when mishandled (e.g. through contact with metal objects).
  • The battery is stored in a warm environment (e.g. in a parked car in the sun).
