How many days a hearing aid battery lasts ?

A hearing aid battery life depends on following factors

  • energy and power the hearing aid needs
  • number of hours the aid used
  • type and technology of hearing aid
  • severity of hearing loss
  • additional features in the hearing aid
  • size of the battery
  • humidity and temperature

Some of the new digital hearing aids consume very less battery power and hence give longer battery life. Therefore, some batteries may last for weeks while others can last only days.
