Factors Affecting Battery Lifespan

  • Usage: Frequent use, especially with features like audio streaming or noise reduction, drains the battery faster.
  • Temperature: Extreme hot or cold temperatures can degrade battery performance. Store and charge your hearing aids at room temperature.

Tips for Maximizing Battery Life

Daily Charging Practices

  • Charge your hearing aids every night.
  • Avoid partial charges—fully charge your hearing aids to maintain battery efficiency.
  • Monitor the battery indicator on your hearing aids to plan your charging schedule.

Proper Storage of Hearing Aids

  • Use the provided case to protect your hearing aids from dust and damage.
  • Keep your hearing aids away from moisture—damp places can damage batteries and the device.
  • Store your hearing aids at room temperature—extreme temperatures can affect battery performance.

Regular Maintenance and Cleaning

  • Clean your hearing aids regularly to prevent earwax and debris from affecting battery contacts.
  • Check for damage—address any signs of wear and tear promptly to avoid further issues.
  • Use a dry cloth for cleaning—avoid water or cleaning solutions that could damage the device.
