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.

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.
