How long does the Core One battery last?

The Core One hearing aids have a rated battery life of approximately 13 hours per charge.

Signs your battery is low

• The charging case indicator light will begin flashing when the case battery is nearly empty.
• You will hear a Beep-Beep-Beep tone from the hearing aids when the case battery is almost run out.

What to do when the battery is low

1. Place the hearing aids back in the charging case as soon as possible.
2. Connect the charging case to power using the USB cable.
3. Wait until the charging case indicator shows a solid white light, which means the hearing aids are fully charged.

Tips for better battery life

• Store the hearing aids in the charging case when not in use to keep them charged.
• Charge the case before the battery is fully depleted — aim to charge it at least every 28 days even when not in regular use.
• Keep the charging contacts on both the hearing aids and case clean and dry.
• Avoid exposing the devices to extreme temperatures or high humidity, which can degrade battery performance.
