Frequently Asked Questions

Here are a few other questions you might encounter:

How long is the total battery lifetime?
Each battery is designed for more than 500 normal charging cycles. Rotating the batteries is important to help extended battery lifetime.

Can the charging system be plugged into any USB adapter?
It should be used with the included wall adapter or plugged into a USB port on a computer (USB 2.0 or higher).

Can more than one battery be charged at once?
Yes, up to four batteries can be charged at the same time, and full charging only takes 3–4 hours. The blue indicator light for each slot goes off when the battery is fully charged.

Can these batteries be used for small children?
Yes, both the Standard and Micro Battery Cover have a built-in safety lock, making them tamperproof. The included plastic screwdriver should be used to turn the lock. Also, the compact Micro makes SONNET the lightest audio processor for more comfort.

Please note, the lock of the Standard Battery Pack Cover cannot be locked with the Micro battery.

Can the FM battery pack be used with SONNET rechargeable batteries?
Yes, the FM battery pack for SONNET can be used for FM or direct audio input. It can be used with either size of rechargeable battery. Using an FM receiver will reduce battery life. Please note, the battery pack lock of the FM Battery Pack Cover cannot be locked with the Micro battery.

Can a full-size Standard battery cover be used with the Micro battery?
Yes, both the Standard and Micro cover can be used with the Micro battery. This allows recipients to use WaterWear for SONNET, by using the Micro battery with the Standard Battery Pack Cover. However, the battery pack lock of the Standard Battery Pack Cover cannot be locked with the Micro battery.

Can SONNET rechargeable batteries be used with WaterWear?
Yes, both batteries can be used with WaterWear for SONNET, but only with the full-sized Standard battery cover. This ensures a tight fit inside the WaterWear.

Is SONNET water-resistant with rechargeable batteries?
Yes, SONNET remains water-resistant (IP54) with rechargeable batteries. This protects SONNET against rain, sweat, and other moisture.
