Easy charging - what is it

Phonak rechargeable hearing aids are fully featured hearing aids with a built in Lithium-ion rechargeable battery. The rechargeable hearing aids offers 24 hours* of battery life on a single charge.

Easy charging - why to use it

With rechargeable batteries, clients benefit by having hassle-free hearing without having to change batteries or carry extra batteries with them. Using a Lithium-ion battery, there is the additional benefit of reduced deterioration and degradation of the battery over time without affecting hearing aid performance. Furthermore by removing the battery door, this has improved the durability of the hearing aid. Hearing care professionals also benefit by having more counselling time that can be spent on topics not relating to battery changing and maintenance.

Easy charging - why to use it

Remove the hearing aids from the Phonak charger and press the push button for 3 seconds until the indicator light briefly flashes green. The hearing aids are now switched on and ready for use. At the end of the day, simply place the hearing aids into the charger. They will click into the slots and automatically switch off. The green indicator light flashes slowly to indicate charging. Once the light stops flashing and remains solid the hearing aids are fully charged and ready to for use. Charging time for a completely depleted hearing aid is 3 hours.
