The litium-ion (Li-ion) battery is the preferred technology in many major industries, from consumer electronics to electric cars and more.


Why Li-ion?

Compared with traditional battery technology, Li-ion batteries deliver:

  • Longer daily runtime,
  • Longer overall lifetime,
  • Shorter charging time (together with a fast-charging option), and
  • Higher convenience for the hearing aid wearer.

Battery lifetime

The runtime of all Li-ion rechargeable batteries reduces over time. Under normal operating conditions, the battery will retain at least 80 percent of its initial capacity after two years of use. Please note that battery performance will vary depending on individual usage patterns and environmental conditions.

Will a Li-ion battery last longer if the user doesn’t charge their hearing aids every night and wait for a complete discharge before charging?

Deep-discharge cycles are not required for Li-ion batteries. The best practice is to charge the hearing aids every night and unplug the charger while not charging.

Does the battery life become shorter if using the fast charging option very frequently?

No. Thanks to our specially developed charging method, fast charging does not have any negative effect on the battery life of thehearing aids.

Is it safe to travel on an airplane with a Li-ion rechargeable hearing aid?

Yes, it is safe to wear these Li-ion rechargeable hearing aids on a plane and to bring the charger on board. It is also safe to carry the hearing aids and/or charger in luggage.

Can Li-ion rechargeable hearing aids be shipped?
