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.

The runtime of all Li-ion rechargeable batteries reduces over time. The estimates are based on fresh lithium-ion rechargeable battery capacity. Under normal operating conditions, the battery will retain up to 80% of its initial capacity after 2 years of use. Please note that battery performance will vary depending on individual usage patterns and environmental conditions.
