The preferred technology in many major industries: From consumer electronics to electric cars, and many more.

Why lithium-ion? Compared with traditional battery technology, lithium-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 lithium-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.
