ReSound LiNX Quattro Hearing Aid Charger Case Technology

In the modern world where almost every piece of technology is accompanied by a charger, it’s only natural that hearing aids have become rechargeable also. Just like you would charge your smartphone overnight, the same goes for rechargeable digital hearing aids, so you’ll never have to miss a special moment because a battery needs to be changed.

While rechargeable hearing aids have been available for some time, they weren’t popular because of their low power output. Thanks to advancements in hearing aid technology, today’s best rechargeable hearing aids give you power that lasts longer than a full day.

Traditionally, the rechargeable hearing aid batteries were produced with Nickel metal hydride (NiMH). Now, the best rechargeable hearing aids use Lithium-Ion battery technology, which has completely changed the performance of rechargeable digital hearing aids.

Rechargeability for advanced hearing aids is enabled by the use of medical grade Li-ion batteries that are sealed in hearing aids. This technology offers multiple user benefits and excellent hearing aid battery performance. Furthermore, it provides better protection of vulnerable electronic parts and contacts in the hearing aids. Because of smart battery technology, users get feedback on battery and charging status from the charger, hearing aids, and the ReSound Smart 3D app for iOS and Android smartphones. The rechargeable ReSound LiNX Quattro And Resound KEY hearing aids and the ReSound LiNX Quattro/KEY Charger Case has been very positively reviewed by users.
