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.

    Definitely an original ReSound charger, just like the one I got with my ReSound Quattro rechargeable hearing aids. Very quality built. Works great.

  3. Westin J. From Provo, UT.

    Lost my brand new charger that I got when I purchased my hearing aids. I think it got put in a box and thrown away when I moved! Quality heavy feel. Very small compact design. Works great. I can use it to charge my aids while traveling. Very happy with this purchase.

  4. Ruth A. From Greenville, MS.

    I received a charger when I bought my ReSound hearing aids. I felt I needed a second one when I stayed with at my daughters home. These charger are quality made and do what they are supposed to do. The pricing from HearSource was better than other places I checked with. The purchase was without issue.

    Excellent quality and build. Very easy to travel with this hearing aid charger. The system (charger and ReSound hearing aids) work well together.

  7. Douglas Springer

    This little ReSound hearing aid battery charger has been an excellent and handy performer for me. It just goes where I go. It keeps my hearing aids safe and when traveling I am much less worried about losing my hearing aids. It quickly gives a charge for an event. Mostly I just put my aids in the charger when they are not in my ears. It works great for me.
