VARTA empowers the hearing aid of the future

Technology company VARTA and hearing aid manufacturer Eargo look back on a longstanding partnership. Their latest joint project: the Eargo 5 hearing aid with new functions and an even smaller design.

Eargo 5 is operated by a button cell based on lithium-ion technology, which, thanks to its high performance, enables future-oriented functions and properties of the hearing aid as well as a long runtime and fast charging. The rechargeable button cell has the highest energy density and can be charged within four hours. It will then deliver 16 hours of continuous power. The special design of the button cell is matched to the particular shape of the device so that it disappears invisibly in the ear when worn.

"We start every day with our vision of creating future battery solutions that enable an independent and fulfilling life in an inclusive society," says Torsten Schmerer, General Manager Microbatteries, VARTA AG. "With the development process for the Eargo 5, our engineers, technicians and electrochemists have once again proven that we can develop batteries that meet even the most demanding requirements for the most modern consumer healthcare products."

"VARTA has been a key partner for Eargo for over six years," says Rory Pynenburg, Engineering Lead Power Systems at Eargo. "With Eargo 5 functionality, it became obvious that we would need more energy density; the switch to lithium-ion not only allows this, but also makes for a much more robust solution with faster, easier charging and a goal of supporting full runtime over several years. "

In the interests of sustainability, the cell is produced on a specially manufactured production line in Germany. The Eargo 5 can be controlled via app and is based on the latest hearing aid technology.
