The Eargo 5 hearing aid comes with new functions and an even smaller design and is operated by a button cell based on lithium-ion technology, which, due to its high performance, is able to support future-oriented functions and properties of the hearing aid as well as a long runtime and fast charging.
The rechargeable button cell provides a high energy density and can be charged within four hours. It has been designed to be able to deliver 16 hours of continuous power.
The design of the button cell is matched to the particular shape of the device so that it disappears invisibly in the ear when worn.
Commenting on the battery's design Torsten Schmerer, General Manager Microbatteries, Varta said,"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," said 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. "
According to Varta and 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.
