Empowering Better Hearing
At VARTA we believe that everyone should have the possibility to live an independent and fulfilling live in an inclusive society. VARTA and Eargo have been working together for more than six years. We set out to push boundaries together. The base of our collaboration has always been a mutual partnership with the aim of developing crucial future-proof consumer products. The battery for Eargo 5 is an exclusive design by VARTA for Eargo which provides highest energy density in the smallest form factor.
Designed to be more invisible. Eargo 5 is empowered by an exceptional battery - more than five years of running time guaranteed, cycle stability and highest energy density in the smallest space with a special form factor.
Designed to be fast – the device is fully charged within four hours. With the lithium-ion technology faster and easier charging is possible while meeting the highest levels of safety.
The Development Process
Swabian engineering meets Silicon Valley. Over 15 months, VARTA's R&D team has developed a hearing aid battery that met the new challenges. Based on lithium-ion technology the cell provides highest energy density in the smallest space with a special form factor. A completely new and customised production line was developed for this purpose. The cell is made and produced environmental friendly in Germany.
Torsten Schmerer, General Manager Healthcare, VARTA AG
“We start each day to provide future battery solutions to create an independent and fulfilling live in an inclusive society for everyone. And with the development process for the Eargo 5 our engineers, technicians and electrochemists once again proved that we can develop a battery that will meet even the most challenging demands for the most advanced consumer healthcare products.”
Rory Pynenburg, Engineering Lead Power Systems, Eargo
“VARTA has been a key partner to Eargo for over 6 years. 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. We worked with VARTA to develop a custom solution. It’s rare for me to compliment companies, but VARTA really knocked it out of the park.”
