VARTA at the digital Embedded World 2021

At Embedded World, the trade fair for embedded systems technologies, which this year takes place virtually due to COVID-19, VARTA is presenting the new generation of the VARTA CoinPower® A4 with the claim "Expanding Horizons of Engineering". Like its predecessor versions, the microbattery offers the highest energy density in the smallest space - which is now even higher than before.

The new generation of lithium-ion button cells is used in pioneering technologies for wireless and mobile devices in a wide range of applications: in wearables such as earbuds or fitness trackers, in devices for the Internet of Things, in medicine and smart homes and smart cities as well as in the automotive sector. With lithium-ion button cells, it is possible to produce ever more compact and smaller devices with a high level of convenience for the consumer.

Philipp Miehlich, General Manager OEM at VARTA: „With the latest generation of lithium-ion cells, we are going one step further and VARTA is once again showing why we are innovation and technology leaders in many areas. Our customers can enable even more functions and even longer runtimes for their products thanks to the more powerful generation A4 button cells. It is thanks to our high competence in research and development as well as our high production standards that we can make leading products even better. VARTA produces in Germany on machines that we have largely developed and designed ourselves. This ensures that we have full control along the entire value chain.”

Information on the new generation VARTA CoinPower® A4 can also be found in the video.
