Research & Technology

As a globally recognized technology leader, VARTA's constant drive is to define the future of battery technology with innovative products to enable a more independent life.

The demand for mobile energy sources is becoming ever higher. Most applications are becoming smaller, lighter and smarter. At the same time, the resources used so far are becoming scarcer and alternative processes and materials have to be found. Through continuous investment in research and development, VARTA aims to maintain this balance between resource-saving products and technological progress, relying on a wide range of research projects aimed at sustainable marketable products.


„Intelligent battery solutions and their smart use will determine our future and change the status quo in many areas of life.  It's great to be working on this with my team.“

Thomas Mertens, Head of R&D VARTA AG


Research locations

VARTA AG conducts the main part of its research work at a total of three locations. Several safety and in-house chemical laboratories as well as prototype construction support the international VARTA development team in their daily work. The process development team takes over the realization of the projects and the implementation in highly automated large-scale production. The electronics and software of the battery packs are also developed in-house in order to react as quickly as possible to changing market requirements.

As an innovation leader, VARTA AG also works closely with research institutes, government institutions and universities.


One of the first patents of Adolph Müller, the founder of today's VARTA, was granted in Switzerland in 1892.

As of today*, VARTA has 472 granted patents. In addition, there are 23 utility models and 19 design patents.
