The CoinPower Generation A4.

Expanding horizons of engineering.

CoinPower A4 Generation

The VARTA CoinPower A4 opens up numerous opportunities for the future development of wireless and mobile devices in a wide range of application areas. From wireless headphones and medical devices through to measurement and safety systems and automotive applications. We manufacture batteries as prototypes or in large series, both as standard versions and in line with customer specifications.

Areas of application


Whether in hearables (e.g. earbuds), fitness tracker, heart rate monitors or health data measuring, our Lithium-Ion button cells are the ideal solution for your customers, giving them more independence on the move. Our concepts for power supply in the headset market, as well as in the sports and fitness sector, stand out thanks to their durability, reliability and innovative possibilities and have been setting standards for years.


There is hardly any other area where absolute reliability is as important as in medical applications. Itis no wonder that more and more customers are relying on our products: insulin pumps, medical dosing systems and health monitoring – these are all areas where our innovations from fully automated production are used. We have therefore become important partners in many areas of medical and are also setting new standards in this field.


Interconnecting devices, machines and sensors globally is no longer a futuristic dream but has long become reality thanks to the "Internet of Things" (IoT). The "Internet of Things" is in the process of revolutionising our daily lives. Precise and reliable energy solutions are essential for the functioning of the growing and increasingly differentiated IoT applications.

Smart Home

Digitalisation is also making strides in the home, opening up a multitude of new, practical possibilities. Devices are connected to the Internet and networked with each other. Locks can also be unlocked, lights turned off and appliances controlled remotely via access controls. This also requires smart energy solutions that can be relied upon.

Automotive Applications

Whether eCall, tracking systems, intelligent keys or toll collect systems - our application possibilities also excel in the automotive sector. They have particularly high temperature stability thanks to their special sealing system, which eliminates any risk to electrical circuits, for example.
