Lithium cells & batteries

Lithium primary cells have an extremely long life (3.0V or 3.6V system) and are therefore a safe and reliable long-term energy supply.



Lithium Button Cells

Nearly all electronics applications need safe and reliable Memory Back Up (MBU) or Real Time Clock (RTC) batteries. But also for long-term applications, e.g. for clocks, car key applications or remote controls where long running time, a slim design and low weight for a battery are important.

For all these needs VARTA offers a wide range of primary Lithium button cell types with a voltage of 3.0 V and capacities from 27 mAh up to 560 mAh. Various other battery assemblies with higher voltage or capacities are possible. For each CR Type we have a wide range of already existing printed circuit board assembly (PCBA) designs. In addition VARTA offers a huge number of wire and connector assembly versions. With a flexible and fast make to order supply we can make customized batteries to your individual design / printing circuit board (PCB) requirements and supply though our worldwide network.
