Primary Lithium Button Cell Batteries for Reliable Applications
Nearly all electronics applications need safe and reliable Memory Back-Up (MBU) or Real Time Clock (RTC) batteries, especially long-term applications, such as 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 Microbattery offers a wide range of primary lithium button cell types with a voltage of 3.0V and capacities from 27mAh up to 560mAh. Various other battery assemblies with higher voltage or capacities are possible. We have for each CR type a wide range of already existing printed circuit board assembly (PCBA) designs. In addition, VARTA Microbattery 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.
