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. Primary Lithium Button Type Range Focused on the market requirements of modern electronic devices VARTA offers high-tech primary Lithium button battery assemblies: Various PCB, SMT and wire & connector versions (e.g. with laser welding tags 0.1 mm) Low internal resistance for high pulse load High Capacity for longer running time Low self-discharge for long storage and operating time Wide temperature range (-20 °C up to 70 °C) UL Recognition Safe & reliable Outstanding application performance is guaranteed for the electronic device designer. Hundreds of battery assemblies available Global design-in teams High-tech application labs Outstanding key account customer references Worldwide branch office & distribution network ISO 9001/14001
