VARTA Battery Single-use Llithium Cr2 3v

The Varta CR2 1-BL is a single-use lithium battery providing a nominal voltage of 3 V in a compact cylindrical cell. With dimensions of approximately 15.6 x 15.6 x 27 mm and a weight of around 11 g, this battery is designed for devices requiring a small, high-energy non-rechargeable power source. The cell delivers stable output over its service life, making it suitable for intermittent and continuous use in precision equipment and portable electronics.

Advantages

The lithium chemistry offers high energy density and a long shelf life, which helps maintain capacity during storage. The compact cylindrical form factor ensures compatibility with devices that require CR2 cells. Because it is a primary (single-use) cell, it provides a reliable, maintenance-free power source until depleted. Low self-discharge characteristics and consistent voltage under moderate load contribute to dependable operation in a range of applications.

Suitable for (tasks / use cases)

• Compact cameras and camera flashes
• Portable measurement instruments and sensors
• Security devices, such as alarm sensors and motion detectors
• Flashlights and tactical lights designed for CR2 cells
• Other small electronic devices requiring a 3 V lithium CR2 cell
