Reliable power for compact electronics

The VARTA CR1220 is the preferred power source for a wide range of professional and industrial devices where compact size and reliability are critical. Its main areas of application are personal and kitchen scales, remote keys for vehicles, calculators and medical devices such as blood glucose meters. In addition, it serves as a backup battery for retaining settings and times in a variety of electronic devices.

Superior lithium manganese dioxide technology

Lithium manganese dioxide technology (Li-MnO2) offers a high nominal voltage of 3 volts in a single cell. It is characterised by an extremely low self-discharge, which ensures a long shelf life of up to 10 years. This technology guarantees stable performance over most of the battery life and excellent performance even at fluctuating temperatures.

Developed for industrial integration

As an unpackaged single cell, the CR1220 is intended for direct processing in industrial production (OEM) or for needs-based use in service and maintenance. This reduces packaging waste and optimises workflows for professional users who depend on consistently high quality and easy handling.
 

Characteristics

FAQs on the VARTA lithium battery CR1220

What does the designation CR1220 mean?

The designation provides information about the properties and size of the cell. "C" stands for the lithium chemistry, "R" for the round shape. The numbers "1220" stand for the dimensions: 12.5 mm in diameter and 2.0 mm in height.

Is this battery rechargeable?

No. This is a lithium primary battery. It must not be recharged under any circumstances. Attempts to charge are extremely dangerous and may lead to fire or explosion.

Is this cell suitable for industrial assembly?

Yes, as a loose cell it is ideal for manual or automated assembly in volume production. For a fixed solder connection, it can also be fitted with customised solder tabs.

How should this battery be disposed of?

Batteries must not be disposed of with household waste. As an industrial battery, it is subject to the provisions of the Battery Act. Please take the empty battery to the designated industrial or municipal collection points to ensure proper and environmentally friendly recycling.
