Varta lithium button cell CR2032 3V with soldering pins

The VARTA CR2032 with soldering pins is an industrially assembled 3-volt lithium button cell, optimised for direct and permanent mounting on printed circuit boards (PCBs). Based on proven lithium-manganese dioxide technology (Li-MnO2), it offers an extremely reliable and long-lasting energy supply for memory backup applications. As a loose cell ("bulk") with factory-applied soldering pins, it is the ideal component for initial equipment (OEM) of computers, industrial controllers and other professional electronic assemblies.

Highlights at a glance

• Industrial assembly: Factory-applied soldering pins for simple, quick and process-safe PCB mounting.
• Maximum reliability: The global standard for soldered CMOS and RTC backup applications.
• Extreme longevity: Up to 10 years shelf life thanks to extremely low self-discharge.
• Wide temperature range: Works reliably even under demanding thermal conditions.
• Tested quality: Every cell meets the highest quality standards for maximum performance and leak safety.

Reliable energy for data retention

The VARTA CR2032 with soldering pins is the preferred power source for buffering BIOS/UEFI settings (CMOS) and real-time clocks (RTC) on motherboards where a soldered connection is required. Its main area of application is computer technology, in industrial PCs, servers, programmable logic controllers (PLCs) and in a wide variety of embedded systems. It reliably ensures that configuration data and system time are retained for years even without external power supply.

Superior lithium-manganese dioxide technology

Lithium-manganese dioxide technology (Li-MnO2) enables a high nominal voltage of 3 volts and an extremely low self-discharge of less than 1% per year at room temperature. This guarantees maximum operational readiness even after many years of storage and a very long service life in use. This technology is the key to reliability in maintenance-free "fit and forget" applications.

Developed for industrial integration

As an unpackaged and pre-assembled single cell, the CR2032 with soldering pins is optimised directly for processing in industrial manufacturing (OEM). The soldering pins enable a stable and permanent connection to the printed circuit board. This reduces packaging waste, simplifies assembly and optimises workflows for professional users who rely on consistently high quality.

FAQs about the VARTA lithium battery CR2032 with soldering pins

What are the advantages of the permanently attached soldering pins?

The factory-applied soldering pins guarantee a high-quality and permanent connection to the cell. They save the manual or mechanical process of attaching contacts in manufacturing, which increases process reliability and shortens production time. In addition, the pin configuration is standardised and fits common PCB layouts.

What does "bulk" mean?

"Bulk" means that the batteries are supplied as loose goods in packaging units suitable for industrial use (e.g. in trays or cartons) and not in separate end-consumer packaging such as a blister pack. This is ideal for industrial manufacturing (OEM).

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 can cause fire or explosion.

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 Battery Act. As it is permanently soldered, it must as a rule be disposed of together with the entire electronic assembly as electronic waste.
