Varta Lithium button cell CR2016 3V

The VARTA CR2016 is a high-quality 3-volt lithium button cell and is one of the most widely used battery types for a variety of small electronic devices. Based on proven lithium manganese dioxide technology (Li-MnO2), it offers reliable and long-lasting energy supply in a very flat design. As a loose cell, it is optimal for original equipment (OEM) and for direct use by commercial users.

Highlights at a glance

• Industrial quality: Guarantees constant and reliable performance for professional devices and mass production.
• Universally applicable: One of the most popular button cells for a wide range of professional applications.
• Long shelf life: With up to 10 years shelf life, perfect for stockpiling with minimal self-discharge.
• Wide temperature range: Works reliably even under demanding thermal conditions.
• Tested reliability: Every cell meets the highest quality standards for maximum performance.

Reliable power for compact electronics

The VARTA CR2016 is the preferred power source for countless professional and industrial devices where a compact size and reliability are crucial. Its main area of use is in wireless keys for vehicles, personal and kitchen scales, calculators, small remote controls and in medical devices such as digital fever thermometers. Additionally, it serves as a backup battery in cameras and organisers.

Superior lithium manganese dioxide technology

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

Developed for industrial integration

As an unpackaged single cell, the CR2016 is intended for direct processing in industrial production (OEM) or for need-based use in service and maintenance. This reduces packaging waste and optimises workflows for professional users who rely on consistently high quality and easy handling.

FAQs about the VARTA lithium battery CR2016

What does the designation CR2016 mean?

The designation gives information about the characteristics and size of the cell. "C" stands for the lithium chemistry, "R" for the round design. The numbers "2016" denote the dimensions: 20.0 mm in diameter and 1.6 mm in height.

Can I use two CR2016 instead of one CR2032?

Although two CR2016 cells (2 x 1.6 mm = 3.2 mm) stacked have the same height as a CR2032 cell (3.2 mm) and the same voltage, this is strongly discouraged. The contact between the two cells is often unreliable and can cause malfunctions or damage to the device. Always use the battery type specified by the manufacturer.

Is this battery rechargeable?

No. This is a lithium primary battery. It must never be attempted to recharge it under any circumstances. Charging attempts are extremely dangerous and may lead to 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 provisions of the Battery Act. Please take the empty battery to the designated industrial or municipal collection points to ensure professional and environmentally-friendly recycling.
