The VARTA button cell type 6016 (manufacturer number 06016101401) is a primary lithium battery of the CR2016 form factor, developed for applications requiring reliable and long service life. As a lithium button cell with a nominal voltage of 3 V and a capacity of 90 mAh, it is suitable for devices with low energy consumption, particularly in electronics, where continuous power supply is required for backup functions or real-time clock displays. The battery is delivered in a child-safe blister packaging that complies with the marking requirements of IEC 60086-4/Ed.5 and includes a clear warning to prevent child safety risks.

Applications

The CR2016 battery is used in a wide range of electronic devices, including watches, car keys, remote controls, medical devices, and small electronic modules. Its flat design with a diameter of 20 mm and a height of 1.6 mm makes it ideal for compact devices where space and weight are important. The high energy density and long shelf life of up to 10 years enable reliable power supply over a long period, even with low usage.

Functions and Equipment in Detail

The battery is based on lithium-manganese dioxide technology, known for its stable voltage curve and high efficiency at low current consumption. The 3-volt voltage is standard for many electronic circuits, especially for backup systems (Memory Back Up, MBU) and Real-Time-Clock (RTC) modules. The capacity of 90 mAh ensures sufficient energy supply for typical applications, with actual service life depending on load and operating conditions.

Technology Explained Simply

Lithium button cells such as the CR2016 use lithium as the anode and manganese dioxide as the cathode. This combination enables high energy density and long service life. The battery operates over a wide temperature range, making it suitable for indoor and outdoor applications. The voltage remains constant over most of the discharge cycle, which is important for the stability of electronic circuits. The packaging is designed to protect the battery from mechanical damage and ensure safety during storage and transport.

Compatibility and Accessories

The CR2016 is one of the most commonly used button cells and is accepted as a replacement battery in numerous devices. It is compatible with all devices that specify a CR2016 battery. Use in watches, remote controls, and car keys is standard. There are no specific accessories included with this battery; the packaging contains only the battery itself.

Installation and Mounting

Installation is performed by simply inserting the battery into the designated holder in the device. Polarity is standardized by the battery shape (flat side = negative pole, convex side = positive pole). The child-safe packaging requires opening by pressure or pulling to access the battery. No tools or additional components are required.

Operational Advantages

The VARTA CR2016 offers high reliability and long service life, which is particularly important for backup functions. The low height and small diameter allow use in compact devices. The shelf life of up to 10 years reduces replacement needs and ensures long-term availability. Its use in a wide range of applications makes it a universally applicable component in electronics.

The battery is delivered in a blister packaging with a quantity of 1. The packaging complies with IEC 60086-4/Ed.5 and includes a warning to prevent child safety risks. The battery colour is silver, which is typical for lithium button cells.
