The VARTA lithium coin cell type CR2430 is a primary lithium-metal cell developed for applications with high energy demand and long operating times. As a coin cell with a nominal voltage of 3 V, it is suitable for a wide range of electronic devices, particularly for applications requiring reliable power supply over extended periods. The cell is delivered in child-safe packaging compliant with the requirements of standard IEC 60086-4/Ed.5, and features leak-proof technology ensuring safe handling and disposal.

Applications

The CR2430 cell is designed for devices requiring stable and long-lasting power supply. This includes Memory Back Up (MBU) and Real Time Clock (RTC) systems in computers and embedded systems. It is also used in watches, car keys, remote controls, calculators, cameras, and smart home devices with high power consumption. The flat design and low weight make it particularly suitable for compact devices where space and weight are important.

Functions and Features in Detail

The cell offers a guaranteed shelf life of 10 years, meaning it can be stored over a long period without significant capacity loss. It operates over a wide temperature range, making it suitable for use in various environments. The embossing in the form of the VARTA light cone serves product identification and is a feature of brand identity. The packaging is designed to be child-safe, preventing accidents from accidental access.

Technology Explained Simply

The cell is based on lithium-metal technology, enabling high energy density and long service life. The nominal voltage of 3 V is standard for many electronic circuits. The capacity is 280 mAh, indicating the amount of electrical charge the cell can deliver. The cell is primary, meaning it is not rechargeable, and serves as a single-use battery. The leak-proof construction prevents electrochemical substances from leaking in case of damage or aging.

Compatibility and Accessories

The CR2430 cell is compatible with all devices requiring a coin cell with dimensions of 24.5 mm diameter and 3 mm height. It is delivered in a blister pack with a quantity of 1.

Installation and Mounting

Mounting is done by simply inserting the cell into the designated holder in the device. Polarity is defined by the flat and convex sides of the cell, with the convex side corresponding to the positive polarity. The cell is designed for use in devices that allow direct mechanical fixation. No special tools or additional mounting components are required.

Operational Advantages

The cell offers high reliability and long service life, extending maintenance intervals and stabilizing device operation. The leak-proof technology reduces the risk of device damage due to leakage. The child-safe packaging increases safety during storage and handling. The high energy density enables compact device designs in which the cell is used.
