Varta Lithium button cell CR2430 3V

Description

Product information

The VARTA CR2430 is a high-quality 3-volt lithium button cell with high capacity, developed for reliable and particularly long-lasting power supply in demanding electronic devices. Based on proven lithium manganese dioxide technology (Li-MnO2), it offers high energy density in a flat design. As a loose cell ("bulk"), it is optimally suited for initial (OEM) equipment and for direct use by commercial users in large quantities.

Highlights at a glance

  • High capacity: Offers a significantly longer runtime than smaller CR20xx series button cells.
  • Industrial quality: Guarantees constant and reliable performance for professional equipment and serial production.
  • Extreme longevity: Can be stored for up to 10 years thanks to extremely low self-discharge.
  • Wide temperature range: Works reliably even under demanding thermal conditions.
  • Tested reliability: Each cell meets the highest quality standards for maximum performance and leak safety.

Reliable energy for demanding electronics

The VARTA CR2430 is the preferred energy source for a wide range of devices where long life and high capacity are critical. Its main area of use is in remote controls with extended functions (e.g. with display), modern wireless car keys, medical devices such as blood glucose meters and smart home sensors (e.g. door and window contacts), which must function for years maintenance-free.

Superior lithium manganese dioxide technology

The 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 usability even after many years of storage. This technology ensures stable performance over much of the battery's life, which is essential for reliable operation of sensitive electronics.

Developed for industrial integration

As an unpackaged single cell, the CR2430 is intended directly for processing in industrial (OEM) production or for on-demand use in service and maintenance. This reduces packaging waste and optimises workflows for professional users who depend on consistently high quality and ease of use.

FAQs about the VARTA lithium battery CR2430

What does the designation CR2430 mean?

The designation gives information about the properties and size of the cell. "C" stands for the lithium chemistry, "R" for the round shape. The numbers "2430" stand for the dimensions: 24.5 mm in diameter and 3.0 mm in height.

What does "bulk" mean?

"Bulk" means that the batteries are delivered 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 production (OEM).

Is this battery rechargeable?

No. This is a lithium primary battery. It must never be recharged. Charging attempts are extremely dangerous and can 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 relevant industrial or municipal collection points to ensure proper and environmentally friendly disposal.
