Varta Lithium Battery CR2/3AA 3V 1,35Ah

The VARTA CR2/3AA is a high-performance 3-volt lithium primary battery developed for professional and industrial applications with the highest requirements for longevity and reliability. Based on lithium manganese dioxide technology (Li-MnO2), it offers high energy density, extremely low self-discharge and a very wide operating temperature range. As a loose cell, it is the ideal energy source for the initial equipment (OEM) of durable and low-maintenance electronic devices.

Highlights at a glance

• Extreme longevity: Up to 10 years of storage thanks to extremely low self-discharge.
• High energy density: Maximum energy in a compact form for prolonged autonomy.
• Wide temperature range: Reliable performance under extreme conditions from -40 °C to +85 °C.
• High capacity: 1.35 Ah for energy-intensive applications with long run time requirements.
• Industrial top quality: Developed and manufactured for demanding OEM applications and safety-relevant electronics.

Reliable energy for long-term applications

The VARTA CR2/3AA is the preferred power source for "fit and forget" applications where battery replacement is not planned for years. Its main area of use is for supplying security sensors (e.g. in alarm systems), smart meters (smart metering for water, gas, electricity), industrial control systems (PLC) and the backup of memory modules (SRAM/CMOS backup). It is the optimal solution for all self-sufficient, wireless devices.

Superior lithium manganese dioxide technology

Lithium manganese dioxide technology (Li-MnO2) is the key to the outstanding performance of this cell. It 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 serviceability even after many years of storage. The technology is also known for its high safety and reliability in industrial environments.

Developed for industrial integration

As a highly specialised single cell, the CR2/3AA is optimised for industrial further processing and assembly into battery solutions. Its robust construction and high quality ensure reliable integration into end devices. VARTA offers developers and manufacturers a reliable and powerful platform for the development of durable and low-maintenance products with this cell.
 

Characteristics

FAQs about the VARTA Lithium Battery CR2/3AA

What is the main advantage of this lithium battery?

The crucial advantage is the extremely long service and storage life of up to 10 years, combined with a very wide operating temperature range. It supplies reliable energy for many years and is therefore ideal for maintenance-free devices in which the battery is permanently built in.

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 can lead to fire or explosion.

How is this cell integrated into a device?

As an industrial raw cell, the CR2/3AA is usually assembled with attached solder pins or solder tabs to then be safely soldered onto a circuit board. It can also be used in special battery holders.

What does the size designation "2/3 AA" mean?

This means that the cell has the same diameter as a standard AA battery, but only about two thirds of its height. This compact form allows use in space-critical applications.

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 respective designated industrial or municipal collection points to ensure proper and environmentally friendly recycling.
