PANASONIC Lithium battery CR-2/3A 3V 1650mAh

The PANASONIC CR-2/3A is a high-performance 3-volt lithium primary battery, developed for professional and industrial applications with the highest demands on 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 ("bulk"), 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 storage thanks to extremely low self-discharge.
• High energy density: Maximum energy in a compact design for long-lasting self-sufficiency.
• Wide temperature range: Reliable performance under extreme conditions from -40 °C to +85 °C.
• High capacity: 1650 mAh for energy-intensive applications with long runtime requirements.
• Industrial top quality: Developed and manufactured for demanding OEM applications and safety-relevant electronics.

Reliable energy for long-term applications

The PANASONIC CR-2/3A is the preferred energy source for "fit and forget" applications where a battery change is not intended for years. Its main area of use is the supply of memory modules (SRAM/CMOS backup) and real-time clocks (RTC) in industrial PCs and controllers (PLCs). It is also ideal for use in the metering industry (smart metering for water, gas, electricity), in safety sensors, in the automotive sector and in medical technology.

Superior lithium manganese dioxide technology

Lithium manganese dioxide technology (Li-MnO2) is the key to the exceptional performance of this cell. It enables a high nominal voltage of 3 volts and an extremely low self-discharge rate of less than 1% per year at room temperature. This guarantees maximum readiness for use 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 CR-2/3A is optimised for industrial processing and configuration for battery solutions. Its robust construction and high quality ensure process-safe integration in final devices. With this cell, PANASONIC offers developers and manufacturers a reliable and high-performance platform for developing long-lasting and low-maintenance products.
 

Characteristics

FAQs about the PANASONIC Lithium Battery CR-2/3A

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 broad operating temperature range. It reliably supplies energy for many years and is therefore ideal for maintenance-free devices in which the battery is permanently installed.

Is this battery rechargeable?

No. This is a lithium primary battery. It must not under any circumstances be attempted to recharge it. Attempts to charge are extremely dangerous and can lead to fire or explosion.

How is this cell integrated into a device?

As an industrial raw cell, the CR-2/3A is usually configured with welded solder pins or solder tabs so that it can then be securely soldered onto a printed circuit board. It can also be used in special battery holders.

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

This means that the cell has the same diameter as an A cell, but only about two thirds of its height. This compact design enables use in space-critical applications that require more capacity than a 1/2 AA cell.

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 proper and environmentally friendly recycling.
