Varta Lithium round cell CRAA 3V with axial connections

The VARTA CRAA with axial connection wires is a high-performance, industrially pre-assembled 3-volt lithium primary battery in AA size. It has been developed for professional applications that require an extremely durable and reliable power source with a connection type optimised for PCB mounting. Based on lithium-manganese dioxide technology (Li-MnO2), it offers high energy density, extremely low self-discharge and is the ideal power source for the initial equipment (OEM) of long-life and low-maintenance electronic devices.

Highlights at a glance

• Industrial assembly: Equipped with robust, axial connection wires for simple and secure PCB mounting.
• Extreme longevity: Up to 10 years shelf life thanks to extremely low self-discharge.
• High capacity: Provides a very high energy reserve of 2000 mAh for long-lasting autonomy.
• Wide temperature range: Reliable performance under extreme conditions from -40°C to +85°C.
• High 3V voltage: Ideal for modern electronic circuits in AA size.

Reliable energy for long-term applications

The pre-assembled VARTA CRAA is the preferred power source for "fit and forget" applications, where the battery is permanently soldered onto a printed circuit board. Its main field of application is supplying smart meters (smart metering for water, gas, electricity), industrial controllers (PLC), security sensors, alarm systems and the backup of memory modules (SRAM/CMOS backup) in professional electronics.

Superior lithium manganese dioxide technology

Lithium manganese dioxide technology (Li-MnO2) is the key to this cell's outstanding performance. It enables a high nominal voltage of 3 volts in the common AA size and an extremely low self-discharge of less than 1% per year at room temperature. This ensures maximum readiness for use even after many years of storage. The technology is also known for its high safety and reliability in industrial environments.

Designed for industrial integration

As an industrially pre-assembled cell, the CRAA with axial terminals is optimised for efficient and reliable machine or manual placement on PCBs. The robust connection wires ensure a permanently secure and vibration-proof soldered connection. With this cell, VARTA offers developers and manufacturers a reliable and easy-to-integrate platform for the development of durable and low-maintenance products.

FAQs on the VARTA lithium battery CRAA with axial connections

What does "axial wire" mean?

Axial connection wires are wires that are routed centrally from both flat ends (poles) of the cylindrical cell, i.e. along the longitudinal axis of the battery. This configuration is ideal for horizontal mounting and for passing the wires through holes in a PCB (Through-Hole Technology, THT).

Is this battery rechargeable?

No. This is a lithium primary battery. Under no circumstances should it be attempted to recharge it. Charging attempts are extremely dangerous and may cause fire or explosion.

Can I use this battery as a replacement for a normal 1.5V AA battery?

No, definitely not. This CRAA cell has a nominal voltage of 3 volts, whereas standard AA batteries (alkaline, lithium, NiMH) have 1.5 volts. It should only be used in devices that are explicitly designed for the 3-volt lithium type CRAA, as the higher voltage would destroy other devices.

How should this battery be disposed of?

Batteries must not be disposed of in household waste. As an industrial battery, it is subject to the provisions of the Battery Act. Please return the empty battery to the designated industrial or municipal collection points to ensure proper and environmentally friendly recycling.
