- Stable voltage: Constant 3-volt voltage over almost the entire service life of the battery.
Reliable energy for long-term applications
The assembled VARTA CR1/2AA is the preferred power source for "fit and forget" applications where the battery is permanently soldered onto a PCB. Its main area of application is the supply of memory modules (SRAM/CMOS backup) and real-time clocks (RTC) in industrial PCs and controllers (PLCs). It is also ideally suited for use in the metering industry (smart metering), in security 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 outstanding performance of this cell. It enables a very 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 an industrially pre-assembled cell, the CR1/2AA with axial connections is optimised for efficient and process-safe machine or manual mounting of PCBs. The robust connection wires provide a permanently secure and vibration-resistant soldered connection. With this cell, VARTA offers developers and manufacturers a reliable and easy-to-integrate platform for the development of durable, low-maintenance products.

FAQs about the VARTA lithium battery CR1/2AA with axial connections
What does "axial connections" mean?
Axial connections are connecting wires that are led out from the centre of the two flat ends (terminals) of the cylindrical cell, i.e. along the longitudinal axis of the battery. This configuration is ideal for horizontal mounting and for inserting the wires through holes in a printed circuit board (Through-Hole Technology, THT).
What is the main advantage of this lithium battery?
The key advantage is the extremely long life and storage duration of up to 10 years, combined with a very wide operating temperature range. The pre-attached connection wires also simplify the manufacturing process, as no separate spot welding of contacts is necessary.
Is this battery rechargeable?
No. This is a lithium primary battery. Under no circumstances should you attempt to recharge it. Recharging attempts are extremely dangerous and can lead to fire or explosion.
For which soldering procedures is this assembled cell suitable?
This cell is intended for hand and wave soldering. Use in reflow soldering is not recommended, as the high temperatures can damage the cell. Please refer to the manufacturer's processing notes.
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 hand in the empty battery to the designated industrial or municipal collection points to ensure proper and environmentally friendly recycling.
