Varta lithium battery CR1/2AA 3V 970mAh with solder tabs

The VARTA CR1/2AA with solder tabs (LF) is a high-performance, industrially assembled 3-volt lithium primary battery. It has been developed for professional applications that require an extremely durable and reliable power source with a connection type optimized for direct PCB mounting. Based on lithium manganese dioxide technology (Li-MnO2), it offers high energy density, extremely low self-discharge and is the ideal energy source for the original equipment (OEM) of long-life electronic devices.

Highlights at a glance

• Industrial assembly: Equipped with robust solder tabs for easy and secure PCB mounting.
• Extreme longevity: Up to 10 years shelf life thanks to extremely low self-discharge.
• High energy density: Maximum energy in a compact design for long-lasting autonomy.
• Wide temperature range: Reliable performance under extreme conditions from -40 °C to +85 °C.
• 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 energy source for "fit and forget" applications where the battery is permanently soldered to a PCB. Its main area of use is to supply memory modules (SRAM/CMOS backup) and real-time clocks (RTC) in industrial PCs and controllers (PLCs). In addition, it is ideal for use in the utility meter industry (smart metering), in safety sensors, in automotive applications 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 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 operational readiness 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 solder tabs is optimised for efficient and reliable machine or manual placement on printed circuit boards. The robust, permanently welded solder tabs ensure a permanently secure and vibration-resistant solder connection. With this cell, VARTA offers developers and manufacturers a reliable and easily integrable platform for the development of long-life and low-maintenance products.
 

Characteristics

FAQs about the VARTA lithium battery CR1/2AA with solder tabs

What does "LF" or "with solder tabs" mean?

"LF" stands for "solder tab". This means that metal strips (tabs) are already factory-welded to the positive and negative terminals of the battery. These solder tabs make it much easier to solder the battery directly onto a PCB and provide a more reliable connection than manual wire terminals.

What is the main advantage of this lithium battery?

The key advantage is the extremely long service and shelf life of up to 10 years, combined with a very wide operating temperature range. The pre-mounted solder tabs also simplify the manufacturing process, as no separate welding of contacts is required.

Is this battery rechargeable?

No. This is a lithium primary battery. It must under no circumstances be recharged. Attempts to charge are extremely dangerous and may result in fire or explosion.

For which soldering methods 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 may damage the cell. Please refer to the manufacturer's processing instructions.

How must this battery be disposed of?

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