Saft LS14250 batteries with axial leads are a specific configuration of the Saft LS14250 lithium-thionyl chloride (Li-SOCl2) primary (non-rechargeable) cylindrical battery. The LS14250 model is a 1/2 AA size battery with a nominal voltage of 3.6V and a typical capacity of 1200 mAh. These batteries are known for their long shelf life, high energy density, and stable voltage output.


Axial leads are essentially wires or metal terminals that extend from the positive and negative ends of the battery, enabling easy soldering or connection to a printed circuit board (PCB) or other electronic devices. This configuration is useful for applications where space is limited or when a more secure connection is required compared to a traditional battery holder.


Saft LS14250 batteries with axial leads are commonly used in various applications, such as:


1. Industrial equipment
2. Memory backup systems
3. Utility meters
4. GPS tracking devices
5. Wireless alarm and security systems
6. Remote monitoring systems
7. Professional electronics

When handling and using these batteries, it's essential to follow proper safety precautions, as lithium-thionyl chloride batteries can be hazardous if mishandled, punctured, or exposed to high temperatures. Always consult the manufacturer's datasheet and guidelines for proper handling and usage.
