14250 batteries are created using a different type of chemistry, known as lithium thionyl chloride (Li-SOCI2). This chemistry perfectly suits high-energy and high-voltage requirements. These batteries are 1/2AA size batteries, and have a nominal voltage of 3.6V. The voltage is stable for most of the battery’s life, which makes it an ideal choice for professional electronics. 14250 batteries have a low self-discharge rate for extended shelf life, and can operate effectively at extreme temperatures, between -60°C and 80°C.

14250 batteries are traditionally used across a variety of professional industries, including security and medical equipment. 14250 batteries are popular choices for wireless security systems, including window and door contacts, thanks to their long life and reliability.

This version of 14250 battery is the plain cell, and does not have axial wires, solder tags or PCB pins. These 14500 batteries are Made in China and have the silver collar around the positive top. Saft batteries produced in China have a green washer around the positive top. We hope this little tip helps you to identify the two types. The 14250 part of the part number comes from its approximate dimensions; 14mm Diameter and 25.0mm tall.
