Ⅰ. CR2450 Battery Introduction

CR2450 button lithium manganese dioxide battery is named according to IEC standards. Among them, C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode.

CR- means that the shape of the battery is button-shaped. 2450 represents the standard size of the battery. The first two digits of the button battery name (one digit below 10mm) are the diameter, and the last two digits are the thickness. The 24 in 2450 means the diameter is 24mm, the 5 means the battery height is 5mm, and the 0 means the battery is cylindrical in shape. 

CR2450 batteries are mercury free, so they are environmental friendly.
