A little bit of info
The code of the lithium coin battery itself is an International Electro-Chemical (IEC) designation. The name CR2032 can be divided into two codes, the first one is the letter code 
which tells us the standard case size while the numeral code gives us information about the diameter of the cell followed by the height of the cell. In CR2032’s case, 20 refers to the fact that the cell has a diameter of 20 millimeters while 32 refers to its height of 3.2 millimeters. There are specific plug-in and solder-in CR2032 batteries as well.
