lithium coin cell batteries. These are quite common for small electronics, but there's a specific logic to those numbers that’s helpful to know if you ever need a replacement.
Here is the breakdown of what those markings mean and how these batteries work:
Understanding the "CR1216" Code
The alphanumeric code on the battery isn't just a random serial number; it’s a set of physical dimensions:
C: This stands for Lithium, specifically lithium manganese dioxide. It tells you the chemistry and the nominal voltage (typically 3V).
R: This stands for Round.
12: This is the diameter in millimeters (12mm).
16: This is the height (thickness) in tenths of millimeters. So, a 16 is 1.6mm thick
