To decode a battery number, first identify the letters and numbers in the code: the letters usually indicate the battery type or chemical composition (like "CR" for lithium coin cells), while the numbers specify the battery's size (diameter and height in millimeters). For example, "CR2032" means a lithium coin cell battery that is 20mm in diameter and 3.2mm thick. Always check the manufacturer's datasheet for exact specifications.
