To decode a battery number, identify the type and size from the alphanumeric code—letters usually indicate the battery chemistry (like "CR" for lithium coin cells), while numbers specify the dimensions or model (such as "2032" meaning 20mm diameter and 3.2mm thickness). Check the manufacturer's datasheet or a battery code chart for exact details, as formats may vary.
