To read a battery code, first identify the alphanumeric code printed on the battery, which typically indicates the battery's size, chemistry, and sometimes its manufacturing date. For example, in a code like "CR2032," "CR" denotes the lithium chemistry, "20" indicates the diameter in millimeters, and "32" represents the thickness in tenths of a millimeter. Additionally, some batteries have date codes that may require consulting the manufacturer's guide to interpret production or expiration dates.
