The numbers on a battery typically indicate its size, capacity, and voltage. For example, in a battery labeled "CR2032," "CR" refers to the chemical composition (lithium), "20" represents the diameter in millimeters, and "32" indicates the thickness in tenths of a millimeter. Additionally, other numbers may refer to the battery's voltage or capacity in milliampere-hours (mAh).
