    The common CR2032 battery is 20 mm diameter and 3.2 mm thick, where the first two digits is the diameter and the last two digits are thickness. A CR2025 is the same 20 mm diameter but 2.5 mm thick. The heavy electrical demands of many of these devices make lithium batteries a particularly attractive option.
