— all cells referred to as "CR plus 4 digits" are thin disposable batteries (colloquially referred to as "coins" or "coins"), made using lithium technology and having a nominal voltage of 3V. They are used in technology that consumes relatively little energy and requires durable batteries; the life of one “tablet” without replacement is usually calculated in months, and in some cases even years. The four-digit index corresponds to the size of the battery — the diameter in millimetres (the first two digits) and the thickness in tenths of a millimetre (the second two digits). Accordingly, the CR2016 element has a diameter of 24 mm and a thickness of 5 mm; it is one of the largest "coin" form factors.
