The CR2 battery beside the 4LR44 and the CR123A

The CR2 is number 10 of the 11 IEC 60086 batteries published here, listed from AAAA to CR123A.

• Diameter (d): 15 to 15.6 mm on the CR2 battery, against 12 to 13 mm on the 4LR44 and 16 to 17 mm on the CR123A.
• Overall height (h): up to 27 mm on the CR2 battery, against 23.9 to 25.2 mm on the 4LR44 and 33.5 to 34.5 mm on the CR123A.
• Positive contact diameter (d_pos): up to 7 mm on the CR2 battery, against at least 5 mm on the 4LR44 and up to 9.6 mm on the CR123A.
• Positive contact projection (h_pos): at least 0.6 mm on the CR2 battery, against at least 0.7 mm on the 4LR44 and at least 1 mm on the CR123A.
