Coin-shaped cells are thin compared to their diameter. The metal can is the positive terminal, and the cap is thenegative terminal.
IEC 60086 designation | ANSI C18 /NEDA designation | Typical Capacity mAh | Dimensions (mm) Diameter x Height | Comments |
CR927 | | 30 | 9.5 × 2.7 | This obscure type of lithium coin cell is used extensively in blinkies. |
CR1025 | 5033LC | 30 | 10 × 2.5 | Standard Discharge Current: 0.1 mA |
