CR2020 equivalents
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| CR2012 | 20 × 1.2 mm | Same 20 mm diameter, but 1.2 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| CR2016 | 20 × 1.6 mm | Same 20 mm diameter, but 1.6 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| CR2025 | 20 × 2.5 mm | Same 20 mm diameter, but 2.5 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| CR2032 | 20 × 3.2 mm | Same 20 mm diameter, but 3.2 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| CR2040 | 20 × 4 mm | Same 20 mm diameter, but 4 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
| CR2050 | 20 × 5 mm | Same 20 mm diameter, but 5 mm tall instead of 2 mm. Only if the holder fits; thinner cells can lose contact. |
