Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| SR516SW | 5.8 × 1.6 mm | Same 5.8 mm diameter, but 1.6 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact. |
| SR521SW | 5.8 × 2.1 mm | Same 5.8 mm diameter, but 2.1 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact. |
| SR527SW | 5.8 × 2.7 mm | Same 5.8 mm diameter, but 2.7 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact. |
