SR512 equivalents

Direct replacements

The same cell under another code. Any of these fits, whatever the brand.

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.
