Upgrade or downgrade
Same size, different chemistry. Read the verdict before you buy.
| Cell | Chemistry | Voltage | Verdict |
|---|---|---|---|
| LR527 | alkaline | 1.5 V | Downgrade Works, but runs out sooner. Avoid in watches and medical devices. |
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| SR512 | 5.8 × 1.2 mm | Same 5.8 mm diameter, but 1.2 mm tall instead of 2.7 mm. Only if the holder fits; thinner cells can lose contact. |
| SR516SW | 5.8 × 1.6 mm | Same 5.8 mm diameter, but 1.6 mm tall instead of 2.7 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 2.7 mm. Only if the holder fits; thinner cells can lose contact. |
