Upgrade or downgrade
Same size, different chemistry. Read the verdict before you buy.
| Cell | Chemistry | Voltage | Verdict |
|---|---|---|---|
| SR920SW | silver oxide | 1.55 V | Upgrade Upgrade: steadier voltage, longer life. |
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| LR45 | 9.5 × 3.6 mm | Same 9.5 mm diameter, but 3.6 mm tall instead of 2.1 mm. Only if the holder fits; thinner cells can lose contact. |
| LR916 | 9.5 × 1.6 mm | Same 9.5 mm diameter, but 1.6 mm tall instead of 2.1 mm. Only if the holder fits; thinner cells can lose contact. |
| LR927 | 9.5 × 2.6 mm | Same 9.5 mm diameter, but 2.6 mm tall instead of 2.1 mm. Only if the holder fits; thinner cells can lose contact. |
