Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| LR1130 | 11.6 × 3.1 mm | Same 11.6 mm diameter, but 3.1 mm tall instead of 2.1 mm. Only if the holder fits; thinner cells can lose contact. |
| LR43 | 11.6 × 4.2 mm | Same 11.6 mm diameter, but 4.2 mm tall instead of 2.1 mm. Only if the holder fits; thinner cells can lose contact. |
| LR44 | 11.6 × 5.4 mm | Same 11.6 mm diameter, but 5.4 mm tall instead of 2.1 mm. Only if the holder fits; thinner cells can lose contact. |
