Compatible replacements
- SR44 x2: Two stacked SR44 silver cells give 3.1 V in the same 11.6 mm diameter and combined height; some devices accept either arrangement.
Buying and replacement notes
The alias 2L76 gives away its party trick: it occupies exactly the space of two stacked LR44/SR44 cells and delivers comparable voltage (3 V versus 3.1 for two silver cells). Many cameras list both options. The lithium single cell wins on shelf life and cold performance, which is why sight makers specify it, while two 357s can be easier to find locally in a pinch.
