— the "300" series includes miniature 1.5 V "coin" batteries — analogues of the LR series alkaline cells, made using more advanced silver oxide technology. This technology is more expensive, but allows to achieve greater capacity, more stable voltage, and resistance to high discharge currents (although nominal currents can be relatively low).Note that the most popular designation for silver oxide batteries is SR with two numbers (the same as in LR cells of the same size. However, our catalog uses a purely digital three-digit designation as a basis. It is more accurate, since it takes into account not only physical dimensions , but also the discharge current — high (HD) or low (LD); and it significantly affects the specifics of using the battery. For example, it is impossible to determine the discharge current by marking SR69; but according to the rules of the "three hundredth" series, such elements of the HD discharge format will be designated as 370, LD as 371.
As for the 337 size specifically, it is miniature even compared to its "brothers": diameter is 4.8 mm (the smallest in the series), thickness is 1.6 mm (only slightly larger than that of 335 batteries). According to the generally accepted (and official) marking, such elements are called SR416; the alkaline analogue is designated, respectively, as LR416. Operating Current — Low (LD).
