— the "three hundredth" 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 marking 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 marking 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 marked as 370, LD as 371.
As for the 346 type specifically, with an average diameter of 7.9 mm by the standards of the series, such elements have a thickness of only 1.3 mm. They give out a low operating current and are generally marked as SR712; no alkaline analogue is provided.
