— 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 size 377 specifically, it is a low current (LD) version of the popular SR66 cells widely used in wristwatches in particular. Accordingly, the alkaline analogue of such batteries is LR66. They have a diameter of 6.8 mm and a thickness of 2.6 mm.
