Batteries 335

335

— 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 specific size 335, this is one of the smallest and least capacious standards in the entire series: diameter 5.8 mm, thickness 1.3 mm, capacity 5.5 mAh. The operating current of such elements is low; according to the generally accepted marking, they are called SR512, and they do not have an alkaline analogue.
