Batteries 370

370 (SR69)

— 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, in this case, the discharge current cannot be unambiguously determined by the SR69 marking; but the designation 370 clearly indicates that we have elements of the HD format (the low-current variety is marked as 371).

Regarding other features of cells in size 370, we note that they have a diameter of 9.5 mm, a thickness of 2.1 mm and are one of the analogues of LR69 alkaline batteries.
