Batteries LR59

LR59

— the LR index denotes compact 1.5 V “coin” batteries made using alkaline technology. These are simpler and cheaper analogues of silver-oxide cells of the SR series (it is also “three hundredth”, a typical example is size 357, it is also SR44). LR batteries have a relatively low capacity, they are prone to a rapid voltage drop as they are discharged, and they do not handle high load currents well. On the other hand, such cells are noticeably cheaper than silver-oxide ones, and for devices with an even low energy consumption, they are the best option.

Specifically, the LR59 batteries have a diameter of 7.9 mm and a thickness of 2.6 mm, thus being one of the smallest in the series. They can also be found under the AG2 and G2 markings; and silver-oxide counterparts are 396 cells (high discharge current) and 397 (low current).
