LR66

— 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, LR66 batteries are 6.8mm in diameter and 2.6mm thick. This size is quite popular in digital wristwatches. It can be marked as V4GA, AG4, G4 or GP77A and has two silver-oxide counterparts — 376 (high discharge current) and 377 (low current).
