Batteries LR57
prices on 5 modelsLR57
— 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, LR57 batteries are 9.5mm in diameter and 2.6mm thick. Their alternative marking are V7GA, AG7, G7; and the silver-oxide counterparts are known as 395 (low discharge current) and 399 (high current).
