Batteries LR54
prices on 45 modelsLR54
— 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, LR54 batteries are 11.6mm in diameter and 3.1mm thick. Marking options for individual manufacturers — V10GA, AG10, RW49, G10, GP189A; silver-oxide counterparts — 389 (high discharge current) and 390 (low current).
