— a five-digit numeric marking without letter indexes is used for lithium-ion batteries with a nominal voltage of 3.7 V. They are very popular in devices equipped with electric motors and consuming a lot of energy — quadcopters, radio-controlled models, airsoft drives, etc. All such batteries have a cylindrical shape, but the size is just indicated by numbers: first the diameter (the first two digits, in millimetres), then the length (the remaining three digits, in tenths of a millimetre). In this case, the size of the battery is 14 mm thick and 50 mm long. This corresponds to the dimensions of an AA battery, however, due to the difference in voltage, the 14500 and AA cells are not interchangeable. And, as befits batteries, they can be recharged.
