— 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 18 mm in thickness and 35 mm in length. And, as befits batteries, they can be recharged.
