10180 batteries

10180

— this marking is carried by lithium-ion batteries (see Li-Ion in the “Type” section) in a cylindrical case with an operating voltage of 3.7 V. The number “10180” is the size of the element: the first two digits are followed by the diameter in millimeters (10 mm) , and the last three digits indicate the length of the battery in tenths of a millimeter (18 mm).

Batteries of this size are usually used in miniature electronic devices with limited space (compact flashlights, some models of headphones, etc.). Their capacity is relatively small (around 100 mAh, or even less).
