AA Battery

The AA battery also called a double A or Mignon (French for "dainty") battery is a standard size single cell cylindrical dry battery. The IEC 60086 system calls it size R6, and ANSIC18 calls it size 15.[1] Historically, it is known as SP7 (Standard Power 7) or HP7 (High Power 7) in official documentation the United Kingdom, though it is colloquially known as a "double A battery".AA batteries are common in portable electronic devices. An AA battery is composed of a single electrochemical cell that may be either a primary battery (disposable) or a rechargeable battery. The exact terminal voltage and capacity of an AA size battery depend on cell chemistry; however, devices designed for AA will usually only take 1.5 V unless specified by the manufacturer.Introduced in 1907,[2] the AA battery size was standardized by the American National Standards Institute (ANSI) in 1947, but it had been in use in flashlights and electrical novelties before formal standardization. ANSI and IEC Battery nomenclature gives several designations for cells in this size, depending on cell features and chemistry.Ref:- https://en.wikipedia.org/wiki/AA_battery
