2. Alkaline battery - Wikipedia

   en.wikipedia.org/wiki/Alkaline_battery

   An alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide . Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline ...

3. Rechargeable alkaline battery - Wikipedia

   NiCd, the first alkaline battery. In 1899, a Swedish scientist named Waldemar Jungner invented the nickel–cadmium battery, a rechargeable battery that has nickel and cadmium electrodes in a potassium hydroxide solution; the first battery to use an alkaline electrolyte. It was commercialized in Sweden in 1910 and reached the United States in 1946.

7. AA battery - Wikipedia

   en.wikipedia.org/wiki/AA_battery

   An AA battery is composed of a single electrochemical cell that may be either a primary battery (disposable) or a rechargeable battery. Several different chemistries are used in their construction. The exact terminal voltage, capacity and practical discharge rates depend on cell chemistry; however, devices designed for AA cells will usually ...
