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. Zinc–carbon battery - Wikipedia

   en.wikipedia.org/wiki/Zinc–carbon_battery

   Zinc–carbon batteries of various sizes. A zinc–carbon battery (or carbon zinc battery in U.S. English) is a dry cell primary battery that provides direct electric current from the electrochemical reaction between zinc (Zn) and manganese dioxide (MnO 2) in the presence of an ammonium chloride (NH 4 Cl) electrolyte.

4. Duracell - Wikipedia

   en.wikipedia.org/wiki/Duracell

   Duracell Inc. is an American manufacturer of alkaline batteries, specialty cells, and rechargeables; it is a wholly owned subsidiary of Berkshire Hathaway. The company has its origins in the 1920s, through the work of Samuel Ruben and Philip Mallory, and the formation of the P. R. Mallory Company . Through a number of corporate mergers and ...

5. Battery leakage - Wikipedia

   en.wikipedia.org/wiki/Battery_leakage

   Battery leakage. A nickel–cadmium Varta barrel battery that has leaked onto the mainboard of a Korg Poly-61, causing massive corrosion to circuit board traces and legs of integrated circuits. Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment ...

7. Dry cell - Wikipedia

   en.wikipedia.org/wiki/Dry_cell

   Dry cell. A dry cell is a type of electric battery, commonly used for portable electrical devices. Unlike wet cell batteries, which have a liquid electrolyte, dry cells use an electrolyte in the form of a paste, and are thus less susceptible to leakage . The dry cell was developed in 1886 by the German scientist Carl Gassner, after development ...

9. Zinc–air battery - Wikipedia

   en.wikipedia.org/wiki/Zinc–air_battery

   A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air. During discharge, a mass of zinc particles forms a porous anode, which is saturated with an electrolyte. Oxygen from the air reacts at the cathode and forms hydroxyl ions which migrate into the zinc paste and form zincate ( Zn ...
