The term “alkaline” refers to the chemical electrolyte inside the casing, which generates a steady flow of electrons until the chemicals lose their potency. Alkaline AA batteries: Standard alkaline AA batteries are the most common type found on store shelves and come at an affordable price.There are three basic types of AA batteries to choose from: The manufacturer will often include recommendations for a specific type of AA battery to use for maximum performance or those types to avoid in order to prevent damage. It is important to determine the ideal type of AA battery to power different devices.
An insulated wire provides this connection, and the result is an electrical current that can power small motors or other electronics. The repelled electrons want to flow to the positive cathode but require a connection to form a closed loop.
During a chemical reaction in the electrolyte, excess electrons flow toward the anode, but they have nowhere to go. In the space between these two poles is a chemical solution known as an electrolyte. The negative end is also called an anode. The positive end of an AA battery is also called a cathode.
