 * __HOW DO BATTERIES WORK?__**

Answer the question below, append new answers to the top of this page. _ __Response 1:__ Avery S There are many different types of batteries one of the more common batteries is a dry cell battery, which is a non-rechargeable battery used for flashlights, remotes and various other things. Dry cell batteries work because they have a chemical formula called the electrolyte that creates electrons. These electrons travel together in what’s called an electrical current between two metal plates called electrodes (two medal parts on each send of a traditional battery, + and -). Separating the electrons is a chemical solution called electrolyte. When the electrodes are connected it sets off the chemical reaction creating the electrons. Because the electrons are negatively charged when you hook the battery up to a circuit the electrons flow out the negative electrode providing electricity to the circuit. Eventually the cells or the chemical reaction runs out and there are no more electrons. With rechargeable batteries there are not only primary cells (that run out after reaction) there are secondary cells that can be recharged by flowing electricity into them (Plugging into a charger). When a rechargeable battery is hook up to an electricity source what happens is the chemical reaction is reversed restoring the electrolyte (the chemical salutation that creates the electrons).
