Storage Battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to achieve recharging through reversible chemical reactions. It usually refers to lead-acid batteries. It is a type of secondary battery and its working principle is to use external electrical energy to regenerate internal active substances during charging, store electrical energy as chemical energy, and convert chemical energy into electricity again when needed for discharge It can output power, such as commonly used mobile phone batteries in daily life

It uses a lead substrate grid (also known as a grid) filled with sponge like lead As the negative electrode, a lead substrate grid filled with lead dioxide is used as the positive electrode, and dilute sulfuric acid with a density of 1.26-1.33g/mlg/ml is used as the electrolyte. During discharge, the metal lead is the negative electrode, which undergoes oxidation reaction and generates lead sulfate. Lead dioxide is the positive electrode, which undergoes reduction reaction and generates lead sulfate. When charging with direct current, the two poles generate elemental lead and lead dioxide respectively. After removing the power source, it returns to the state before discharge. Composition of the state of  Lead-acid batteries can be repeatedly charged and discharged, and their individual voltage is 2V. A battery is a battery pack composed of one or more individual cells, abbreviated as a battery. The most common type is 6V. Other types of batteries include 2V, 4V, 8V, and 24V. For example, a battery used in automobiles (commonly known as a battery) consists of six lead-acid batteries connected in series to form a 12V battery pack

For traditional dry load lead-acid batteries (such as automotive and motorcycle dry load batteries), distilled water should be added after a period of use to maintain a density of about 1.28g/ml of dilute sulfuric acid electrolyte. For maintenance free batteries, distilled water is no longer needed until the end of their service life
