Car batteries are prepared for storage by charging and cleaning deposits from the posts. ![]() Car batteries in storage may be monitored and periodically charged to retain their capacity. Leaving car batteries discharged will shorten their lifespan, or make them unusable if left for a long time (usually several years) sulfation eventually becomes irreversible by normal charging. With the plates restored to their original condition, the process may now be repeated.Ĭar batteries tend to last longer when stored in a charged state. Charging car batteries reverses this chemical: the lead sulfate reforms into lead oxide and lead. As car batteries discharge, the acid of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfate. This causes a chemical reaction that releases electrons, allowing them to flow through conductors to produce electricity. Lead-acid car batteries are made up of plates of lead and separate plates of lead dioxide, which are submerged into an electrolyte solution of about 35% sulfuric acid and 65% water. Heavy vehicles such as highway trucks or tractors, often equipped with Diesel engines, may have two car batteries in a series for a 24 volt system, or may have parallel strings of car batteries. Each cell provides 2.1 volts for a total of 12.6 volt at full charge. SLI car batteries are usually lead-acid type, and are made of six galvanic cells in series to provide a 12 volt system. Car batteries may also be traction car batteries, which are used as the main power source of electric cars.
