Car batteries are a type of rechargeable battery that produces electric energy to your car, often called an SLI, which stands for starting, lighting, and ignition.
An automotive SLI, lead acid storage battery, powers the starter motor, the lights and the ignition system, but only when the car is not running. After the engine starts, electrical power is provided by the alternator and the energy that is not being used by the electrical systems, is put back into to the battery to keep it charged. The battery stores the electrical energy for the primary purpose of starting the engine and powering the ignition for starting, as well as running the lights, radio windows and seats, when the engine is not running.
SLI car batteries are usually lead-acid type, composed of six galvanic cells in series to produce 12-volt electrical system. Each cell provides 2.1 volts adding up to 12.6 volts at full charge. Heavier vehicles, like larger trucks or big rig tractors, which usually have diesel engines, often have have two SLI batteries in series to produce a 24-volt system or may even carry parallel strings of batteries.batteries.
Typically, lead-acid batteries composed of plates of lead and separate plates of lead dioxide, all submerged in an electrolyte solution made up of 38% sulfuric acid and 62% water. This system creates a chemical reaction releasing electrons, which then travel through conductors producing electrical current. As the battery discharges, acid in the electrolyte reacts with coposits of the plates, changing their surface to lead sulfate. Upon recharging the battery, the chemical reaction is reversed: the lead sulfate transforms into lead dioxide and lead. When the plates are restored to their original composition, the process can be repeated.
Recycling car batteries enables components to be reused thus reducing the need for new resources required for manufacturing new batteries. Recycling lead acid batteries also reduces the toxic lead from fouling landfills, and eliminates or reduces the dangers of improper LSI battery disposal.
