This page provides all possible meanings and translations of the word car battery
car battery, automobile battery(noun)
a lead-acid storage battery in a motor vehicle; usually a 12-volt battery of six cells; the heart of the car's electrical system
A 12 volt battery used to start an automobile
An automotive battery is a type of rechargeable battery that supplies electric energy to an automobile. An automotive SLI battery is an automotive battery that powers the starter motor, the lights, and the ignition system of a vehicle's engine, mainly in combustion vehicles. Automotive SLI batteries are usually lead-acid type, and are made of six galvanic cells connected in series to provide a nominally 12-volt system. Each cell provides 2.1 volts for a total of 12.6 volts at full charge. Heavy vehicles, such as highway trucks or tractors, often equipped with diesel engines, may have two batteries in series for a 24-volt system or may have series-parallel groups of batteries supplying 24V. Lead-acid batteries are made up of plates of lead and separate plates of lead dioxide, which are submerged into an electrolyte solution of about 38% sulfuric acid and 62% water. This causes a chemical reaction that releases electrons, allowing them to flow through conductors to produce electricity. As the battery discharges, the acid of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfate.
