The majority of these car batteries use a lead-acid chemical reaction. These plates are submerged in sulphuric acid, which acts as a catalyst and triggers a chemical reaction between them. This reaction produces electrons, which generate electricity. The electricity then flows from the battery to start your car engine.
How does a car battery charge?
The battery receives the electrical charge from the car’s alternator. The alternator Is a component made up of a magnetic coil and rod, inside the car’s engine, that converts the mechanical energy into electrical energy. The electrical energy is fueled through the battery, giving it a charge.
How do car batteries last so long?
Heat facilitates the chemical reaction car batteries use to generate electricity, but it also increases the rate of battery degradation. In cooler northern climates, a battery may last five years or longer, but in hot southern locales, a car battery will typically last approximately three years.
How does the car battery go?
In total, a battery emits 12 volts of power, with each cell emitting two volts. Both battery grids go into a sulphuric acid solution, which activates a reaction between them. But how the battery work is that the acid solution catalyzes the emission reaction, which produces the ions and lead sulfate.
