Understanding Car Batteries and Jump-Starting
The Basics of Car Batteries
Car batteries are essential components that provide the initial power needed to start your engine. They store electrical energy in the form of chemical energy and convert it into electrical energy when needed. Most modern vehicles use 12-volt lead-acid batteries. These batteries consist of lead plates immersed in a sulfuric acid electrolyte solution. When the battery is charged, chemical reactions occur that deposit lead sulfate on the plates, storing energy. When you turn the ignition, the chemical reactions reverse, releasing the stored energy as electrical current that powers the starter motor.
