Batteries are the lifeblood of any vehicle. They provide power so that the engine can start and the headlights can shine. Without a battery, your car would be nothing more than a hunk of metal sitting in your driveway.
A battery is made up of two parts: a positive terminal and a negative terminal. The terminals are connected to each other by an electrical circuit, which is completed by another component called an electrolyte solution. A car battery typically has six cells that are connected together to form one large cell with six terminals (two positives and two negatives).
The electrolyte solution inside the cells is what allows electricity to flow from one terminal to another. When you connect your car’s battery to an external power source, such as jumper cables or a charger,
