Understanding Car Batteries
A car battery is a crucial component of your vehicle’s electrical system. It provides power to start the engine, lights, and accessories. A dead car battery can be caused by a variety of factors, including old age, corrosion, faulty alternator, or a faulty battery itself. It’s essential to understand how car batteries work and what you can do to prevent them from dying.
A car battery is made up of several components, including:
- Positive and negative terminals
