Knowing how to tell the negative and positive terminals on a car battery is essential. This helps you avoid potential hazards.
Car batteries have two terminals, marked positive (+) and negative (-). Identifying them correctly is crucial for safe handling. The positive terminal is usually covered with a red cap or has a red cable attached. The negative terminal, on the other hand, often features a black cap or black cable.
Confusing the two can lead to electrical issues or even injury. By learning to distinguish these terminals, you can perform basic car maintenance tasks like jump-starting a dead battery. This knowledge ensures your safety and keeps your car running smoothly.
