The battery casing is the outer shell that holds and protects the internal components of the car battery. It is typically made of high-quality, durable plastic that is resistant to impacts and vibrations. The casing also helps prevent the leakage of electrolyte, which is a mixture of sulfuric acid and water.
The casing also helps prevent the leakage of electrolyte, which is a mixture of sulfuric acid and water. Car batteries have two terminals: positive (+) and negative (-). These terminals are where the electrical connections between the battery and the vehicle are made.
The positive terminal is usually connected to a thick, red cable that provides a low-resistance path for electricity. On the other hand, the negative terminal of a car battery is connected to the vehicle's chassis or ground. It serves as the return path for electric current flowing through the electrical system.
