If your vehicle fails to start one day, one of the possible causes could be a dead or faulty battery. While drivers know that all cars need this equipment, few understand what gives batteries the power to operate a vehicle. To provide you with a better understanding of how car batteries work, here are some of their components and their functions. 

What Are the Main Parts of a Car Battery? 

1. Terminal

The battery contains six galvanic cells that hold electrical energy. The terminal connects to the positive and negative straps on the ends of the cells, which connect the battery to the car’s electrical system. This component is made of lead, so it’s an excellent corrosion-resistant conductor.

2. Plates

Within each cell are lead plates. They consist of stacks with alternating positive and negative charges that connect through a cast-on strap welded to the component. When submerged in the acidic bath, they trigger a chemical reaction. This produces electrons that travel through conductive terminals and become electricity to power the car.

3. Battery Acid

Car batteries contain sulfuric acid that’s diluted with water. It acts as an electrolyte solution. The lead plates are submerged in the acid to convert electrical energy into chemical energy and vice versa. The substance is highly corrosive and dangerous, but it’s sealed within the galvanic cells.

4. Cast-On Strap

These short, lead straps are welded to the top of each cell. They allow an electrical charge to flow to the terminals. When the cells produce energy, the straps help the power flow efficiently throughout the battery.

5. Battery Case

The case is the container that holds the battery in place. It contains the plates, electrolyte, and cast-on strap. Its design keeps all the components steady under the engine’s vibration. Its protection can extend the battery’s lifespan.
