Understanding Car Batteries
A car battery is a critical component of a vehicle’s electrical system, providing power to start the engine and support various accessories such as lights, radio, and wipers. Most modern cars use a 12-volt lead-acid battery, which consists of six cells connected in series. The battery’s primary function is to store electrical energy, which is then released to power the vehicle’s electrical systems.
Types of Car Batteries
There are several types of car batteries available in the market, each with its unique characteristics and advantages. Some of the most common types include:
- Lead-Acid Batteries: These are the most common type of car battery and are widely used in most vehicles.
- AGM (Absorbed Glass Mat) Batteries: These batteries use a special type of separator to absorb sulfuric acid, making them more durable and resistant to vibration.
- Enhanced Flooded Batteries (EFB): These batteries use a special type of separator to improve the flow of electrolyte and increase the battery’s lifespan.
- Start-Stop Batteries: These batteries are designed for vehicles with start-stop technology, which shuts off the engine when the vehicle comes to a stop.
Key Components of a Car Battery
A car battery consists of several key components, including:
- Positive Terminal (Post): This is the terminal where the positive cable is connected.
- Negative Terminal (Cable): This is the terminal where the negative cable is connected.
- Cells: These are the individual units that make up the battery.
- Electrolyte: This is the substance that facilitates the flow of electrical energy between the cells.
