Understanding Car Batteries
A car battery is a rechargeable battery that stores electrical energy in the form of chemical energy. It’s designed to provide a high surge of power to start the engine and power the electrical systems. The battery consists of six cells, each containing lead plates and sulfuric acid. When the battery is connected to the electrical system, the lead plates react with the sulfuric acid to produce electricity.
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 of car batteries include:
- Lead-Acid Batteries: These are the most common type of car battery and are made of lead plates and sulfuric acid.
- AGM (Absorbed Glass Mat) Batteries: These batteries use a special type of glass mat to absorb the acid and provide better performance and durability.
- Enhanced Flooded Batteries (EFB): These batteries use a special type of acid that provides better performance and durability than traditional lead-acid batteries.
- Lithium-Ion Batteries: These batteries use lithium ions to store energy and provide better performance and durability than traditional lead-acid batteries.
Car Battery Maintenance
Regular maintenance is essential to ensure the longevity of your car battery. Some of the most important maintenance tasks include:
- Checking the battery terminals for corrosion and cleaning them as needed.
- Checking the battery water level and adding distilled water as needed.
- Checking the battery age and replacing it every 5-7 years.
- Avoiding deep discharging of the battery by keeping the engine running for a few minutes after starting the car.
How Often Do I Change My Car Battery?
