Understanding Car Batteries
Before we delve into the how-to, let’s understand the basics of car batteries. A car battery is a rechargeable electrochemical device that provides the initial power needed to start your engine. It also powers various electrical components in your car, even when the engine is off. Car batteries typically last between 3 to 5 years, but factors like driving habits, climate, and battery maintenance can affect their lifespan.

Types of Car Batteries
Car batteries come in different types, primarily classified by their construction and chemistry. The two most common types are:
- Lead-acid batteries: These are the traditional type of car batteries, known for their affordability and reliability. They are further divided into flooded, sealed, and AGM (Absorbent Glass Mat) batteries.
- Lithium-ion batteries: These newer batteries offer higher performance, lighter weight, and longer lifespan compared to lead-acid batteries. However, they are generally more expensive.
