How Does a Car Battery Work?
A car battery is an essential element for the operation of the vehicle. This electrochemical device stores chemical energy and converts it into electrical energy, which is essential for starting the engine and powering the car's electrical systems, such as lights, climate control and control units. Furthermore, it ensures the correct functioning of these devices even when the engine is off or in the initial stages of starting.
What Are the Types of Car Batteries?
There are different types of batteries, each designed for specific needs:
- Traditional lead-acid batteries: The most common, suitable for vehicles with low energy demands.
- AGM (Absorbent Glass Mat) batteries: Ideal for cars with start-stop systems thanks to their resistance to charge and discharge cycles.
- EFB (Enhanced Flooded Battery) batteries: An intermediate solution between traditional and AGM batteries, also suitable for start-stop systems.
- Lithium batteries: Used in electric and hybrid vehicles, lightweight and with high energy density.How to Read the Information Written on the Battery?
Each battery has a label with key information:
- Voltage (V): Typically 12V for most cars.
- Capacity (Ah): Indicates the amount of energy it can store; for example, 60 Ah equals 60 amps for one hour.
- Cranking Amps (CCA): Measures the ability to start the engine in cold temperatures.
- Polarity: Specifies the position of the positive and negative poles.
Choosing a battery with specifications compatible with your vehicle is essential to ensure optimal operation.When to Change the Battery?
The average lifespan of a battery is between 3 and 5 years, but can depend on factors such as quality, vehicle usage, and weather conditions. Signs that a battery needs replacing include difficulty starting, dim lights, and frequent need for charging. Regular checks can help prevent problems.
What is the Difference Between Regular and Start-Stop Batteries?
Conventional batteries are designed to provide power during engine start-up, but are not suited to handle frequent charge and discharge cycles. In contrast, AGM and EFB batteries, specifically designed for start-stop systems, are better able to withstand continuous on-off cycles. These batteries also support the vehicle's electrical systems when the engine is off (for example, at traffic lights) and ensure greater durability and reliability in such conditions.
