Frequently Asked Questions
What are the different types of car batteries?
There are primarily two main types of car batteries: flooded lead-acid batteries and AGM (Absorbent Glass Mat) batteries. Flooded batteries are the most common and traditional type, containing liquid electrolyte that needs to be checked and topped up periodically. AGM batteries are sealed and use a fiberglass mat to absorb the electrolyte, making them spill-proof and more resistant to vibration. Other less common types include gel batteries and EFB (Enhanced Flooded Battery) batteries.
How does a car battery work?
A car battery stores chemical energy in the form of lead and sulfuric acid. When the engine is running, the alternator replenishes the battery’s charge. When the engine is off, the battery provides electrical power to start the engine and power the car’s electrical systems. The chemical reaction between the lead plates and sulfuric acid produces a flow of electrons, which creates electricity.
Why should I choose an AGM battery over a flooded battery?
AGM batteries offer several advantages over flooded batteries. They are spill-proof, maintenance-free, and more resistant to vibration, making them ideal for vehicles with demanding driving conditions. AGM batteries also tend to have a longer lifespan and can withstand deep discharges better. However, they are typically more expensive than flooded batteries.
How do I know when my car battery needs to be replaced?
Several signs indicate a failing car battery, including difficulty starting the engine, dim headlights, slow engine cranking, and warning lights on the dashboard.
