Understanding Car Batteries:
A car battery is an electrochemical device. It converts chemical energy into electrical energy. It starts the engine and powers electrical components when off. The two main types of car batteries are:
-
Lead-acid batteries are the most common type, known for their reliability and affordability. They are divided into two categories: flooded and sealed (AGM).
-
Absorbent Glass Mat (AGM) batteries are a more advanced type of maintenance-free battery. They are lead-acid batteries. They are designed for deep cycling. They suit vehicles with high electrical demands.
Importance of a Quality Battery
Choosing a quality battery is essential for several reasons:
-
Reliability: A reliable battery ensures that your vehicle starts every time without fail.
-
The right battery can boost your vehicle’s performance in extreme weather.
