What is a battery?

The place where the electric energy is stored is known as a battery. Usually, electrical power needs larger areas.

But this tends to produce and consume energy at the same time. So it is essential to convert and store this energy using battery or cell.

How many types of car batteries are there?

Generally, there are two kinds of top rated car batteries. Those are known as starting and deep cycle.

The two categories convert into three sub-categories.

Those are a wet cell, the gel cell and AGM (Absorbed Glass Mat) For making your vehicle the most efficient using AGM battery is required.

What is AGM battery?

The elaboration of AGM is – Absorbent Glass Mat

It was first introduced in the time of 1980s. Day by day it is getting popular. Now it is a very common and a reliable name to the truck and SUV owners.

It was used in the military aircraft and other vehicles. It reduced the weight and also increased reliability. Powerful sulfuric acid is used here. Fiberglass mat absorbs the acid. It makes the battery spill-resistant.
