The main two types of car batteries that are available in the market are the wet cell car batteries and VRLA car batteries. All the car batteries are categorized into these two types.

The main component of the battery that it contains is a liquid electrolyte such as sulfuric acid. There are two types of wet cell batteries. The first is the SLI battery and the other one is deep cell batteries. The function of the SLI batteries is to start, light, and ignite. The deep cell batteries are mainly known as marine batteries that provide long electric discharges instead of short bursts.

On the other hand, the VRLA batteries come sealed and don’t need maintenance. So, gasses from the chemical reaction inside the battery can’t escape. There are two types of VRLA car batteries that include the gel cell battery and the absorbed glass mat battery (AGM battery). A gel is used as the electrolyte in Gel cell batteries and in the AGM batteries, thin fibers of electrolyte glass are used to form mats next to the lead dioxide plates.
