Glass Mat Battery Vs Lead Acid

Absorbent glass mat agm learn what differentiate agm from other lead acid battery types.

Glass mat battery vs lead acid.

Wet cell or flooded batteries and absorbed glass mat agm batteries are both considered lead batteries and contain an electrolyte solution which causes a chemical reaction and produces electrons. This battery uses a silica gel that suspends the electrolyte between the plates. Every battery type has a different purpose and use case so let s go over the pros and cons of each. From a purely technical point of view a lead acid battery has several advantages.

The second type is the gel battery. For example a bei battery can achieve very high amperages in a concise time which is why lead acid batteries are often used in cars as starter batteries. The agm or absorbed glass mat batteries use a technology in which a glass mat holds the electrolyte between the plates. The sulfuric acid is absorbed by a very fine fiberglass mat making the battery spill proof.

You ve got flooded lead acid and sealed lead acid batteries and the latter group can be broken down into agm absorbent glass mat and gel batteries. In applications where cost was more important than the ability to mount a unit at an angle flooded lead acid remained the chemistry of choice. First and foremost the fact that the electrolyte is absorbed into fiberglass matting hence the name absorbed glass mat makes agm batteries far more resistant to vibration than flooded batteries which simply hang lead plates in an electrolyte solution inside the battery. Incredibly thin glass fibers are woven into a mat which is then soaked with battery acid to about 95 of what it can hold.

This article will focus on the differences between the main lead acid battery types used in the solar industry. Also with a lead acid battery the state of charge soc can be determined comparatively easily by the acid concentration. These batteries are recharged when put in contact with a reverse current. The most proven type of chemistry is the lead acid chemistry.

Valve regulated lead acid batteries also known as sealed lead acid batteries has two subtypes. Unlike the traditional lead acid batteries that freely flood their electrodes agm batteries have glass mats that prevent this. Advantages of lead acid batteries. Agm technology became popular in the early 1980s as a sealed lead acid battery for military aircraft vehicles and ups to reduce weight and improve reliability.

What is an absorbed glass mat agm battery. Additionally it is the function of these glass mats to avoid spillage. The only downside was that the absorbent glass mat cost more to produce therefore agm did not universally replace flooded lead acid.
