Absorbent glass mat agm technology agm or absorbent glass mat is an advanced lead acid battery that provides superior power to support the higher electrical demands of today s vehicles and start stop applications.
Tecnologia agm absorbent glass mat.
Gel cells add silica dust to the electrolyte forming a thick putty like gel.
This allows a fast reaction between acid and plate material.
Absorbent glass mat batteries do not use the same type of glass that s used for windows.
There are two primary types of vrla batteries absorbent glass mat agm and gel cell.
Agm battery technology relates to absorbent glass mat which is a technology that began to widespread in the early 1980s primarily in the applications of military aircraft vehicles and backup power.
If the case cracked nothing would leak out as the acid would remain in the mats.
No silica gel as is used in gelled is necessary.
Absorbent glass mat agm the special agm lead acid soaks up all the acid in the battery providing high cyclic stability.
At the time they were designed to be a viable alternative to the ni cad batteries which were very costly.
In agm sealed batteries the acid is absorbed between the plates and immobilized by a very fine fiberglass mat.
Absorbent glass mats have been around for a long period of time.
Both types of vrla batteries offer advantages and disadvantages compared to flooded vented lead acid vla batteries as well as to each other.
The absorbent glass mat inside the battery is made out of boron silicate.
Absorbed glass mat agm technology batteries are a type of valve regulated lead acid vrla battery that use a material manufactured from very fine glass fibers.
Agm batteries are extremely resistant to vibration are totally sealed nonspillable and maintenance free.
This enables the battery to be repeatedly charged and discharged without any loss of performance.
This instantly resolved a number of issues in the older design which became known as flooded lead acid.
Absorbent glass mat batteries agm have been a market favorite for the past few decades.
This glass mat absorbs and immobilizes the acid while still keeping the acid available to the plates.

The agm concept discovered in the 1970s uses glass fibers woven into a mat which is 95 saturated in acid and then placed between the plates.
Instead the absorbent glass mat contains boron which makes it able to better withstand high temperatures.
The agm material acts as a separator.
Though they were mainly used in military vehicles as a source of back up power and heavy vehicles such as long distance trucks nowadays they have more diversified uses.
