Tecnologia Agm Absorbent Glass Mat

The absorbent glass mat inside the battery is made out of boron silicate.

The agm material acts as a separator. At the time they were designed to be a viable alternative to the ni cad batteries which were very costly. 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. In agm sealed batteries the acid is absorbed between the plates and immobilized by a very fine fiberglass mat.

Agm are sealed for a reason absorbed glass matt there is no liquid acid in them you can t add any because of the way they re manufactured. If the case cracked nothing would leak out as the acid would remain in the mats. 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. Lead acid of any type has to be kept charged when being stored be it trickle charged over time or charged every six months at most up to full capacity.

This enables the battery to be repeatedly charged and discharged without any loss of performance. Both types of vrla batteries offer advantages and disadvantages compared to flooded vented lead acid vla batteries as well as to each other. Absorbent glass mat agm the special agm lead acid soaks up all the acid in the battery providing high cyclic stability. Instead the absorbent glass mat contains boron which makes it able to better withstand high temperatures.

Agm absorbent glass mat batteries feature fiberglass mesh between the battery plates which serves to contain the electrolyte and separate the plates. Absorbent glass mat batteries agm have been a market favorite for the past few decades. This instantly resolved a number of issues in the older design which became known as flooded lead acid. Absorbent glass mat batteries do not use the same type of glass that s used for windows.

Gel cells add silica dust to the electrolyte forming a thick putty like gel. Agm batteries are extremely resistant to vibration are totally sealed nonspillable and maintenance free. This glass mat absorbs and immobilizes the acid while still keeping the acid available to the plates. 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.

This allows a fast reaction between acid and plate material. No silica gel as is used in gelled is necessary. Learn more about agm technology. 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.
