Glass mat agm battery construction.

The plates are tightly compressed into each cell and held under pressure in the plastic case. Agm batteries are comprised of lead plates advanced glass mat and acid inside the battery case. Agm means absorbed glass mat and it s a specific type of lead acid battery. Ultra thin glass fibers soak up all the electrolyte water and sulfuric acid into thin pillows cushioning the lead plates.

It absorbs the sulfuric acid with a very fine fiberglass mat and makes the battery spill proof. This mat is then packed in between the plates and slightly compressed then welded soldered in place. They are the gm in agm absorbed glass mat batteries. This material s design enables the fiberglass to be saturated with electrolyte and to store the electrolyte in a dry or suspended state rather than in free liquid form.

The cast lead straps that connect the cells of an optima battery also work better and last longer than the weaker inter cell welds found on many car batteries. Each plate is wrapped in a separator to avoid short circuits then a piece of glass matting is put on each side of the plate then another plate is added and the agm matting is installed again. Agm absorbent glass mat batteries feature fiberglass meshbetween the battery plates which serves to contain the electrolyte and separate the plates. Agm battery construction in agm batteries the positive and negative plates are separated by an absorbent glass mat that absorbs and holds the battery s acid and prevents it from flowing freely inside the battery.

Gel cells add silica dust to the electrolyte forming a thick putty like gel. Instead of the free flowing liquid inside of a regular car battery the agm carries its charge in soaked sponges coating the lead plates. In agm batteries also called starved electrolyte there is a thin ultra fine fiberglass mat sandwiched between the plates that are saturated with battery acid to about 95 of what they can hold. Optima agm batteries use pure lead in their construction which performs better and lasts longer than the recycled lead used in many batteries today both flooded and agm.

Absorbed glass mat agm an agm absorbed glass mat battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates. Unlike the traditional lead acid batteries that freely flood their electrodes agm batteries have glass mats that prevent this. There are two primary types of vrla batteries absorbent glass mat agm and gel cell.
