What Is Absorbent Glass Mat Battery

Absorbed glass mat batteries are constructed differently than the traditional flooded battery.

What is absorbent glass mat battery. Here are a couple of things to keep in mind when maintaining your absorbent glass mat agm battery including an optima battery. Agm batteries are extremely resistant to vibration are totally sealed nonspillable and maintenance free. 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. What is agm technology.

Instead the absorbent glass mat contains boron which makes it able to better withstand high temperatures. The only downside was that the absorbent glass mat cost more to produce therefore agm did not universally replace flooded lead acid. 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. Very thin glass fibers are woven into a mat to increase the surface area enough to hold a sufficient amount of electrolyte on the cells for their lifetime.

An absorbent glass mat battery pried open to reveal the plates and acid saturated glass mat separating them. 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. Many newer battery chargers like the optima chargers digital 1200 12v performance battery charger and maintainer have microprocessors that collect information from the battery and adjust the current and voltage accordingly. In agm batteries also called starved electrolyte there is a thin ultra fine fiberglass mat sandwiched between the plates that are saturated with.

The absorbent glass mat inside the battery is made out of boron silicate. Absorbent glass mats have been around for a long period of time. Absorbent glass mat agm agm batteries differ from flooded lead acid batteries in that the electrolyte is held in the glass mats as opposed to freely flooding the plates. Some have different.

The sulfuric acid is absorbed by a very fine fiberglass mat making the battery spill. This write up covers mainly the concorde sun xtender agm s but also applies to most other brands of deep cycle agm batteries.
