What Is Absorbent Glass Mat Battery

Agm batteries are extremely resistant to vibration are totally sealed nonspillable and maintenance free.

What is absorbent glass mat battery. 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. The only downside was that the absorbent glass mat cost more to produce therefore agm did not universally replace flooded lead acid. Absorbent glass mat agm learn what differentiate agm from other lead acid battery types 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. The sulfuric acid is absorbed by a very fine fiberglass mat making the battery spill.

The absorbent glass mat inside the battery is made out of boron silicate. In applications where cost was more important than the ability to mount a unit at an. 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. Some have different.

An absorbent glass mat battery pried open to reveal the plates and acid saturated glass mat separating them. This write up covers mainly the concorde sun xtender agm s but also applies to most other brands of deep cycle agm batteries. Instead the absorbent glass mat contains boron which makes it able to better withstand high temperatures. Absorbed glass mat batteries are constructed differently than the traditional flooded battery.

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. Here are a couple of things to keep in mind when maintaining your absorbent glass mat agm battery including an optima battery. Absorbent glass mats have been around for a long period of time. In agm batteries also called starved electrolyte there is a thin ultra fine fiberglass mat sandwiched between the plates that are saturated with.

Absorbent glass mat batteries do not use the same type of glass that s used for windows. 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.
