What is a glass mat battery.

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. Agm means absorbed glass mat and it s a specific type of lead acid battery. 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.

However they re more affordable. 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. 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. Lead acid batteries don t hold a charge as long as an absorbed glass mat battery and are less tolerant of deep discharge.

Absorbed glass mat batteries are constructed differently than the traditional flooded battery. In agm batteries also called starved electrolyte there is a thin ultra fine fiberglass mat sandwiched between the plates that are saturated with. What is agm technology. It absorbs the sulfuric acid with a very fine fiberglass mat and makes the battery spill proof.

Agm batteries are extremely resistant to vibration are totally sealed nonspillable and maintenance free. All optima batteries are agm also known as absorbed glass mat batteries but the question consumers often ask is how many years do agm batteries last that s a valid question considering agm batteries typically cost significantly more than their flooded counterparts. 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 fibers that.

This write up covers mainly the concorde sun xtender agm s but also applies to most other brands of deep cycle agm batteries.
