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.
Complete Guide to AGM, Absorbent Glass Mat Batteries
But, what does Absorbent Glass Mat (AGM) actually mean and how does that enhance the battery''s performance over standard lead acid batteries? Let''s review some basics of the SLA (sealed lead acid) battery construction.
What is an AGM battery? AGM means absorbed glass mat, and it means the battery acid inside is absorbed into fiberglass mats instead of sitting as a free-flowing liquid. The fiberglass mats spread more of the electrolyte in contact with the ultra-thin lead plates — all while cushioning the battery against knocks, bumps and vibrations.
The absorbent glass mat battery (AGM) is a recent battery technology that is increasingly common in today''s cars. It''s an alternative to the well-known wet cell, or flooded, battery that has been in use for years.
The main advantages of absorbed glass mat batteries are they are lower maintenance than flooded lead acid batteries, charge up to five times faster, have a long shelf life, and offer a depth-of-discharge of 80 percent (flooded batteries typically have a …
Sealed Lead Acid (SLA) – Absorbent Glass Mat (AGM) vs Gel
Absorbent Glass Mat (AGM) 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. This instantly resolved a number of issues in the older design (which became known as flooded lead acid).
AGM or Absorbent Glass Mat batteries are advanced maintenance-free lead-acid batteries designed to resist spilling acid and reduce water loss during usage. In addition, AGMs provide superior power, as well as vibration resistance in today''s high-electrical demand vehicles due to their optimized cell design and compression.
AGM stands for absorbent glass mat, which refers to the technology these devices use to create power. This fiberglass mat sits between the positive and negative lead plates of your battery. Then, as the name suggests, it absorbs and holds the battery acid.
Absorbed glass mat batteries, or AGM batteries, became popular in the 1980s. They were used to power motorcycles, military, aircraft, and submarines, but now you can find them in everyday cars and trucks. AGM batteries are a maintenance-free alternative to traditional flooded lead-acid batteries.
