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.
Or glass mat batterys better.
Agm stands for absorbent glass mat which means as much as lead fleece to the usa.
First and foremost the fact that the electrolyte is absorbed into fiberglass matting hence the name absorbed glass mat makes agm batteries far more resistant to vibration than flooded batteries which simply hang lead plates in an electrolyte solution inside the battery.
With the agm batteries the electrolyte is completely soaked in a glass mat separator whereby the acid can not move.
In this case a glass fiber fleece is saturated with sulfuric acid.
Unlike the traditional wet batteries agm batteries only hold a small amount of acid which is entirely absorbed by the glass mat.
This design brings a lot of advantages.
In the gel battery however the acid is mixed with silica.
Lead acid batteries don t hold a charge as long as an absorbed glass mat battery and are less tolerant of deep discharge.
However they re more affordable.
An agm absorbed glass mat battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates.
Unlike normal car batteries there is no more liquid in the battery which could leak in an accident for example.
Absorbed glass mat agm.
Although the acid is still immobile here the agm battery can work better under pressure.
Therefore damage or impact to the battery will not harm you.
