What is the difference between AGM and GEL?

The major difference is that in the AGM, the electrolyte is fully soaked into a special absorbed glass mat separator which immobilises the acid, whereas in the GEL batteries the acid is mixed with Silica to form a GEL also immobilising the acid. The benefits of AGM over GEL are that with the use of absorbed glass mat, the battery pack can be operated under a greater operating pressure so improving cyclic durability. With GEL, similar pack pressure can not be used so durability is usually provided by increased paste density which is good for life but not as good for high rate startability performance as required for automotive applications.
