AGM batteries are constructed with a glass fibrous separator between the plates.

This separator immobilises the electrolyte in the battery allowing AGM batteries to be completely sealed and thus maintenance free with no gas formation if the batteries are charge correctly.  

While the AGM batteries Enertec offer are all designed for deep cycling applications, their construction gives a very fast discharge at very high currents so these AGM batteries are ideal for systems that require high currents such as starting engines or running winches etc.
