Introduction
This TSIB provides background on the differences and similarities between AGM (Absorbed-electrolyte Glass Mat) batteries and flooded lead acid
batteries. It also explains charging procedures performed by the GR8 Battery Diagnostic Station (SST P/N 00002-MCGR8) and its ability to charge
AGM batteries at higher current levels then a standard battery charger.

Battery Comparison
Differences between AGM and flooded lead acid batteries:
^
AGM batteries have thin, sponge-like, glass mat separators that absorb all liquid electrolytes.
^
Flooded lead acid batteries have free, liquid electrolyte all around the plates and separators.
^
Flooded lead acid batteries can easily release gas that is formed during a charge, while AGM battery life is diminished if gas is formed during
charging.
Similarities between AGM and flooded lead acid batteries:
^
Both share the exact same lead acid chemistry.
^
Both share the same charge and discharge principles.
^
Both are safely charged by vehicle charging systems.
^
When discharged, both can be recharged at high current levels.
