[Vwdiesel] Battery Source

[Ron Schroeder]

Optima's are not Gel batteries.  They are AGM  (Absorbed Glass Mat) 
batteries and are far superior to gel batteries for high current 
applications.

The self discharge of AGM batteries is better than flooded.  I started my 
old truck with one that had not been charged for over 2 years.

AGM batteries tend to have lower internal resistance than flooded batteries 
so they can put out more current for short periods of time than flooded 
batteries.

Under normal operation, they last several times longer than conventional 
batteries.
