   ummm. AGM Batteries have slightly different characteristics to the   
   batteries the charger you're considering will work well with insofar as   
   charging requirements.   
   I'm guessing here, but IF the batteries are basically equal in their   
   resistance etc, then 12 Volt chargers might work well enough - depends   
   on just what actual voltage the charger belts out in response to the   
   internal resistance of the victim batteries - in other words how well   
   the charger is 'regulated'. All bets are off with the exceedingly cheap,   
   brightly coloured and nasty devices laughingly called chargers, commonly   
   found in the local accessories store right beside the plastic wheel   
   trims and furry steering wheel covers:-)   
      
   We have a few battery experts about this group , hang on, THESE groups.   
   Will be interesting to see their response.   
   Natch, my suggestion is  that if you actually  shelled out 'ard earned   
   for the batteries, you'd be treating them to a real live computer   
   controlled tricked up charger.   
   What do you intend to use this massive power source for, may I ask?   
      
      
   Wow,
