     I'm a little confused with my battery's amps.  I have a solar lighting   
   system connected for the front lights (driveway)and the rear stairs (for the   
   dogs).  Now with winter approaching I decided to set my C12 controller to run   
   dusk to dawn.  According    
   to an analog ammeter connected in line the system draws 2 amps (double checked   
   with a clamp on ammeter).    
      
     I have 4 t105's connected to give me 440 amps @ 12 volts, they are 1 year   
   old.  2 days ago checked SG (all were good and close to each other), and   
   watered. I have only once drawn them down (exercise?).     
      
     Now my confusion.  They started out from float yesterday.  This AM the   
   voltage was down to 12.3 volts.  Counting 14 hrs on time I drew 28 amp hours   
   from the battery's. In theory I should be able to run this for 2 weeks or so   
   (wouldn't, but if I wanted    
   to run them empty).  12.3 is close to 50% of the battery lets say 200 amps?     
      
     Is there something basic I am missing? From reading here over the years I   
   know voltage is a poor way of determining SOC, but voltage seems low to a   
   layman.   
      
   Thanks
