   Eveready states in their literature that the "open" voltage (unloaded) of such   
   a cell is 1.5 to 1.6 volts - as a matter of the specific device in question.   
   Suggesting that the loaded voltage will be lower. They state, typically, at   
   1.55V for a 1.6V    
   battery. There is also a temperature chart in their literature, but it is   
   applied only to storage and longevity-in-storage.    
      
   9 x 1.6 = 14.4, so you are definitely within the range even with the lowest   
   reading given.   
   Typical accuracy (DC) on an RS meter (today) is +/- 0.5% - as advertised.   
   Meaning some may be better, but should not be worse. As yours are likely older   
   models, +/- 0.5% is likely optimistic.    
   0.5%  x 14.4 = 0.072   
   Meaning that your range-of-readings should be somewhere between 14.472 and   
   14.328 for that particular group of nine (9) button cells.    
      
   Oh, RIGHT!  You are comparing apples (liFe) cells to oranges (ZnAgO). Simple   
   enough:  Go to the Manufacturer and get the nominal unloaded and loaded   
   values. Measure with the meters-in-hand. That which is the closest is the   
   benchmark. If the others are    
   consistent, there is your margin-of-error.
