2.43 VDC per cell is 14.58 VDC 

2.47 VDC per cell is 14.82 VDC

The difference is 0.24 VDC (for a 12 VDC system)

This can be the difference between a wasted set of sulfated batteries 
and a good healthy set of batteries. 

I know many wrenches who who never accept these low of a absorption 
voltage for a system - I think the batteries would never be fully 
charged by a generator.  I know many who routinely set the 
bulk/absorption setpoint up in the 15 to 15.4 VDC level with non-sealed 
batteries.
