This boils down to about 2.4 V / cell, which is fairly high for a PbAc  
battery. But please understand that a UPS is not a measuring  
instrument. More often than not, the reported resolution is much more  
than the accuracy of the measurement justifies. So unless your  
batteries wear out quickly, you can safely ignore this.
