Generally speaking, if you find that the batteries test reading are a little low, they are probably just a little discharged. After recharging the batteries, test them again. If those readings are low, then contact the manufacturer with the data.

Voltages were all with-in 0.016 V (2.1-2.084). The SG's were within 0.037 (1.281-1.244). Yes, the one with the lowest SG also had the lowest V. <o:p></o:p></p></div><div><p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p></div><div><p class=MsoNormal style='margin-left:.5in'>What concerns me a bit more than the few cells with lower SG is the consistent low levels of electrolyte. All cells were between 3/4" and 1-1/2" below full, which is 1/4" below the bottom of the vent well tube.... with one exception that was bang-on full. Interestingly, the one full battery was the only one with a different date code than the rest. <o:p></o:p></p></div><div><p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p></div><div><p class=MsoNormal style='margin-left:.5in'>Should the various levels of electrolyte mentioned be acceptable when a battery is brand new, straight from the mfgr?
