Indeed, unless you want to calculate when to replace the batteries when their capacity falls between a certain limit, but I don't think one can expect that sophistication from low- and medium end UPSes. > However, seeing a maximum voltage of 3V on a unit that is nominally > 96V seems wrong, even if that is 8 batteries of 12V each. Could there > be a conversion error? Perhaps 2.3V should be 23V? I think it reports the single cell voltage. In that case, a value of 2.3V would be about the right voltage for a fully charged cell (in float operation that is) and 1.8V the lower discharge limit (lower than that you risk permanent damage). I would expect a better resolution in the voltage though if this is true. With 0.1V resolution, there are not an awful lot of steps between a fully charged battery and an empty one. _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
