The idea of an electrolyte- even a weak one- freezing above 0degC is a nonsense, although MINUS 6.8degC would be right for an electrolyte with SG around 1.1 (i.e. partially discharged) so I suspect the "+" should be a "-". However, I haven't read it up....so perhaps there has been a recent tweak to the Laws of Physics I haven't heard about.
