what temp does a car battery freeze
Making the world better, one answer at a time. A car battery freezes at different temperatures depending on its state of charge. When fully charged the electrolyte is mostly Sulfuric acid and it will not freeze easily, something as low as minus 60.When discharged the acid turns to mostly water and the freezing will start at much warmer temperatures, minus 10 can give a problem with a flat battery.2 deg fah +++ (That's the freezing-point of pure water.) Adding antifreeze lowers the freezing-point, to a temperature depending on the make and dilution-the values for a s â¦ pecific anti-freeze will be on its container label.
