What Temperatures Does Battery Acid Freeze? Distilled water has a freezing point of 0 0 C while pure sulfuric acid has a freezing point of 10 0 C. When sulfuric acid is added to water to make the battery acid, the freezing point is depressed.
Major problems occur at temperature extremes. This is the range below 4ºC (40ºF) and above 38ºC (100ºF). The electrolyte in a fully charged battery has a freezing point of approximately –85ºF (-65ºC). However, the electrolyte in a fully discharged battery with low specific gravity has a much higher freezing point; just below 0ºC (32ºF).
This is for lead acid type batteries. Car batteries, for example. Or those which typically install in lawn tractors, ATV’s, snowmobiles, maybe in your camper, etc.. To put it another way, a lead acid battery freezing point will be -40F if it’s down 20% from a full charge. Or -22F if it’s down 40% from full charge.
The concentration of the battery acid varies with the level of charge in the battery. As the concentration, changes with discharge so do the freezing points of the solution. As can be seen the lower the concentration of sulfuric acid in the solution, the higher the freezing and vice versa.
As the state of charge in a battery decreases, the electrolyte becomes more like water and the freezing temperature increases. The freezing temperature of the electrolyte in a fully charged battery is -92º F (-69º C). At a 40% state of charge, electrolyte will freeze if the temperature reaches approximately 16º F (-9º C).
