The concentration levels of sulfuric acid in the solution cannot be increased so much as it will corrode the battery plates leading to loss of battery capacity and power. A fully charged battery will be able to withstand extremely low temperatures unlike a partially charged or a fully discharged battery. Is Battery Ruined If It Freezes?
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.
Sulfuric acid is a crucial component of lead-acid batteries. It is used as an electrolyte, which facilitates the chemical reaction that produces electrons. The acid concentration in the electrolyte solution is essential to the battery’s performance. If the concentration is too low, the battery may not produce enough power.
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.
Sulfuric acid in lead-acid batteries is usually a 30% aqueous solution in the fully charged state, so its entropy will be different. The entropy value for this diluted sulfuric acid is 128.1 J∙K −1 ∙mol −1 and it will significantly affect the conclusions about cell heat balance .
From the calculations based on values for diluted sulfuric acid, we state that the purely thermodynamic process during discharge of the battery is endothermic (as opposed to the findings by Křivík , which were performed assuming 100% H 2 SO 4), thus contributing to cooling of the system.
