Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This …
Heat tolerance of automotive lead-acid batteries
Besides the low reaction rates at low temperatures, the lowest operating temperature for lead-acid batteries is given by the risk of ice formation in the electrolyte. The freezing temperature depends on the local density of the diluted sulfuric acid electrolyte and therefore on the SOC.
