Lead-acid batteries will accept more current if the temperature is increased and if we accept that the normal end of life is due to corrosion of the grids then the life will be halved if the temperature increases by 10ºC because the current is double for every 10ºC increase in temperature.
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.”
Lead acid batteries function using an electrochemical process in which lead plates react with an electrolyte. As the temperature rises and a battery absorbs heat, the process speeds up exponentially. This results in an increase in plate corrosion, self-discharge, and over a prolonged period of time, sulfation.
Heat issues, in particular, the temperature increase in a lead-acid battery during its charging has been undoubtedly a concern ever since this technology became used in practice, in particular in the automobile industry.
In any case, good quality lead-acid batteries will not normally fail due to drying out. Drying out is not relevant to vented types and we can use the Arrhenius equation to give an estimate of the life when the operational temperature is different to the design temperature.
Thus, the maximum voltage reached determines the slope of the temperature rise in the lead-acid battery cell, and by a suitably chosen limiting voltage, it is possible to limit the danger of the “thermal runaway” effect.
