How Does Temperature Affect Battery Life?

High temperatures can cause the capacity of a battery to decrease, while low temperatures can cause the state of charge to decrease. It is important to note that the effect of temperature on battery life depends on the type of battery. For example, lithium-ion batteries have a higher energy density and nominal capacity than lead-acid batteries.

Lead-acid battery

OverviewCyclesHistoryElectrochemistryMeasuring the charge levelVoltages for common usageConstructionApplications

Lead-acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate …
