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 …
