Lead–acid battery
OverviewConstructionHistoryElectrochemistryMeasuring the charge levelVoltages for common usageApplicationsCycles
The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
