As long as the charging voltage stays below the gassing voltage (about 14.4 volts in a normal lead–acid battery), battery damage is unlikely, and in time the battery should return to a nominally charged state. The lead–acid battery is a type of first invented in 1859 by French physicist. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries,. The French scientist Nicolas Gautherot observed in 1801 that wires that had been used for electrolysis experiments would themselves provide a small amount of secondary current after the. Because the electrolyte takes part in the charge-discharge reaction, this battery has one major advantage over other chemistries: it is relatively simple to determine the state of charge by merely measuring the of the electrolyte; the specific. Most of the world's lead–acid batteries are (SLI) batteries, with an estimated 320 million units shipped in. DischargeIn the discharged state, both the positive and negative plates become (PbSO 4), and the loses much of its dissolved is a three-stage charging procedure for lead–acid batteries. A lead–acid battery's nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8. PlatesThe lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such. 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 disintegrate.
