lead battery is a battery that uses a lead plate filled with spongy lead as a negative pole, a lead plate filled with lead dioxide as a positive pole, and
22 to 28% of the thin sulfuric acid as an electrolyte. When charging, electrical energy is
converted
into chemical energy, which is converted into electrical energy when discharged. When the battery discharges, the metal lead is negative, oxidation reaction occurs, is oxidized to lead sulfate, lead dioxide is positive, the reduction reaction occurs, is reduced to lead sulfate. When the battery is charged with direct current, the poles produce lead and lead dioxide, respectively. After removing the power supply, it returns to its pre-discharge state, forming a chemical battery. Lead batteries are batteries that can be recharged and discharged repeatedly, called secondary batteries. Its voltage is 2V, usually three lead batteries in series to use, the voltage is 6V. The car uses six lead batteries in series into a 12V battery pack. Lead batteries should be replenished with sulfuric acid after a period of use, so that the electrolyte remains containing 22 to 28% of the sulphate.
