Charging and Discharging of Lead Acid Battery

Lead–acid batteries lose the ability to accept a charge when discharged for too long due to sulfation, the crystallization of lead sulfate. They generate electricity through a double sulfate chemical reaction. Lead and lead dioxide, the active materials on the battery''s plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery rech

What is the Discharge Power of a Battery? (Discharge Rate)

The discharge voltage of a lead acid battery is typically 2.1 volts per cell, while lithium-ion batteries have a discharge voltage of around 3.6 volts per cell. NiCd and NiMH batteries have slightly higher discharge voltages of 1.2 and 1.4 per cell, respectively. When a battery reaches its discharge voltage, it is said to be "dead" and can no longer be used.
