Thus, fast charging of a lead–acid cell can be achieved without a loss of cycle-life, despite the fact that higher currents are forced into the cell. 1. Introduction The fast charging of a lead–acid battery, or indeed other secondary rechargeable batteries, is a key technology for electric vehicles.
Charging of lead–acid cell Discharging of a lead–acid cell The chemical reaction takes place at the electrodes during charging. On charge, the reactions are reversible. When cells reach the necessary charge and the electrodes are reconverted back to PbO 2 and Pb, the electrolyte's specific gravity rises as the sulfur concentration is enhanced.

Batteries of lead–acid are extensively used in diverse applications like automotive industries, telecommunications systems, hospitals, emergency lighting, power tools, alarm systems, material handling, railway air-conditioning and coach lighting, and so on.
Lead–acid batteries have issues with accelerated corrosion of the battery plates, faster self-discharge, rapid water loss, gas formation, and significant internal resistance variance.
Lead–acid batteries’ long-term sustainability is often questioned. Many have claimed that only the lead–acid battery has no future, but this is nothing new, and amid decades of predictions to the contrary, the lead–acid battery continues to dominate the global battery energy storage market.
