What is a Lead-Acid Battery? A lead-acid battery is a type of rechargeable battery used in many common applications such as starting an automobile engine. It is called a “lead-acid” battery because the two primary components that allow the battery to charge and discharge electrical current are lead and acid (in most case, sulfuric acid).

Today's innovative lead acid batteries are key to a cleaner, greener future and provide nearly 45% of the world's rechargeable power. They're also the most environmentally sustainable battery technology and a stellar example of a circular economy. Batteries Used?
Nearly all lead batteries are made of recycled lead and plastic, and all are recycled at the end of their service lives. The initial process begins with the manufacturing of grids from an alloy of lead mixed with a small percentage of other metals. The grids conduct the current and provide a structure for the active material to adhere.
The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state. In the charging process we have to pass a charging current through the cell in the opposite direction to that of the discharging current.
