Organic acid leaching followed by calcination process shows a facile and mild route in recovery of spent lead-acid battery with low-emission of hazardous gases, which are the most studied processes for the recovery of spent lead paste.
To recover a lead acid battery, charge it for around 10 to 12 hours. Then, measure the terminal of the battery. After that, check the voltage of each cell and identify any cells with a voltage lower than 2 volts.
Recycling lead from wasted lead acid batteries is related to not only the sustainable development of lead-acid battery industry, but also the reduction of the lead pollution to the environment.
The current efficiency is as high as 99.9% and the electrolytic lead recovery rate reaches up to 99.8%. In addition, the new recovery process avoids the emission of lead effluent by means of the recycling of the waste electrolyte. Therefore, it is a lead recovery process of low energy consumption and environmental friendliness.
For the recovery of lead from solution, although it can be achieved by cementation using iron powder, this method has the disadvantages of large iron powder entrainment and a low lead recovery ratio. In the case of electrowinning, the power consumption is often high.
The lead acid battery has been widely used in automobile, energy storage and many other fields and domination of global secondary battery market with sharing about 50% . Since the positive electrode and negative electrode active materials are composed of PbO 2 /PbSO 4 and Pb/PbSO 4, lead is the most important raw material of lead acid batteries.

BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage …
