Lead–acid batteries, invented by a French physicist, Gaston Plante, in 1859, were the first of their kind of secondary batteries in the world. The battery consists of two electrodes: the negative terminal, made of porous lead, and the positive terminal, made of lead oxide, and dilute sulphuric acid as the electrolyte.
Batteries of course are still allowed to contain lead; anything that is not permanently attached to them is not. The cost is close to the same in that the tin plating is much thinner. Corrosion testing has been conducted, and while lead is still superior, tin also performs well.
The remainder of this paper outlines the considerations that should be taken when disassembling a battery in order to produce test results that are indicative of the true operating state of the battery. Before a battery is disassembled, precautions must be taken to ensure the safety of any handlers during the disassembly process.
Regarding the treatment of hazardous waste, lead-acid batteries are the most damaging waste fraction. Phasing out lead-acid batteries for lithium-ion is currently too expensive to be feasible in the unregulated sector, and the capacity of governments to enforce such a measure is limited.
This not only extends the process chain, but also reduces the purity of the recovered cathode materials .Thus, battery cells should be disassembled down to the individual electrodes to achieve a pure separation as well as efficient collection of the active materials , as shown in Figure 4 (direct recycling with route B).
Disassembly tests were executed with the demonstrator. Findings proved that semi-automated disassembly of battery systems is feasible. They have developed a concept, i.e., a workstation for more flexibility, productivity, and safety in the disassembly of LIBs, at the module level.

Reasons for maintenance free lead-acid batteries
Maintenance free battery means that it is not required to be overhauled and maintained from the time of delivery to the time when it is in the hands of users until the end of its service life. The maintenance free battery is a sealed single battery and cannot be disassembled. What are the reasons for maintenance free lead-acid batteries?

How to Recondition Lead Acid Batteries
A lead acid battery typically consists of several cells, each containing a positive and negative plate. These plates are submerged in an electrolyte solution, which is typically a mixture of sulfuric acid and water. The plates are made of lead, while the electrolyte is a conductive solution that allows electrons to flow between the plates. The Chemistry Behind …

Lead–Acid Batteries
A lead–acid battery cannot remain at the peak voltage for more than 48 h or it will sustain damage. The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V. This stage of charging is also called "absorption," "taper charging," or trickle charging. In this mode …
