The components in Lead-Acid battery includes; stacked cells, immersed in a dilute solution of sulfuric acid (H 2 SO 4), as an electrolyte, as the positive electrode in each cells comprises of lead dioxide (PbO2), and the negative electrode is made up of a sponge lead.
The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO4– → PbSO4 + H+ + 2e– At the cathode: PbO2 + 3H+ + HSO4– + 2e– → PbSO4 + 2H2O Overall: Pb + PbO2 +2H2SO4 → 2PbSO4 + 2H2O
A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
Acid burns to the face and eyes comprise about 50% of injuries related to the use of lead acid batteries. The remaining injuries were mostly due to lifting or dropping batteries as they are quite heavy. Lead acid batteries are usually filled with an electrolyte solution containing sulphuric acid.
Full compliance requires: Proper documentation includes UN number, shipping name, class and packing group (no packing group for lead-acid batteries). In the case of vented lead acid batteries, the information is as followed: Proper packaging and containment during transportation of the batteries.
The usable life of a lead acid battery is typically approximately 5 years or 250–1000 charge-discharge cycles, depending on the depth of discharge . P. Kurzweil, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2023 The lead-acid battery is the most important low-cost car battery.

About the Lead Acid Battery
Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.

Red lead: understanding red lead in lead−acid batteries
The use of red lead in battery plates is not very well known to a large segment of the lead–acid battery industry. Historically, it was used in pasted and tubular positive plates in order to improve their formation time and enhance deep-cycle performance. Although the use of red lead has diminished over the last few decades, many companies are again considering the …
