Principles of lead-acid battery. Lead-acid batteries use a lead dioxide (PbO 2) positive electrode, a lead (Pb) negative electrode, and dilute sulfuric acid (H 2SO 4) electrolyte (with a specific gravity of about 1.30 and a concentration of about 40%).

In all cases the positive electrode is the same as in a conventional lead–acid battery. Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles.
Storing a battery acid outside of a battery is a challenge both in regard to safety and purity.
