Lead-Acid Battery Basics
Lead-Acid Battery Cells and Discharging. 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.

High temperatures, in particular, can have a negative impact on battery performance and life. Lead-acid and NiCd batteries both exhibit a negative on-charge temperature coefficient. That means that as the battery temperature rises, the battery terminal voltage decreases if the charging current is kept constant.
