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.
Guide to charging Sealed Lead Acid batteries
When an SLA battery is being discharged; the lead (Pb) on the negative plate and the lead dioxide (PbO2) on the positive plate are converted to lead sulphate (PbSO4). At the same time the sulphuric acid (H2SO4) is converted to water (H2O). In a normal charge, the chemical reaction is reversed. The lead sulphate and water are electro-chemically ...
