New Energy Sources WhatsAppExplore what causes corrosion, shedding, electrical short, sulfation, dry-out, acid stratification and surface charge. A lead acid battery goes through three life phases: formatting, peak and decline (Figure 1) the formatting phase, the plates are in a sponge-like condition surrounded by liquid electrolyte.
New Energy Sources WhatsAppLead-acid batteries should never be allowed to remain for a long period in a discharged state because lead sulfate could harden and permanently clog the pores of the electrodes. Before storing it for a long time the battery should be completely charged, then the electrolyte should be drained so that the battery is stored dry.
New Energy Sources WhatsAppEach cell produces 2 V, so six cells are connected in series to produce a 12-V car battery. Lead acid batteries are heavy and contain a caustic liquid electrolyte, but are often still the battery of choice because of their high current density. The lead acid battery in your automobile consists of six cells connected in series to give 12 V.
