Lead-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.
A battery is an energy storage device. Here the lead–acid battery''s working theory is discussed. It''s rare in the world of rechargeable or secondary batteries. The positive plate contains lead dioxide (PbO 2), the negative plate contains sponge lead (Pb), and the electrolyte is dilute sulfuric acid (H 2 SO 4).).
