Why don''t lead acid batteries last forever?
When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely. Some sulfates crystalize and remain attached to the plates, which means over time, less sulfates are available to be part of the chemical reaction needed for the battery ...
