A fully charged battery contains pure lead (anode) and lead dioxide (cathode). As the battery discharges the lead sulfate forms in an amorphous compound on the plates and the reaction is easily reversed. If any battery sits long in a discharges state, the amorphous lead sulfate will crystallize and become hard to recharge. Many claims have been made that equalization breaks up sulfate crystals but that has not been proved scientifically.



Driving a coach regularly stirs the electrolytes quite well, equalization is not necessary. If you dry camp for long periods in one place, or store your coach for long periods the equalization will help revive your batteries, or you could just drive 60 mph on I-57 in Illinois, I-10 in Louisiana or I-65 in Indiana. If you choose to equalize you will loose significant distilled water and it should be replaced immediately. If any part of the battery's plates are exposed to the air. the battery will suffer major irreparable damage.

Submarines drive through and on top of the ocean but they still equalize their batteries once a quarter.
