Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
About Photovoltaic Energy StorageI have a lead Acid battery which is 12 volt 72AH. The load I applied to it is a fan of 12volt 9 amp. It only runs about an hour and slows down. As per my battery capacity it should run almost 7 to 8 hours. I have checked my …
