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.
Battery leakage FAQs: how to handle leaking batteries safely
Battery leakage occurs when chemicals escape from a battery, posing risks to humans and devices. Lead-acid batteries can leak sulfuric acid, while lithium batteries use safer materials and sealed designs to prevent leaks. Understanding battery types and handling
