Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment caused by factory or design defects, excessive gas generation, or physical damage to the battery.
Lead–acid battery-recycling sites have themselves become a source of lead pollution, and by 1992, the EPA had selected 29 such sites for its Superfund clean-up, with 22 on its National Priority List. [39] An effective pollution control system is a necessity to prevent lead emission.
Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2).
Big Red — Made by Bleego (a parody of Mego), this water sprinkler toy depicts a Viking figure (complete with stereotypical horned Viking helmet) that spins around and sprays red liquid from its horns — liquid that is revealed to be hazardous, as evidenced by the thick utility gloves included to clean up the resulting mess.

BATTERY ACID, SEAWATER, AND CHLORINE There is much debate about what happens when "battery acid used in lead storage batteries is mixed with seawater." Some claim that chlorine gas (Cl2) is formed, others claim that hydrogen chloride gas (HCl) is formed, and others claim that neither gas is formed. The confusion lies in the phraseology.
Students of Franklin Elementary School harvested and ate vegetables grown near the ESB, Inc. Exide lead-acid battery factory. From 1920 until 1978, the Electric Storage Battery Company (later ESB, Inc.) operated a lead-acid battery factory on forty acres of land in Crescentville at the intersection of Adams Avenue and Rising Sun Avenue.

An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.

The largest use of lead in the early 21st century is in lead–acid batteries. The lead in batteries undergoes no direct contact with humans, so there are fewer toxicity concerns. [r] People who work in lead battery production or recycling plants may be exposed to lead dust and inhale it. [237]
