Material Safety Data Sheet (MSDS)
According to ISO 11014-2009
Report No.: DGC180409025KEA02 Date: Dec. 17, 2020 Page 9 of 10
Product Name: Lead-acid battery (2V/4V/6V/12V)
Hazardous decomposition products: Once batteries are breakage, split sulphuric acid should be
careful which is corrosive, nonflammable liquid (thermal decomposition at 338℃) and destroys organic
materials such as cardboard, wood, textiles and reacts with metals, producing hydrogen. Acrid or
harmful gas is emitted during fire.
Section 11 - Toxicological Information
Carcinogenicity: The International Agency for Research on Cancer (IARC) has classified “strong
inorganic acid mists containing sulfuric acid” as a category 1 carcinogen (inhalation), a substance that is
carcinogenic to humans. This classification does not apply to the liquid forms of sulfuric acid contained
within the battery. Misuse of the product, such as overcharging, may result in the generation of sulfuric
acid mist at high levels.
Section 12 - Ecological Information
This information is of relevance if the battery is broken and the ingredients are released to environment.
In order to avoid damage to the sewage system, the acid has to be neutralized by means of time or
sodium carbonate before disposal. Ecological damage is possible by change of pH. The electrolyte
solution reacts with water and organic substances, causing damage to flora and fauna. The electrolyte
may also contain soluble components of lead that can be toxic to aquatic environments. Leaking metals
will easily penetrate the soil, polluting groundwater, and then into the fish life, crops, the destruction of
the human living environment, an indirect threat to human health. More importantly, the contaminated
soil will be permanently lose its use value.
The waste batteries contain heavy metals can not be biodegradable and can accumulate in vivo.
Section 13 - Disposal Considerations
The nature of waste: Hazardous waste
Waste disposal methods: Dispose of batteries according to government regulations. Recommend sent
to a special recycling bins of used batteries.
Notes waste: Do not waste batteries and garbage mixed together, to be dealt with separately.
