SECTION 10: Stability and Reactivity
Stability: The battery and contents are stable under normal conditions.
Conditions to avoid: Overheating or overcharging the battery may results in acid mist and hydrogen
generation.
Incompatibility (materials to avoid): Strong alkaline materials, conductive metals, organic solvents, spark or
open flame.
Hazardous byproducts: Hydrogen gas may be generated in an overcharged condition, in fire or at very
high temperatures. In fire, may emit CO, CO2 and Sulfur Oxides.
Hazardous polymerization will not occur
Reactivity: Broken batteries may result in small amounts of spilled electrolyte. Electrolyte is a corrosive,
nonflammable liquid. Electrolyte can destroy organic materials such as cardboard, wood, textiles.
Electrolyte may produce hydrogen as a reaction with some metals.
SECTION 11: Toxicological Information
CSB VRLA batteries are sealed, recombinant design that require no water replacement throughout their
service life, thus no contact is made with the battery’s internal components or chemical hazards. Under
normal use and handling, these batteries do not emit regulated or hazardous substances.

Carcinogenicity: The International Agency on Cancer (IARCC) 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.
12.1 Electrolyte (diluted sulphuric acid)
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
