Section 10: Stability and reactivity
10.1 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.
10.2 Chemical Stability:
The battery and contents are stable under normal conditions.
10.3 Possibility of hazardous reactions:
Hazardous polymerization will not occur.
10.4 Conditions to avoid:
Overheating or overcharging the battery may results in acid mist and hydrogen
generation.
10.5 Incompatibility (materials to avoid):
Strong alkaline materials, conductive metals, organic solvents, spark or open flame.
10.6 Hazardous decomposition products:
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.
Section 11: Toxicological Information
11.1 Information on toxicological effects:
Our 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.

Inhalation
Under normal conditions of use, no health effects are expected.
Contents of an open battery can cause respiratory irritation.
Repeated and prolonged exposure
may cause irritation.
Skin
Under normal conditions of use, no health effects are expected.
No data available
Eye
Under normal conditions of use, no health effects are expected.
Exposure to dust may cause irritation.
No data available.
Ingestion
Under normal conditions of use, no health effects are expected. Lead
ingestion may cause abdominal pain, nausea, vomiting, diarrhea and
severe cramping.
No data available
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.
