SECTION 3: Hazard Identification

No hazards occur during the normal operation of a Lead Acid Battery as it is described in the instructions for use that are provided with the Battery. Lead acid Batteries have three significant characteristics:

  • They contain an electrolyte which contains diluted sulphuric acid. Sulphuric acid may cause severe chemical burns.
  • During the charging process or during operation they might develop hydrogen gas and oxygen, which under certain circumstances may result in an explosive mixture.
  • They can contain a considerable amount of energy, which may be a source of high electrical current and a severe electrical shock in the event of a short circuit.

The Batteries have to be marked with the symbols listed under section15.

SECTION 4: First Aid Measures

1. Electrolyte (diluted sulphuric acid): sulphuric acid acts corrosively and damages skin



- Rinse the affected area under running water for 15 minutes
- Remove contaminated clothing
- If irritation, seek advise of medical attention

- Do not induce vomiting
- Drink 8 oz. of water or milk
- If difficulty in breathing occurs, try moving under fresh air and have CPR when necessary
- Seek medical attention immediately

2. Lead compounds: lead compounds are classified as toxic for reproduction (if swallowed)

SECTION 5: Fir-Fighting Measures

Hydrogen Flash point: -259°C    Hydrogen Autoignition point: 580°C
Hydrogen Flammable Limits in Air (% by Volume):
Lower Explosion Limit (LEL) : 4.1; Upper Explosion Limit (UEL) : 74.2
Unusual Fire and Explosion Hazards: Hydrogen and Oxygen gases are produced in cells during normal battery operation and expel into air through vent caps.
Extinguishing Media: Foam, CO2 or dry powder extinguishing agents
Special Firefighter Procedures: Use Positive Pressure, self-contained breathing apparatus.

SECTION 6: Accidental Release Measures

The information is of relevance only if the battery is broken and the ingredients are released.
In the case of spillage, try neutralizing exposed battery parts with soda ash or sodium bicarbonate until fizzing stops; and using sand or bonding agent to absorb split acid. Provide adequate ventilation because heat, carbon dioxide and hydrogen gas may be given off during neutralization. Collect residue in a suitable container and place the broken battery in a heavy-duty plastic bag or other non-metallic container. Properly recycle all battery residue and parts based on official local regulations.

SECTION 7: Handling and Storage

Store under roof in cool ambiance charged lead acid batteries do not freeze up to -50°C; Prevent short circuits.. If batteries have to be stored, it is imperative that the instructions for use are observed.

SECTION 8: Exposure Controls and Personal Protection

Engineering Controls:
Store batteries with adequate ventilation. Room ventilation is also required for batteries utilized for standby power generation. Never recharge batteries in an unventilated, enclosed space.

Personal Protective Equipments:
During installation, normal conditions of use or in the event of battery breakage, no exposure to lead and lead containing battery paste. Exposure to sulphuric acid and acid mist might occur during charge.               

Eye Protection = Chemical goggles, safety glasses with side shields and or a full-face shield.
Protective gloves = Rubber, PVC or neoprene
Respiratory Protection = NIOSH approved acid mist/organic vapor respirator, if OSHA PEL is exceeded.
Other Protective Equipment = Acid resistant apron or clothes.

Work Practices:
Use standard lead-acid battery practices. Do not wear metallic jewelry when working with batteries. Use non-conductive tools only. Discharge static electricity prior to working on a battery. Maintain eyewash, fire extinguisher and emergency communication device in the work area.

Lead and Lead compounds used in Lead Acid batteries are poorly soluble in water; Lead can be dissolved in an acidic or alkaline environment only.

SECTION 10: Stability and Reactivity

STABILITY: The battery and its contents are stable but need to avoid several situations during usage, such as overheating, overcharging which results in acid mist and hydrogen generation. Hydrogen gas may be generated from overcharging, fire or at very high temperatures, especially CO, CO2 and Sulfur Oxides may emit during in fire. Hence, some materials also should be avoid placing together with batteries, for example, strong alkaline materials, organic solvents, or conductive metals caused sparks or open flame.

Reactivity: 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.

SECTION 11: Toxicological Information

PILOT 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 fauna. The electrolyte may also contain soluble components of lead that can be toxic to aquatic environments.

12.2 Lead and Lead compounds
Chemical and physical treatment is required for the elimination from water. Waste water containing lead must not be disposed of in an untreated condition. The former classification of Lead compounds as toxic for the aquatic environment R50/53 had been triggered from test results generated in the 80’s for soluble Lead compounds (Lead Acetate). The hardly soluble Lead compounds such as Battery Lead Oxide were not tested at this time. Tests on Battery Lead Oxide were carried out in 2001 and 2005. The respective test results conclude that Battery Lead Oxide is not toxic for the environment, neither R50 nor R50/53 nor R51/53. From this it follows that the general classification for Lead compounds (R50/53) does not apply to Battery Lead Oxide. As the result of this the Risk Phrase R52/53 (Harmful to aquatic organisms, may cause long term adverse effects in the aquatic environment) applies to Battery Lead Oxide.

Effects of Battery Lead Oxide in the aquatic environment:
Toxicity for fish:              96 h LC 50 > 100 mg/l
Toxicity for daphnia:      48 h EC 50 > 100 mg/l
Toxicity for alga:             72 h IC 50 > 10 mg/l

The results demonstrate these Battery Lead Oxide compounds in a concentration of 100 mg/l have no adverse effect on fish and daphnia. A concentration of these Battery Lead Oxide of 10 mg/l has no adverse effect on the rate of growth and the biomass. For the classification according to Directive 67/548/EEC the most sensitive adverse effect has to be considered. As a result of the toxicity for alga at > 10 mg/l Battery Lead Oxide has to be classified according to the R-Phrases 52/53 (Harmful to aquatic organisms, may cause long term adverse effects in the aquatic environment).

SECTION 13: Disposal Considerations

Spent lead acid batteries (EWC 160601) are subject to regulation of the EU Battery Directive and its adoptions into national legislation on the composition and end of life management of batteries.

Spent Lead Acid batteries are recycled in lead refineries (secondary lead smelters). The components of a spent Lead Acid battery are recycled or reprocessed.

At the points of sale, the manufacturers and importers of batteries, respectively the metal dealers take back spent batteries, and render them to the secondary lead smelters for processing.

To simplify the collection and recycling or reprocessing process, spent Lead Acid batteries must not be mixed with other batteries. By no means may the electrolyte (diluted sulphuric acid) be emptied in an inexpert manner. This process is to be carried out by the processing companies only.

SECTION 14: Transport Information

All PILOT batteries are identified as “Battery, Electric Storage, Wet, Nonspillable” when transported by air, sea or by land transportation. The battery(s) must be identified as above on the Bill of Lading and properly packaged with their terminals protected from short circuit. NA or UN numbers do not apply. PILOT  battery(s) warning label identifies each battery as NONSPILLABLE.

PILOT seal lead-acid batteries are classified as “Nonspillable” for the purpose of transportation by DOT, and IATA/ICAO as result of passing the Vibration and Pressure Differential Test described in DOT [
49 CFR 173.159 (f)] and IATA/ICAO [Special Provision A67].PILOT seal lead-acid batteries can be safely transported on deck, or under deck stored on either a passenger or cargo vessel as result of passing the Vibration and Pressure Differential Tests as described in the IMDG regulations(Special Article 238).

To transport these batteries as “non-spillable” they must be shipped in a condition that would protect them from short-circuits and be securely packaged so as to withstand conditions normal to transportation by a consumer, in or out of a device, they are unregulated thus requiring no additional special handling or packaging.

For all modes of transportation, each battery and outer package is labeled “NON-SPILLABLE per
49 CFR 173.159(f) and 49 CFR 173.159a. If you repackage our batteries either as batteries or as a component of another product you must label the outer package “NON-SPILLABLEper 49 CFR 173.159(f) and 49 CFR 173.159a..


SECTION 15: Regulatory Information

In accordance with EU Battery Directive and the respective national legislation, Lead Acid batteries have to be marked by a crossed out dust bin with the chemical symbol for lead shown below, together with the ISO return/recycling symbol. If other countries or the region have time in addition the stipulation must observe
