11. Toxicological Information
This information does not apply to the finished product “lead-acid battery”. This information only applies to its compounds in
case of a broken product. Different exposure limits exist on a national level.
11.1 Electrolyte (diluted sulphuric acid):
Sulphuric Acid is intensely corrosive to skin and mucous membranes; the inhalation of mists may cause damage to the
respiratory tract.
11.2 Lead and Lead compounds
Lead and its compounds used in a Lead Acid Battery may cause damage to the blood, nerves and kidneys when ingested. The
lead contained in the active material is classified as toxic for reproduction.
12. Ecological Information
This information does not apply to the finished product “lead-acid battery”. This information only applies to its compounds in
case of a broken product and the compounds are released to the environment.
12.1 Electrolyte (diluted sulphuric acid)
In order to avoid damage to the sewage system, the acid has to be neutralised by means of lime 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.
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 that Battery Lead Oxide in a concentration of 100 mg/l has no adverse effect on fish and daphnia. A
concentration of 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 H400/410 (Harmful to aquatic organisms,
may cause long-term adverse effects in the aquatic environment).
13. Recycling Information
Spent lead-acid batteries are subject to regulation of the EU Battery Directive (2006/66/EU) and its adoptions into national
legislation.
Spent Lead-Acid batteries (EWC 160601) are recycled in lead refineries (secondary lead smelters). The components of a spent
Lead-Acid battery are recycled or re-processed.
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.
For safety reasons and to simplify the collection and recycling or re-processing process, spent Lead-Acid batteries must not be
mixed with other batteries. Especially spent high energy batteries (such as Li-Ion batteries) have to be kept separate from spent
Lead-Acid 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.
