What hazardous substances do batteries need to be controlled?

How to deal with battery labeling requirements?

◉   Service Background

Batteries may contain mercury, lead, cadmium, other heavy metals and acid or alkali electrolyte solutions. If they are not properly handled, they will cause varying degrees of harm to the human body and the ecological environment. Therefore, the collection and post-processing of used batteries are very important. The European Parliament and the Council of the European Union issued Directive 2006/66/EC about Batteries and Accumulators and Waste Batteries on September 26, 2006. The Directive relates to the restrictions of hazardous substances in batteries, and the relevant policies for the recycling and recycling of used batteries. On December 10, 2013, the European Union announced the revised directive 2013/56/EU of 2006/66/EC. The new battery directive revised several exemptions. The EU battery directive includes battery hazardous substances limit requirements, labeling requirements and recycling rate requirements.

On April 30, 2021, the State Administration for Market Regulation and the Standardization Administration of China issued the national mandatory standard GB 24427-2021 Content limitation of mercury, cadmium and lead for zinc anode primary battery, which replaced GB 24427-2009 Limitation of mercury, cadmium and lead contents for alkaline and non-alkaline zinc manganese dioxide batteries and GB 24428-2009 Limitation of mercury content for zinc silver oxide, zinc oxygen and zinc manganese dioxide button batteries. The new standard will be officially implemented on November 1, 2021.

In 1996, the United States promulgated the Public Law 104-142: Mercury-Containing and Rechargeable Battery Management Act, which came into effect on May 13, 1996, requiring battery manufacturers to use a uniform prescribed label. Detailed regulations have also been made on the transportation, collection and storage of batteries and waste batteries, and manufacturers are encouraged to invest in battery recycling and proper disposal of waste batteries, and to encourage research and production of new batteries.

EU Battery Directive:

Member States shall prohibit the placing on the market of:

(a) all batteries or accumulators, whether or not incorporated into appliances, that contain more than 0,0005 % of mercury by weight; and

(b) portable batteries or accumulators, including those incorporated into appliances, that contain more than 0,002 % of cadmium by weight.

Member States shall ensure that all batteries, accumulators and battery packs are appropriately marked with the symbol

Batteries, accumulators and button cells containing more than 0,0005 % mercury, more than 0,002 % cadmium or more than 0,004 % lead, shall be marked with the chemical symbol for the metal concerned: Hg, Cd or Pb. The symbol indicating the heavy metal content shall be printed beneath the symbol indicating ‘separate collection’ for all batteries and accumulators shall be the crossed-out wheeled bin and shall cover an area of at least one-quarter the size of that symbol.

China battery mandatory standard:

According to the labeling requirements in GB/T 8897.1; Hazardous substances can be marked as "mercury-free", "cadmium-free" and "lead-free" according to the content of mercury, cadmium and lead.

US battery requirements:

Battery manufacturers must use the uniformly prescribed repeating cycle symbol for the marking of batteries and battery packs. Different types of batteries must also be marked with different words, such as lead-acid batteries, must have the words "Pb" or "LEAD", "RETURN", "RECYCLE", and if the regulated battery is sealed, it must also have the words “BATTERY MUST BE RECYCLED”.

◉ Frequently asked questions

1. How long does the test take?

Normal 4 working days. If you need faster, please contact our business or customer service.

2. Whether the content limit of hazardous substances in batteries is based on homogeneous material evaluation or article evaluation?

According to the entire battery evaluation, conventional battery products are divided into homogeneous material tests, and the test results are converted into the content of finished battery products.

3. If the battery test is RoHS2.0 qualified, is the battery directive also qualified?

Not necessarily, the EU RoHS2.0 control scope does not include batteries, and the EU RoHS2.0 test of electronic products needs to remove the battery. The substance limit controlled by the battery directive is lower than that of RoHS. Even if RoHS2.0 is qualified, the battery directive may not be qualified.
