The product range includes portable sealed secondary battery cells and batteries (sets) with alkaline or non-acidic electrolytes

Test standard IEC 62133 Secondary single cells and batteries (sets) containing alkaline or non-acidic electrolytes: Safety requirements for portable sealed secondary single cells and batteries (sets) used in portable equipment.

Battery CE Testing and Certification CE certification is a safety mark certification, regarded as a passport for manufacturers to open and enter the European market. Products bearing the CE mark can be sold in all European member states without having to meet the requirements of each member state, thus achieving free circulation of goods within the EU member states. Products affixed with the CE mark comply with the main requirements stipulated in relevant European directives and serve to confirm that the product has passed the corresponding conformity assessment procedures and/or the manufacturer's declaration of conformity. However, the CE mark affixed on batteries cannot be understood in this way.

The main factors affecting the safety performance of lithium-ion batteries include: the thermal stability of electrode materials, the thermal stability of electrolyte components, the ratio of positive and negative electrode materials, and the battery structure. Structurally, lithium-ion batteries can be divided into three parts: the cell, auxiliary components such as the protection circuit, and the battery case. The safety of the battery mainly depends on the cell, and the main reason for affixing the CE mark to the battery is that the electronic components and printed circuit boards (PCB) in the auxiliary components need to meet the requirements of the Electromagnetic Compatibility Directive (EMCD). However, in fact, the electromagnetic radiation generated by these auxiliary components in the battery is quite small and can basically meet the requirements of EMCD. Therefore, affixing the CE mark to the battery only indicates that the auxiliary components in the battery meet the requirements of EMCD, but it does not mean that the battery meets the relevant safety requirements.

However, electrical products entering the EU (such as mobile phones, electric toys, power tools, etc.) must meet the requirements of the EU's New Approach directives and bear the CE marking. Batteries, as accessories for many end products (such as mobile phones, electric toys, etc.), require their safety to be considered in conjunction with these end products. Therefore, many customers of end products, out of concern for the safety of their own products, require that their components also bear the CE marking, so that their products can better meet the requirements of relevant directives.

Therefore, if the battery products of export enterprises can meet the requirements of the EMCD directive and bear the CE mark, it will enhance their competitiveness in the market and secure a larger market share for the enterprises.
