18650 Battery Compliance

You can rest assured that all of our products are provided to the highest standards, as we hold MSDS, UN38.3 and batch test reports for all batteries that we sell.

All batteries we supply are stamped inline with the EU Battery Directive, using electric printing technology that permanently binds to the battery surface. We also carry out in-house testing on batteries and have devised an innovative platform that provides you with full traceability - you can check out the EXOCELL website to conduct a traceability test on your batteries. 

What is required to ensure a compliant battery? 

Lithium-Ion cells are perfectly legal to import and sell, however, they do require specification data on them to fully comply. This information needs to be indelible and thus can’t be simply a sticker, but must be permanently printed and visible on the outside of the battery. The following information must be legible;

  • Battery capacity
  • Chemistry of the battery
  • Positive and Negative +/- (polarity) Symbols
  • The WEEE Symbol.

Printing on cylindrical batteries comes with many challenges, especially as you cannot use a  contact printing method. To mitigate any risk, we use a special printing machine that permanently binds the ink to the surface using electric. This machine was a significant investment for Fogstar but was required to ensure a compliant supply of batteries to our customers. 

The battery directive also calls for two other elements;

  • Battery traceability
  • In-house testing.

Here at Fogstar, we have always tested the legitimacy of our cells. When it comes to traceability, we developed a testing platform called EXOCELL. This system enables us to generate a unique 4 digit code for all of our batteries, we then display the test results to anyone that enters the code on the website, this system provides full visibility for all in-house testing and traceability.

It’s probably worth noting that batteries do not require CE marking and do not have to have a certificate of conformity - mainly due to the fact that there is no circuitry in a battery. A CE marking is an administrative marking that indicates conformity with health and safety, and environmental protection standards for products sold within the EEA (European Economic Area). Batteries can still pass a CE test, but they do not require one by law.
