Lithium-ion battery certification

Lithium-ion battery certification

With the popularity of portable electronic devices, the efficiency reliability of batteries have become more more important. We are ready to provide an efficient testing certification service to verify compliance with related global battery requirements including UL, IEC, etc., make full use of any previous or concurrent UL assessment tests based on UL1642 UL2054.


For portable electronic products Safety requirements for lithium-ion batteries battery packs" GB 31241-2014

·  The stard will be enforced on August 1, 2015;

·  After the stard is implemented, all lithium battery products must meet the GB31241 stard;

·  After the new version of the national stard is enforced, it is expected to be subject to stricter stricter supervision. National sampling, provincial sampling, local sampling will adopt the new version of the national stard requirements in the new sampling plan.
