ESTL has comprehensive testing capabilities in the field of battery testing, a strong technical service team with one-on-one and efficient service, and a large battery testing experimental base operates 24 hours. ESTL has been authorized by many international organizations such as UL, IECEE, TÜV, KTC, KTR, JET, DGM, ITS, etc., providing battery customers with professional global certification, safety regulations, electromagnetic compatibility, energy efficiency, reliability testing, etc. One-stop service.

As the best power supply, the battery is widely used in mobile communication equipment, electronic digital products, power products, and medical and security fields. However, in recent years, global battery recalls have triggered concerns about the safety of battery products in various countries. At the same time, market surveillance agencies in various countries have increased the supervision of battery products, making domestic battery manufacturers face the challenge of improving product quality. Therefore, the testing, inspection and certification of battery products are becoming more and more important. ESTL provides national certification testing services for various battery products, helping the battery manufacturers to quickly seize the international market through the certification of national standards.
