Battery Testing




Testing Lab Intro

DET battery testing lab has been accredited with a CTF (Customer Testing Facilities Certificate) by TUV. We offer testing services not only for DLG’s products but also for other battery manufacturers who need to test batteries performance or apply for certain certificates. The tests range from basic performance tests to battery safety, abusing, durability and dynamic impact tests etc. Contact our testing staff if you need assistance on battery testing.
