About Naradex
We are a professional backup AGM battery manufacturer, specializing in VRLA lead-acid batteries for UPS, telecom, data centers, and emergency power systems since 2006.
Our Story
Established in 2006, Naradex (Best Battery Tech Co., Ltd) started as a small battery factory and has grown into a middle-to-large scale manufacturer with over 400 employees. We specialize exclusively in backup AGM batteries — nothing else, just batteries done right.
In 2015, we invested approximately one million USD in advanced production equipment including fully automatic ball mill machines, mixing & pasting machines, curing ovens, and environmental facilities, significantly improving our production efficiency and battery quality.
Today, we produce 400,000 KVAH of batteries annually and export to more than 100 countries, serving as a reliable battery partner for UPS system integrators, telecom operators, and power utility companies worldwide.
