With the latest advanced design of Oxygen Combination, We have produced a new generation of Valve - regulated Lead Acid batteries based on a long history of more than 18 years in research and development. Since 1991,We have been specialized in designing and producing VRLA batteries with Japanese AGM technology. All of our VRLA batteries meet the technology requirement stipulated in both JISC8702 and IEC60876-2. We introduced Y & M technology ( a special technology in battery plates ) from Toyama University in Japan. Based on different designs in technologies to be suitable for different applications, our VRLA batteries can be classified NP, NPC, NPL, NPG, NPM and NPH series.
