With the participation of many large-scale projects, such as the Three Gorges Project, Shanghai and Guangzhou subway project, Tianwan Nuclear Power Plant, CARR (China advanced public Reactor) project, electric power engineering, natural gas projects, as well as the countless tender, through active cooperation with these important customers, Hoppecke has expanded its business scope to all regions except Tibet. Hoppecke Shanghai Co., Ltd. is located in Shanghai, the leading Asia-Pacific economies slowly into the sky dragon, Hoppecke Power System (Shanghai) Co., Ltd. is a major battery products and technology services provider. UPS is connected to the mains due to long-term, high-quality power supply, power outages are rare use of the environment, the battery will be long-term in a floating charge state, a long time will cause the battery to chemical energy and electrical energy into each activity decreased, accelerated aging shorten life. Thus, generally every 2 to 3 months to be completely discharged once, discharge time can be determined based on the battery capacity and load size. After a full load discharge is completed, according to the provisions of more than 8 hours to recharge. Hoppecke Battery Features: 10-year design life of absorption glass mat technology in line with the gas efficiency of up to 99%, with a maintenance-free electrolyte function 3 year warranty (see DynaSTy warranty card, 41-9026) patented low-calcium alloy design, with the lowest calcium content, the maximum reduction in the growth of the grid, the gas generated in the industrial field, extending the battery life of every single cell is equipped with a patented and UL flame exhaust valve the battery safer and have a longer life having a consistent design recombination, thermal runaway protection against gas generation and flame retardant characteristics, consistent with Bellcore 4228 flame retardant polypropylene (PP) tank lid, in line with UL1778 unique fixing holes in plate coating paste technology, the active substance in the grid evenly TianTu sides, so that each single cell of the grid has a consistency, increasing the battery capacity, but also protects the plate consistency
