CSB Energy Technology Co., Ltd. is a leading global manufacturer of valve-regulated lead-acid (VRLA) batteries. The company was established on November 28, 1986, formerly as Taiwan Kobe Battery Co., Ltd., entered a joint venture with Shin-Kobe Electric Machinery Co., Ltd. in 1987, and officially changed its name to CSB Energy Technology Co., Ltd. in May 2020. It currently employs more than 2,000 people, and its products are sold in more than 100 countries and regions.
The company's global headquarters is located at 11F, No. 150, Sec. 4, Chengde Rd., Shilin District, Taipei City 111052, Taiwan, China, and it has established CSB Energy Technology (Shanghai) Co., Ltd. in mainland China as its China headquarters, located at Room 2304, Youyou International Plaza, No. 76 Pujian Road, Shanghai; the Shenzhen branch is located at Room 209, 2nd Floor, Building A, Xincheng Plaza, No. 86 Puxia Road, Liuyue Community, Henggang Street, Longgang District, Shenzhen. Production bases are located in Taiwan, China, Vietnam, the Philippines, and mainland China, forming a multi-location manufacturing and supply system.
In terms of product range, the company has 142 models on sale, covering 20 series, with voltages spanning 2V cells, 6V, 12V, and 512V lithium battery cabinets; capacity-type products range from 4.5Ah to 1700Ah, and power-type products from 18W to 9000W (5 to 15 minute rate). The products use a valve-regulated sealed lead-acid (VRLA) design, achieving efficient gas recombination through absorbed glass mat (AGM) separators with a recombination rate of up to 99%, and feature a pure lead grid structure and proprietary formulation, offering maintenance-free, rechargeable, and leak-proof characteristics.
Product applications cover data center UPS, renewable energy, telecommunications, general-purpose, and electric mobility. The data center UPS segment addresses uninterruptible power supply needs for enterprise, cloud, hyperscale, multi-tenant, edge, and colocation services; the renewable energy segment is used for deep-cycle, long-duration discharge in residential, commercial and industrial, and utility-scale energy storage; the telecommunications segment is used for float long-duration backup in wired backbone stations, wireless macro cells, and wireless small cells; the general-purpose segment is used for daily applications such as emergency lighting, security, and medical equipment; the electric mobility segment is used for deep-cycle applications in personal mobility devices such as scooters, wheelchairs, and RVs.
In terms of technology and standards, the company's product model data cites standards including IEC 61056-1/2:2012, IEC 60896-21/22:2004, IEC 60254-1:2005 / IEC 60254-2:2008, IEC 61427, and UL1989 Recognized (MH14533), while Calor XHT-FT additionally cites UL 1973 Recognized (MH66728). Design life is stated under float standby at 25°C, covering 5 to 20 years, with some series marked with Eurobat (20°C) classifications. Charge voltage is stated at 25°C with float and equalizing ranges by battery or cell, for example 12V batteries at 13.5-13.8 Vdc float and 14.4-15.0 Vdc equalizing; nominal temperature is 25°C, discharge temperature range is -15°C to 50°C (some series -25°C to 50°C), and charge and storage temperature range is -15°C to 40°C.
