CSB Energy Technology Co., Ltd. (CSB) was founded in 1986 and has always focused on the development and production of valve-regulated lead-acid (VRLA) batteries, with a market presence spanning more than 100 countries and regions worldwide. Based on the VRLA-AGM technology platform, its product line currently covers 20 series with a total of 142 active models. Voltage classes range from 2V cells, 6V, and 12V all the way to 512V lithium battery cabinets; capacity types meet requirements from 4.5Ah to 1700Ah, while high-rate types cover 18W to 9000W (5–15 minute rate), providing suitable options for both everyday standby and high-power short-duration discharge.

In terms of technical approach, CSB's VRLA products achieve efficient gas recombination through absorptive glass mat (AGM) separators, with recombination efficiency of up to 99%, combined with pure lead grid construction and proprietary formulations, resulting in maintenance-free, rechargeable, and leak-proof characteristics. According to model documentation, referenced standards include IEC 61056-1/2:2012, IEC 60896-21/22:2004, IEC 60254-1:2005, IEC 60254-2:2008, IEC 61427, and UL1989 Recognized (MH14533), among others; Calor XHT-FT additionally carries UL 1973 Recognized (MH66728). Design life is stated under 25°C float standby conditions, ranging from 5 to 20 years, with some series also indicating Eurobat (20°C) classifications.

For data center UPS applications, CSB offers multiple product lines: the HR series is a high-rate discharge pure lead battery suitable for lower-output UPS and backup scenarios requiring rapid discharge; the HRL series is a long-life high-rate pure lead battery that meets high-power data center and UPS load requirements; XHRL and its front-terminal version XHRL-FT further enhance high-rate output capability; XPL and XPL-FT address long-duration backup with high-capacity pure lead requirements; the UPS series is specifically designed for uninterruptible power supplies using high-power pure lead batteries; the XHT series is suited for mission-critical power in harsh environments. The PowerBox series is presented as a 512V lithium iron phosphate (LiFePO4) battery cabinet, with a maximum continuous rack discharge power of 300kW, nominal capacity of 140Ah, nominal energy of 71.68kWh, and communication interfaces supporting RS485, CAN, Ethernet, and dry contacts.

In telecommunications, the MSJ, MSV, and MU series are all 2V high-capacity long-life VRLA-AGM batteries; the MSJ offers float standby service life of up to 20 years, while the MU further extends capacity beyond the MSV/MSJ; the TPL series is a front-terminal long-life pure lead battery suitable for multi-hour backup in broadband applications; the XTV series can be used in indoor and outdoor telecom broadband scenarios. In renewable energy, the RE series is a pure lead carbon high-capacity battery with excellent cycle life and service life, available in 2V and 2V modular forms; XTV-WT is designed for the harsh environments of wind power generation. General-purpose applications are covered by the GP series for security, emergency lighting, and medical equipment, with the GPL series being its extended-life version. For electric mobility, the EVX series is a durable deep-cycle pure lead battery, while the EVH series builds on the EVX to enhance cycle life and durability.

Overall, CSB uses VRLA-AGM as its technological foundation and, through differentiated approaches such as pure lead grids, front-terminal structures, high-temperature designs, and lithium solutions, has built a product matrix covering data center UPS, telecommunications, renewable energy, general-purpose, and electric mobility applications. Charging voltages are specified at 25°C per battery or cell, for example, 12V batteries at 13.5-13.8 Vdc float and 14.4-15.0 Vdc equalize; temperature ranges are nominal 25°C, with discharge from -15°C to 50°C (some series -25°C to 50°C), and charging and storage from -15°C to 40°C, providing a clear basis for selection and operation across different scenarios.
