Product details

Within the CSB product line, the HR12120W belongs to the HR series of high-rate discharge pure lead batteries. It is a 12V top-terminal valve-regulated sealed lead-acid battery, with the official designated application being data center uninterruptible power supplies. This series is specifically designed for lower-output UPS systems and backup scenarios requiring rapid discharge, positioned as a high-rate discharge pure lead battery. This battery combines valve-regulated sealed lead-acid construction with absorbed glass mat technology, achieving gas recombination efficiency of up to 99%, offering maintenance-free characteristics, and, by virtue of its pure lead construction and proprietary element formulation, is suitable for high-rate UPS and float standby power applications. In terms of electrical specifications, the HR12120W has a voltage of 12 Vdc and a nominal capacity of 120W @15min-rate (1.67 VPC @25°C). Its 5-minute rate power is 232.17 W/cell, and its 15-minute rate power is 123 W/cell (both at 1.67 VPC @25°C). The maximum charging current is 12 A, the maximum discharge current is 225 A, the short-circuit current reaches 928 A, and the internal resistance is 8.2 mΩ. The float charging voltage range is 13.5 to 13.8 Vdc/battery (25°C), while the equalization charging voltage is 14.4 to 15.0 Vdc/battery (25°C). Regarding mechanical construction, the battery terminal uses an I1-Thread lead alloy recessed terminal to accept M5 bolt, with terminal torque of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version can also be provided upon request. The weight is 10.2 kg (20.48 lb), and the dimensions are length 166±2.0 mm, width 125±1.5 mm, and height 175±2.0 mm. Regarding operating temperature, the nominal temperature is 25°C, the allowable discharge range is -15°C to 50°C, and the charging and storage temperature range is -15°C to 40°C. Under 25°C float standby conditions, the design life can reach 5 years; according to the Eurobat (20°C) standard, the commercial life is 3 to 5 years. For self-discharge, it is less than 10% after 90 days, and it can be stored for up to 6 months at 25°C; it must be fully charged before use. If the storage temperature exceeds 25°C, charging is required earlier. This product is manufactured in accordance with IEC 61056-1/2:2012 and has obtained UL1989 Recognized (MH14533).
