Product details

HR12120W comes from CSB's HR series and is a high-rate discharge pure lead battery; its product type is a 12V top-terminal valve-regulated sealed lead-acid battery, and the officially listed application is data center UPS. This product line is positioned as a high-rate discharge pure lead battery series, mainly targeting lower-output UPS and backup power scenarios requiring rapid discharge. The battery uses a valve-regulated sealed lead-acid construction with absorbed glass mat technology, can achieve 99% gas recombination efficiency, and is maintenance-free; the pure lead construction and proprietary element formulation make it suitable for high-rate UPS and float standby power supplies. Electrical specifications: at 25°C and 1.67 VPC, the 5-minute rate power is 232.17 W/cell, and the 15-minute rate power is 123 W/cell; voltage is 12 Vdc, and nominal capacity is listed as 120W @15min-rate (1.67 VPC @25°C). Current parameters: maximum charge current 12 A, maximum discharge current 225 A, short-circuit current 928 A, and internal resistance 8.2 mΩ. At 25°C, equalization voltage is 14.4 to 15.0 Vdc/battery, and float voltage is 13.5 to 13.8 Vdc/battery. Mechanical and physical: dimensions are length 166±2.0 mm, width 125±1.5 mm, height 175±2.0 mm; weight is 10.2 kg (20.48 lb). The case is ABS (UL 94-HB), and a flame-retardant (94-V0) version is also available when required. Terminal specification is I1-Thread lead alloy recessed terminal to accept M5 bolt; terminal torque is 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. Temperature conditions: nominal temperature 25°C; discharge range -15°C to 50°C; charge and storage range -15°C to 40°C. In float standby applications at 25°C, design life can reach 5 years; Eurobat (20°C) standard commercial life is 3 to 5 years. Self-discharge is less than 10% after 90 days of standing; at 25°C, storage is up to 6 months, and the battery should be fully charged before use; if storage temperature exceeds 25°C, charge earlier. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533).
