Product details

The CSB HR1290W belongs to the HR series and is a 12V valve-regulated sealed lead-acid battery. The HR series is a pure lead high-rate discharge battery series, mainly targeting UPS and standby applications with lower output power requirements that require rapid discharge. In terms of construction, the battery utilizes a valve-regulated sealed lead-acid design and Absorbent Glass Mat (AGM) technology, achieving gas recombination efficiency of up to 99%, and combines a pure lead construction with a proprietary element formulation, making it suitable for high-rate UPS and float standby power applications. In terms of electrical specifications, the HR1290W has a voltage of 12 Vdc and a 15-minute rate nominal capacity of 90W; the 5-minute rate power reaches 179 W/cell, while the 15-minute rate power is 90.0 W/cell. The maximum charging current is 9.00 A, the maximum discharge current is 300 A, the short-circuit current reaches 836 A, and the internal resistance is 9.9 mΩ. At 25°C, the float charging voltage ranges from 13.5 to 13.8 Vdc/battery, and the equalization charging voltage ranges from 14.4 to 15.0 Vdc/battery. In terms of dimensions and weight, the battery is 181.0±2.0 mm long, 76.2±2.0 mm wide, and 167.0±2.0 mm high, weighing 6.60 Kg. The terminal is I1 type, accepts M5 bolts, with a torque range of 30.4±6.1 Kgf∙cm, 26.4±5.3 Lbf∙in, 3.0±0.6 N∙m. The case is made of ABS material and complies with UL 94-HB standard; a flame-retardant 94-V0 version is available upon request. In terms of temperature conditions, the nominal temperature is 25°C; discharge can be performed between -15°C and 50°C, while the charging and storage temperature range is -15°C to 40°C. Regarding design life, it can reach 5 years under float charging at 25°C, and under Eurobat 20°C conditions it meets the 3 to 5 year standard commercial classification. Self-discharge is less than 10% after 90 days, and it can be stored at 25°C for up to 6 months; a full charge is required before use, and if the storage temperature exceeds 25°C, charging should be performed earlier. This product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 recognized, file number MH14533. The official application area is data center UPS, suitable as float standby power.
