Product details

RUM6290 is a valve-regulated sealed lead-acid battery in the UPS Series from CSB, with terminals located on top; the VRLA-AGM product type covers 6V and 12V. Its official application is data center UPS; this series is positioned as a high-power pure lead UPS battery series for UPS applications. In terms of electrical specifications, this model has a nominal voltage of 6 Vdc; nominal capacity is rated as 290W @5min-rate at 25°C and 9.60V per PCS. At 25°C and 1.67 VPC, the 5-minute power is 94.17 W/cell, and the 15-minute power is 43.50 W/cell. Electrical limits and internal resistance data for this battery are: maximum discharge current 130 A, maximum charge current 4.80 A, short-circuit current 448 A, and internal resistance 6.00 mΩ. At 25°C, each battery requires float charge maintained at 13.5 - 13.8 Vdc and equalize charge at 14.4 - 15.0 Vdc. For self-discharge, loss after 90 days storage at 25°C is less than 10%, maximum storage is 6 months, and it must be fully charged before use; if storage temperature exceeds 25°C, charge it sooner. In terms of construction, the product uses valve-regulated sealed lead-acid design and AGM technology, is maintenance-free, and has a gas recombination efficiency of up to 99%; the pure lead construction with proprietary elements is suitable for high-rate UPS float standby power. The case is ABS (UL 94-HB); a flame-retardant (94-V0) version is available on request. The terminal is F2 terminal - Faston Tab 250. Dimensions are length 150.9±2.0 mm, width 34.0±1.0 mm, height 98.6±1.0 mm, and weight 1.46 kg. For temperature adaptability, nominal temperature is 25°C; discharge temperature range is -15°C to 50°C, and charge and storage temperature range is -15°C to 40°C. Under 25°C float standby conditions, design life is up to 5 years; the Eurobat (20°C) standard corresponds to 3-5 years. Manufacturing is based on IEC 61056-1/2:2012 and it is UL1989 Recognized (MH14533). Therefore, it can be used as a valve-regulated sealed lead-acid battery in float standby applications such as data center UPS.
