Product details

The CSB RUM6290 is a valve regulated sealed lead acid battery in the UPS series, covering 6V and 12V top terminal VRLA-AGM product types. This model has a nominal voltage of 6 Vdc, and its nominal capacity is expressed as 290W @5min-rate at 9.60V per PCS @ 25°C; at 25°C and 1.67 VPC, the 5-minute power reaches 94.17 W/cell, and the 15-minute power is 43.50 W/cell. This series is positioned as a high-power pure lead UPS battery series, with the official application area being data center uninterruptible power supplies. In terms of electrical parameters, the RUM6290 has a maximum charge current of 4.80 A, a maximum discharge current of 130 A, a short-circuit current of 448 A, and an internal resistance of 6.00 mΩ. At 25°C, the float charge voltage is 13.5 - 13.8 Vdc/battery, and the equalization charge voltage is 14.4 - 15.0 Vdc/battery. Regarding self-discharge characteristics, storage at 25°C for 90 days is less than 10%, and the storage period can reach 6 months, but a full charge is required before use; if the storage temperature exceeds 25°C, charging should be carried out earlier. In terms of construction, this battery uses valve regulated sealed lead acid design and AGM technology, with a gas recombination efficiency of up to 99%, and is maintenance-free; the pure lead construction combined with proprietary elements is designed specifically for high-rate UPS float standby power applications. The case uses ABS (UL 94-HB) material, and a flame-retardant (94-V0) version can be provided on request. The terminal is F2 terminal - Faston Tab 250. Dimensions: length 150.9±2.0 mm, width 34.0±1.0 mm, height 98.6±1.0 mm, weight 1.46 kg. In terms of temperature range, the nominal temperature is 25°C, discharge can be carried out from -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. Under 25°C float standby service, the design life can reach 5 years, and under the Eurobat (20°C) standard it is 3-5 years. The product is manufactured according to IEC 61056-1/2:2012 and has obtained UL1989 Recognized (MH14533). With these characteristics, this battery is suitable for float standby scenarios such as data center uninterruptible power supplies, used as a valve regulated sealed lead acid battery.
