Product details

The RUM6290 CSB battery is classified under the UPS series and is a valve-regulated sealed lead-acid battery, covering two product types: 6V and 12V top-terminal VRLA-AGM. Its rated voltage is 6 Vdc; at 25°C and 9.60V per PCS, the nominal capacity is expressed as 290W @5min-rate; at 5 minutes 1.67 VPC @ 25°C, the power reaches 94.17 W/cell; at 15 minutes 1.67 VPC @ 25°C, the power is 43.50 W/cell. The official application scenario for this battery is data center uninterruptible power supplies, and this series is positioned as a high-power pure lead UPS battery series for uninterruptible power supply applications. In terms of electrical parameters, the RUM6290 has a maximum charging 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. The float voltage at 25°C is 13.5 - 13.8 Vdc/battery, and the equalization voltage at the same temperature is 14.4 - 15.0 Vdc/battery. Regarding self-discharge performance, after 90 days of storage at 25°C, self-discharge is less than 10%, and the battery can be stored for up to 6 months, but it must be fully charged before use; once the storage temperature exceeds 25°C, the charging time needs to be advanced accordingly. Structurally, this battery uses a valve-regulated sealed lead-acid design and AGM technology, with a gas recombination efficiency of up to 99%, making it maintenance-free; the pure lead construction combined with proprietary elements is specifically designed for high-rate UPS float standby power applications. The case is made of ABS material (UL 94-HB), and a flame-retardant version (94-V0) is available upon request. The terminal type is F2 terminal - Faston Tab 250. In terms of dimensions, the length is 150.9±2.0 mm, the width is 34.0±1.0 mm, the height is 98.6±1.0 mm, and the weight is 1.46 kg. Regarding temperature conditions, the nominal temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charging and storage temperature range is -15°C to 40°C. The design life is up to 5 years under 25°C float standby service, or 3-5 years according to the Eurobat (20°C) standard. This product is manufactured in accordance with IEC 61056-1/2:2012 and has obtained UL1989 Recognized (MH14533) certification. With these parameters, it is suitable for use as a valve-regulated sealed lead-acid battery in float standby scenarios such as data center uninterruptible power supplies.
