Product details
The CSB XHRL12900WFTFR is a product in the XHRL-FT series, using AGM (Absorbent Glass Mat) technology. It is a 12V front terminal valve regulated sealed lead acid battery type with maintenance-free features and a gas recombination efficiency of 99%. Its target applications include data center uninterruptible power supplies and other occasions requiring high-rate float backup. The front terminal design makes wiring and maintenance from the front of the cabinet more convenient.
In terms of power, the battery has a nominal capacity of 900W @ 15min-rate at 25°C and 10.02V per PCS. The single cell output power is: 2069.83 W/cell at 25°C, 30 seconds, 1.67 VPC; 1403.33 W/cell at 25°C, 5 minutes, 1.67 VPC; 907.67 W/cell at 25°C, 15 minutes, 1.67 VPC. The maximum charge current is 90.00 A, the maximum discharge current is 1900 A (5 seconds), the short circuit current is 5102 A, and the internal resistance is 1.86 mΩ.
In terms of dimensions and weight, length 558.0±2.5 mm, width 126.0±1.5 mm, height 323.0±2.5 mm, weight 69.50 kg. The terminal uses an I2 thread lead alloy terminal, supports M6 bolts, and the torque specification is 51.7±10.3 Kgf∙cm, which is 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m after conversion. The case is made of PP (UL 94-HB) material, and a flame retardant (94-V0) version can also be supplied on request.
In terms of electrical conditions, the float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage is 14.4 to 15.0 Vdc/battery. Temperature suitability: nominal temperature 25°C, discharge allowed from -15°C to 50°C, charge and storage allowed from -15°C to 40°C. The design life in 25°C float backup mode can reach 10 years, and exceeds 12 years under the Eurobat (20°C) standard, which is the Very Long Life level. Self-discharge characteristics: less than 10% after 90 days, can be stored for 6 months at 25°C, and can be extended to 10 months if equalization charging is used; it must be fully charged before use, and when the storage temperature exceeds 25°C, it needs to be charged in advance.
In terms of manufacturing, this product uses a pure lead construction and proprietary elements, complies with the IEC 60896-21/22:2004 standard, and has obtained UL1989 Recognized (MH14533). Therefore, it is suitable for scenarios such as data center UPS that require both high-rate discharge and float backup.
