Product details
The CSB XPL8000FT is a member of the XPL-FT series, a 12V front terminal VRLA battery that uses AGM (Absorbent Glass Mat) technology with a gas recombination efficiency of up to 99%, and employs a pure lead construction and dedicated formulation. This series targets high rate UPS and data center backup power, positioned as a front terminal pure lead VRLA battery, with the official designated application being data center uninterruptible power supply.
In terms of power, the nominal capacity of the XPL8000FT at 25°C and 1.67 VPC is as follows: 1831.17 W/cell at 30 seconds, 1287.17 W/cell at 5 minutes, and 821.50 W/cell at 15 minutes; its nominal capacity is expressed as 8000W at the 5-minute rate at 9.60V per PCS and 25°C. The maximum charge current is 66.70 A, the maximum discharge current is 1660 A, the short circuit current is 4570 A, and the internal resistance is 2.17 mΩ.
Dimensions and weight: the battery is 558.0±2.5 mm long, 126.0±1.5 mm wide, and 323.0±2.5 mm high, weighing 65.30 kg. The terminal is an I2 threaded lead alloy type, compatible with M6 bolts, with a torque of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. The case uses PP material (UL 94-HB), and a flame-retardant 94-V0 version is also available on request.
Temperature and charging: at 25°C, the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C; discharge can be performed from -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. At 25°C, self-discharge is less than 10% in 90 days, and the storage period can reach 6 months, extendable to 10 months with equalizing charge; the battery should be fully charged before use, and charged in advance when the storage temperature exceeds 25°C.
Life and compliance: the design life is 10 years under 25°C float standby conditions, and exceeds 12 years under the Eurobat 20°C standard, classified as Very Long Life. The product is manufactured in accordance with IEC 60896-21/22:2004 and has obtained UL1989 Recognized (MH14533). The maintenance-free design plus front terminal construction makes installation and maintenance in cabinets or battery racks more convenient, suitable for float standby power scenarios such as data center UPS.
