Product details
CSB XHRL12900WFTFR is based on the XHRL-FT series platform, rated 12V, and is a front-terminal valve-regulated sealed lead-acid battery; its AGM approach uses absorbent glass mat separators, with gas recombination efficiency up to 99%, and requires no water replenishment during use. The front terminal layout makes front wiring and routine maintenance in cabinets more convenient, and it is intended for high-rate float standby applications such as data center UPS.
In terms of dimensions, the battery is 558.0±2.5 mm long, 126.0±1.5 mm wide, and 323.0±2.5 mm high, with a weight of 69.50 kg; the terminal is I2 thread lead alloy terminal, compatible with M6 bolts, torque 51.7±10.3 Kgf∙cm, equivalent to 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case uses PP (UL 94-HB); a flame-retardant (94-V0) version can also be provided if required.
Nominal capacity is 900W @ 15min-rate, 10.02V per PCS @ 25°C. For per-cell output, at 1.67 VPC @ 25°C: 2069.83 W/cell at 30 seconds, 1403.33 W/cell at 5 minutes, and 907.67 W/cell at 15 minutes. Current parameters include maximum charge current 90.00 A, 5-second maximum discharge current 1900 A, short-circuit current 5102 A, and internal resistance 1.86 mΩ.
Charging and temperature conditions: float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, equalization voltage 14.4 to 15.0 Vdc/battery; nominal temperature is 25°C, discharge range is -15°C to 50°C, and charging and storage range is -15°C to 40°C. Under float standby service at 25°C, design life can reach 10 years; the Eurobat (20°C) standard is over 12 years, Very Long Life. Regarding self-discharge, it is less than 10% after 90 days on shelf; it can be stored for 6 months at 25°C, extended to 10 months with equalizing charge. It should be fully charged before being put into service; if storage temperature is above 25°C, charge earlier.
The product uses pure lead construction and proprietary elements, is manufactured to IEC 60896-21/22:2004, and is UL1989 Recognized (MH14533). These features make it suitable for high-rate discharge and float standby applications such as data center UPS.
