Product details

The CSB XHRL12900WFTFR is a 12V front terminal valve-regulated sealed lead-acid battery in the XHRL-FT series, featuring AGM (Absorbent Glass Mat) technology with a gas recombination efficiency of up to 99% and a maintenance-free design. This model is primarily intended for high-rate float standby applications such as data center UPS, and its front terminal configuration makes front-of-cabinet wiring and maintenance more convenient. In terms of power performance, the battery has a nominal capacity of 900W @ 15min-rate, 10.02V per PCS @ 25°C. Individual cell power data is as follows: 2069.83 W/cell at 30 seconds 1.67 VPC @ 25°C, 1403.33 W/cell at 5 minutes 1.67 VPC @ 25°C, and 907.67 W/cell at 15 minutes 1.67 VPC @ 25°C. Maximum charge current is 90.00 A, maximum discharge current is 1900 A (5 seconds), short-circuit current is 5102 A, and internal resistance is 1.86 mΩ. 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, weighing 69.50 kg. The terminal is an I2 thread lead alloy terminal, compatible with M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm, equivalent to 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request. Electrical operating conditions: float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, equalize charge voltage is 14.4 to 15.0 Vdc/battery. Operating temperature: nominal temperature 25°C, discharge range -15°C to 50°C, charge and storage range -15°C to 40°C. Design life is 10 years at 25°C float standby service, and over 12 years Very Long Life under Eurobat (20°C) standard. Self-discharge: less than 10% after 90 days, storage up to 6 months at 25°C, up to 10 months with equalizing charge, fully charge before use, and charge earlier if storage temperature exceeds 25°C. The product features pure lead construction with proprietary elements, is manufactured according to IEC 60896-21/22:2004, and is UL1989 Recognized (MH14533). These characteristics make it suitable for applications such as data center UPS that require high-rate discharge and float standby.
