Product details
The CSB XHRL12900WFTFR belongs to the XHRL-FT series and is a 12V front terminal valve-regulated lead-acid battery using absorbed glass mat (AGM) technology, with gas recombination efficiency up to 99% and a maintenance-free design. This model targets high-rate float standby applications such as data center uninterruptible power supplies, and the front terminal structure facilitates front wiring and maintenance in cabinets.
In terms of power parameters, the battery has a nominal capacity of 900W @ 15min-rate, 10.02V per PCS @ 25°C. Cell power performance is 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. 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.
The battery dimensions are 558.0±2.5 mm length, 126.0±1.5 mm width, and 323.0±2.5 mm height, with a weight of 69.50 kg. The terminal uses an I2 thread lead alloy terminal, accepts an M6 bolt, and the terminal torque is 51.7±10.3 Kgf∙cm, i.e. 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 available upon request.
For electrical operating conditions, the float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. For operating temperature, the nominal temperature is 25°C, the discharge range is -15°C to 50°C, and the charge and storage range is -15°C to 40°C. The design life reaches 10 years in float standby service at 25°C, and over 12 years Very Long Life under the Eurobat (20°C) standard. For self-discharge, it is less than 10% after 90 days, can be stored for up to 6 months at 25°C, and up to 10 months with equalizing charge; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged sooner.
The product uses pure lead construction with proprietary elements, is manufactured according to IEC 60896-21/22:2004, and is UL1989 Recognized (MH14533). These features make it suitable for applications such as data center UPS requiring high-rate discharge and float standby.
