Product details
The CSB XHRL12475W is a 12V valve-regulated lead-acid battery using AGM technology, belonging to the XHRL series. This series is a high-performance variant of HRL, providing higher high-rate output for UPS and data center requirements. The battery has a nominal voltage of 12 Vdc and a 15-minute rate nominal capacity of 475W at 25°C and 10.02V per PCS. Its 5-minute rate power is 880.17 W/cell and 15-minute rate power is 478.17 W/cell, making it suitable for standby power applications requiring short-duration high-power output.
In terms of electrical performance, the XHRL12475W has a maximum charging current of 47.50 A, a maximum discharge current of 800 A (5 seconds), a short-circuit current of 3449 A, and an internal resistance of 2.30 mΩ. The float charge voltage is 13.5 - 13.8 Vdc/battery (25°C), and the equalizing charge voltage is 14.4 - 15.0 Vdc/battery (25°C). The battery features a valve-regulated sealed design with a gas recombination efficiency of up to 99%, and is maintenance-free. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request.
The battery terminal is an I2 thread lead alloy terminal, accepts M6 bolts, and has a terminal torque of 51.7±10.3 Kgf∙cm or 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. Dimensions are length 343.0±2.5 mm, width 170.0±2.0 mm, height 216.6±2.5 mm, and weight is approximately 36.20 kg (79.78 lb). The design life can reach 10 years under 25°C float charge service, and it meets the Eurobat standard (20°C) 12+ year Very Long Life rating.
Regarding operating temperature, the nominal temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. The self-discharge rate is low, with remaining capacity over 90% after 90 days at 25°C; it can be stored for up to 6 months, extendable to 10 months with equalizing charge. It must be fully charged before use, and if storage temperature exceeds 25°C, it should be charged earlier. The battery is manufactured according to IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533).
The XHRL12475W is suitable for float standby power applications such as data center UPS, and its high-rate discharge characteristics meet short-duration high-current requirements. The battery uses a pure lead structure and proprietary elements to ensure stable performance in standby service. During installation, attention must be paid to terminal connection torque and ensuring the operating temperature is within the specified range to maintain battery performance and life.
