Product details
The CSB XHRL12475W belongs to the XHRL series and is a 12V Valve Regulated Sealed Lead Acid battery utilizing AGM technology. The XHRL series is a high-performance derivative of the HRL series, delivering stronger high-rate output for UPS and data center applications. This battery has a nominal voltage of 12 Vdc and, at 25°C and 10.02V per PCS, a 15-minute rate nominal capacity of 475W. Its 5-minute rate power reaches 880.17 W/cell, and its 15-minute rate power is 478.17 W/cell, making it suitable for backup power requirements involving short-duration, high-power output.
Electrically, the XHRL12475W can withstand a maximum charge current of 47.50 A and a discharge current of 800 A (5 seconds), with a short-circuit current of 3449 A and an internal resistance of only 2.30 mΩ. The float charge voltage at 25°C is 13.5 - 13.8 Vdc/battery, and the equalization charge voltage at 25°C is 14.4 - 15.0 Vdc/battery. The battery features a valve regulated sealed design with a gas recombination efficiency of up to 99% and requires no maintenance. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is also available on request.
For terminals, the battery is equipped with an I2 thread lead alloy terminal that accepts an M6 bolt, with 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 343.0±2.5 mm in length, 170.0±2.0 mm in width, and 216.6±2.5 mm in height, with a weight of approximately 36.20 kg (79.78 lb). Under float charge conditions at 25°C, the design life can reach 10 years, and it meets the Eurobat standard (20°C) 12+ year Very Long Life classification.
In terms of 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 battery has a low self-discharge rate, retaining more than 90% capacity after 90 days of storage at 25°C; it can be stored for 6 months, or up to 10 months with equalization charging. It must be fully charged before use, and if the storage temperature exceeds 25°C, it should be charged earlier. The battery is manufactured in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533).
The XHRL12475W is suitable for float backup 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 construction and proprietary elements to ensure stable performance in backup service. During installation, pay attention to the terminal connection torque and ensure the operating temperature remains within the specified range to maintain battery performance and life.
