Product details
The CSB XHRL12475W, part of the XHRL series, is a 12V valve-regulated sealed lead-acid battery using AGM technology. As a high-performance upgrade of HRL, this series delivers stronger high-rate power for UPS and data center scenarios. The battery has a nominal voltage of 12 Vdc; at 25°C and 10.02V per PCS, its 15-minute rate nominal capacity is 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 environments requiring short-duration high-power supply.
In terms of electrical parameters, the XHRL12475W has a maximum charge 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 equalization charge voltage is 14.4 - 15.0 Vdc/battery (25°C). Because of its valve-regulated sealed construction, gas recombination efficiency can reach 99%, requiring no maintenance. The case is made of PP material (UL 94-HB), and a flame-retardant (94-V0) version can also be provided upon request.
The battery is equipped with an I2 thread lead alloy terminal, can accept 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: length 343.0±2.5 mm, width 170.0±2.0 mm, height 216.6±2.5 mm, and weight approximately 36.20 kg (79.78 lb). Under 25°C float service, the design life can reach up to 10 years, and it complies with the Eurobat standard (20°C) 12+ year Very Long Life rating.
For 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; after 90 days of storage at 25°C, the remaining capacity is still above 90%, and it can be stored for up to 6 months; if equalization charging is used, this can be extended to 10 months. It must be fully charged before use; if the storage temperature is above 25°C, it should be charged in advance. The battery is manufactured according to the IEC 60896-21/22:2004 standard 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 can meet short-duration high-current needs. The battery uses a pure lead structure and proprietary elements to ensure stable performance in backup service. During installation, attention must be paid to terminal connection torque, and the operating temperature must be kept within the specified range to maintain battery performance and life.
