Product details
In float standby power applications such as data center UPS, the XHRL12475W relies on its high-rate discharge characteristics to meet short-duration high-current demands. The XHRL12475W is a 12V valve-regulated sealed lead-acid battery from CSB, using AGM technology and classified in the XHRL series. As a high-performance variant of HRL, the XHRL series targets UPS and data centers, delivering higher high-rate output. Its nominal voltage is 12 Vdc; under conditions of 25°C and 10.02V per PCS, the 15-minute rate nominal capacity is 475W. The 15-minute rate power is 478.17 W/cell, while the 5-minute rate power reaches 880.17 W/cell, making it suitable for standby power applications requiring short-duration high-power output.
Mechanical specifications: the terminal is an I2 thread lead alloy terminal, can accept M6 bolts, and the terminal torque is 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, and height 216.6±2.5 mm, with a weight of approximately 36.20 kg (79.78 lb). If used in float charge at 25°C, the design life can reach 10 years; under the Eurobat standard (20°C), it reaches the 12+ year Very Long Life rating.
Electrical specifications: internal resistance is 2.30 mΩ, short-circuit current reaches 3449 A; maximum discharge current is 800 A at 5 seconds, and maximum charge current is 47.50 A. At 25°C, the float voltage range is 13.5 - 13.8 Vdc/battery, and the equalization voltage range is 14.4 - 15.0 Vdc/battery. This battery has a valve-regulated sealed construction, gas recombination efficiency up to 99%, and is maintenance-free in use; the case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is also available when required.
Temperature and storage conditions are: nominal temperature 25°C, discharge range -15°C to 50°C, charge and storage range -15°C to 40°C. Self-discharge rate is low: after standing at 25°C for 90 days, remaining capacity is still over 90%; storage time is up to 6 months, and equalization charging can extend it to 10 months. Fully charge before use; when storage temperature is above 25°C, charge in advance. Manufacturing standard is IEC 60896-21/22:2004, and it has obtained UL1989 recognition (MH14533).
Due to its pure lead construction and proprietary elements, the XHRL12475W maintains stable performance in standby service. During installation, pay attention to terminal connection torque and keep the operating temperature within the specified range to preserve battery performance and life.
