Product details
The CSB XHRL12500W is primarily aimed at data center uninterruptible power supplies, i.e. data center UPS, and is especially suitable for float standby power supply. It belongs to the XHRL series and is a 12V top-terminal valve-regulated sealed lead-acid battery enhanced for high-rate output based on HRL; internally it uses an absorbent glass fiber separator, i.e. AGM technology, with gas recombination efficiency up to 99%, and it has a maintenance-free construction.
From the power data, with 1.67 VPC as the end voltage, the 5-minute rate power is 912.17 W/cell, and the 15-minute rate power is 502.83 W/cell; under conditions of 25°C and 10.02V per unit, the 15-minute rate nominal capacity is 500W. The battery has a maximum charge current of 50.00 A, a maximum discharge current of 1200 (5 seconds), a short-circuit current of 3685 A, and internal resistance of 2.22 mΩ. These specifications indicate that its design focus is short-duration high-rate discharge.
In terms of construction dimensions, the battery length is 343.0±2.5 mm, width 170.0±2.0 mm, height 216.6±2.5 mm, and weight approximately 36.90 kg. The case uses PP (UL 94-HB), and a flame-retardant 94-V0 version can also be supplied on request. Terminals are I2 threaded lead alloy terminals and can be fitted with M6 bolts; terminal torque is 51.7±10.3 Kgf∙cm, which converts to 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m.
In terms of temperature and charging, the allowable discharge range is -15°C to 50°C, charging and storage are both -15°C to 40°C, and nominal operating temperature is 25°C. At 25°C, float voltage is 13.5 to 13.8 Vdc/battery, and equalization voltage is 14.4 to 15.0 Vdc/battery. For self-discharge, after 90 days of storage at 25°C it is less than 10%, and it can be stored for up to 6 months; with equalization charging, up to 10 months. It must be fully charged before use; if storage temperature is above 25°C, charge earlier.
In terms of life and certifications, the design life under float standby service at 25°C can reach 10 years; under Eurobat 20°C conditions it exceeds 12 years, falling under Very Long Life. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). With pure lead construction and a proprietary formulation, the XHRL12500W can be used in data center UPS and other scenarios requiring high-rate output and long-term float standby.
