Product details
The CSB XHRL12500W belongs to the XHRL series and is a 12V top terminal valve-regulated sealed lead-acid battery using absorbed glass mat (AGM) technology, with gas recombination efficiency of up to 99% and a maintenance-free construction. This series provides higher high-rate output than the HRL series, and its official application area is data center uninterruptible power supplies, making it suitable for float standby power supply situations.
In terms of power performance, the XHRL12500W at 25°C and 10.02V per cell has a nominal capacity of 500W at the 15-minute rate; 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. The battery's maximum charge current is 50.00 A, maximum discharge current is 1200 (5 seconds), short-circuit current is 3685 A, and internal resistance is 2.22 mΩ. These parameters reflect its design orientation toward short-duration high-rate discharge.
The battery 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 36.90 kg. The terminal uses an I2 threaded lead alloy terminal that accepts an M6 bolt, with a terminal torque of 51.7±10.3 Kgf∙cm, i.e. 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case material is PP (UL 94-HB), and a flame-retardant 94-V0 version can also be provided on request.
In terms of charging and temperature, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C, the discharge range is -15°C to 50°C, and the charge and storage range is -15°C to 40°C. For self-discharge, it is less than 10% after 90 days at 25°C, can be stored for up to 6 months, or up to 10 months with equalizing charge; it must be fully charged before use, and should be charged earlier when the storage temperature is above 25°C.
In terms of design life, it can reach 10 years in 25°C float standby service, and more than 12 years under Eurobat 20°C conditions, belonging to Very Long Life. The product is manufactured in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). With its pure lead construction and proprietary formulation, the XHRL12500W is suitable for applications such as data center UPS that require high-rate output and long-term float standby.
