Product details
The CSB HRL12280W belongs to the HRL series and is a 12V valve-regulated sealed lead-acid battery using absorbed glass mat (AGM) technology with a gas recombination efficiency of up to 99%, and employs pure lead construction with proprietary elements. The series is officially positioned as a long-life, high-rate UPS pure lead battery series, designed for demanding high-power data center and UPS loads, with the official application area being data center uninterruptible power supplies.
In terms of electrical parameters, the HRL12280W has a voltage of 12 Vdc and a nominal capacity (1.67 VPC @25°C) of 280W @15-minute rate. Its 5-minute rate (1.67 VPC @25°C) power is 506 W/cell, and its 15-minute rate (1.67 VPC @25°C) power is 284 W/cell. The battery's maximum charge current is 28.0 A, maximum discharge current is 800 A, short-circuit current is 2576 A, and internal resistance is 3.50 mΩ. Float charge voltage is 13.5 to 13.8 Vdc/battery (25°C), and equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C).
The battery dimensions are 261.0±2.5 mm length, 168.5±2.0 mm width, and 213.5±2.5 mm height, with a weight of 25.80 lbs (56.86 kg). The terminal type is I2 threaded lead alloy terminal, accepting M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm or 44.9±9.0 Lbf∙in or 5.10±1.0 N∙m. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is available upon request.
In terms of operating environment, 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 less than 10% after 90 days of storage at 25°C, and it can be stored for up to 6 months at 25°C; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged earlier.
