Product details
The HRL12280W, part of the CSB HRL series, is a 12V valve-regulated sealed lead-acid battery. Its core technologies include Absorbent Glass Mat (AGM) separators, gas recombination efficiency of up to 99%, and pure lead construction with proprietary elements. The series is officially positioned as a long-life, high-rate UPS pure lead battery series, primarily designed for demanding high-power data center and UPS loads, with the official application 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 at the 15-minute rate. The 5-minute rate (1.67 VPC @25°C) power is 506 W/cell, and the 15-minute rate (1.67 VPC @25°C) power is 284 W/cell. The maximum charge current is 28.0 A, the maximum discharge current is 800 A, the short-circuit current is 2576 A, and the internal resistance is 3.50 mΩ. Float voltage is 13.5 to 13.8 Vdc/battery (25°C), and equalization voltage is 14.4 to 15.0 Vdc/battery (25°C).
In terms of dimensions and weight, the battery is 261.0±2.5 mm long, 168.5±2.0 mm wide, and 213.5±2.5 mm high, weighing 25.80 lbs (56.86 kg). The terminal is an I2 threaded lead alloy type, accepts M6 bolts, and has a 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.
Operating environment: nominal temperature 25°C, discharge temperature range -15°C to 50°C, charge and storage temperature range -15°C to 40°C. Self-discharge rate is less than 10% after 90 days of storage at 25°C, and the battery can be stored for up to 6 months at 25°C, requiring a full charge before use; if storage temperature exceeds 25°C, recharge earlier. The design life at 25°C float service is up to 10 years, and it meets the Eurobat standard of greater than 12 years at 20°C, placing it in the very long life category.
