Product details
The HRL12280W is a 12V Valve Regulated Sealed Lead Acid battery in CSB's HRL series, featuring pure lead grids with proprietary elements and Absorbent Glass Mat (AGM) technology that achieves 99% gas recombination efficiency. This series is officially defined as a high-rate, long-life UPS pure lead battery line, designed for demanding scenarios such as high-power data centers and UPS loads, with the officially designated application being data center uninterruptible power supplies.
In terms of electrical specifications, this battery has a voltage of 12 Vdc and a nominal capacity of 280W at the 15-minute rate under 1.67 VPC @25°C; the 5-minute rate (1.67 VPC @25°C) output power is 506 W/cell, and the 15-minute rate (1.67 VPC @25°C) is 284 W/cell. For charging, the maximum charge current is 28.0 A, the maximum discharge current is 800 A, the short-circuit current is 2576 A, and the measured internal resistance is 3.50 mΩ. The float charge voltage range is 13.5 to 13.8 Vdc/battery (25°C), and the equalize charge voltage range is 14.4 to 15.0 Vdc/battery (25°C).
Physically, the length, width, and height are 261.0±2.5 mm, 168.5±2.0 mm, and 213.5±2.5 mm respectively, with a weight of 25.80 lbs (56.86 kg). The terminal is an I2 threaded lead alloy type, compatible with M6 bolts, with a torque requirement 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); a flame-retardant (94-V0) version is available upon request.
For environmental adaptability, the nominal temperature is 25°C, the allowable discharge temperature is -15°C to 50°C, and charging and storage must be between -15°C and 40°C. In terms of self-discharge, after 90 days at 25°C, the self-discharge rate is less than 10%; it can be stored for up to 6 months at 25°C, and must be fully charged before use; if the storage temperature exceeds 25°C, a supplementary charge should be performed in advance. Regarding design life, it can reach 10 years under float charge at 25°C, meeting the Eurobat standard requirement of greater than 12 years at 20°C, placing it in the ultra-long life category.
This battery features a maintenance-free design, complies with IEC 60896-21/22:2004, and is UL1989 recognized (MH14533). Leveraging its high-rate discharge capability and long life advantages, the HRL12280W can be used in high-power backup power applications such as data center UPS, providing stable power assurance in float standby mode.
