Product details
CSB officially specifies the application area of the HRL12280W as data center uninterruptible power supplies. It belongs to the HRL series and is a 12V valve-regulated sealed lead-acid battery. The series is officially positioned as a long-life, high-rate UPS pure lead battery series, designed to meet demanding high-power data center and UPS loads. The HRL12280W uses AGM (absorbent glass mat) technology and combines pure lead construction with proprietary elements, achieving gas recombination efficiency of up to 99%.
Operating environmental conditions include: nominal temperature 25°C; discharge temperature range -15°C to 50°C; charging and storage temperature range -15°C to 40°C. Stored at 25°C for 90 days, self-discharge rate is less than 10%; it can be stored at 25°C for up to 6 months and should be fully charged before use; if storage temperature exceeds 25°C, charge it in advance. When used in float service at 25°C, design life is up to 10 years; according to Eurobat standard, more than 12 years at 20°C, belonging to the ultra-long-life category.
In terms of electrical parameters, the HRL12280W has a voltage of 12 Vdc; at 1.67 VPC @25°C, nominal capacity reaches 280W at the 15-minute rate. The 5-minute rate (1.67 VPC @25°C) power output is 506 W/cell, and the 15-minute rate (1.67 VPC @25°C) power output is 284 W/cell. 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. At 25°C, the float charge voltage range is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage range is 14.4 to 15.0 Vdc/battery.
Dimensions are as follows: length 261.0±2.5 mm, width 168.5±2.0 mm, height 213.5±2.5 mm; weight is 25.80 lb (56.86 kg). Terminals are I2 threaded lead alloy terminals, compatible with M6 bolts, with torque values 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 on request.
This battery features a maintenance-free design, meets IEC 60896-21/22:2004, and is UL1989 recognized (MH14533). Thanks to its high-rate discharge performance and long-life characteristics, the HRL12280W can be used in high-power backup power applications such as data center UPS, providing reliable power in float standby applications.
