Product details

The HR Series' official application area is data center uninterruptible power supplies. The HR1234W is a 12V valve-regulated sealed lead-acid battery from CSB and is part of the series' high-rate discharge pure lead batteries. The battery uses AGM (absorbent glass mat) technology, and gas recombination efficiency can reach 99%. The series is positioned for UPS with relatively low output power and fast-discharge backup power. Key specifications are as follows: nominal voltage 12 Vdc; nominal capacity 34W @15min-rate (1.67 VPC @25°C). For power output, 5-minute power is 73.0 W/cell, 15-minute power is 34.3 W/cell (1.67 VPC @25°C). Current parameters include maximum charge 3.40 A, maximum discharge 130 A, short-circuit current 349 A; internal resistance 19.0 mΩ. The battery weighs 2.50 kg (5.51 lb), with dimensions length 150.9±2.0 mm, width 64.8±1.0 mm, height 98.6±1.0 mm. Terminal specification F2-Faston Tab250; case material ABS (UL 94-HB); flame-retardant (94-V0) version available if required. Charging and temperature: at 25°C, float charge setting 13.5 - 13.8 Vdc/battery; equalization charge setting 14.4 - 15.0 Vdc/battery. Nominal temperature 25°C; discharge range -15°C to 50°C; charge/storage range -15°C to 40°C. At 25°C float charge, design life can reach 5 years; Eurobat (20°C) standard is 3-5 years. Self-discharge is less than 10% after 90 days at 25°C; can be stored for up to 6 months; fully charge before putting into service; if storage temperature is above 25°C, recharge is required earlier. Standards and certifications: meets IEC 61056-1/2:2012 and is recognized to UL1989 (MH14533). Because it is maintenance-free and uses pure lead construction, this battery can be used in data center UPS and other applications requiring high-rate discharge and float standby.
